TOSHIBA Schottky Barrier Rectifier Schottky Barrier Type CMS10 CMS10 Switching Mode Power Supply Applications Portable Equipment Battery Applications Unit: mm • Forward voltage: VFM = 0.55 V (max) • Average forward current: IF (AV) = 1.0 A • Repetitive peak reverse voltage: VRRM = 40 V • Suitable for compact assembly due to small surface-mount package “M−FLATTM” (Toshiba package name) Absolute Maximum Ratings (Ta = 25°C) Characteristics Symbol Rating Unit Repetitive peak reverse voltage Average forward current (Note 1) VRRM IF (AV) 40 1.0 (Ta = 21°C) V A Peak one cycle surge forward current (non-repetitive) IFSM 25 (50 Hz) A Junction temperature Storage temperature Tj −40~150 °C Tstg −40~150 °C JEDEC JEITA ― ― Note 1: Device mounted on a glass-epoxy board (board size: 50 mm × 50 mm, soldering land: 6 mm × 6 mm) Note 2: Using continuously under heavy loads (e.g. the application of TOSHIBA 3-4E1A Weight: 0.023 g (typ.) high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

There is a possibility SBD may cause thermal runaway when it is used under high temperature or high voltage. Please take forward and reverse loss into consideration during design. The absolute maximum ratings denote the absolute maximum ratings, which are rated values and must not be exceeded during operation, even for an instant. The following are the general derating methods that we recommend when you design a circuit with a device. VRRM: Use this rating with reference to the above. VRRM has a temperature coefficient of 0.1%/°C. Take this temperature coefficient into account designing a device at low temperature. IF(AV): We recommend that the worst case current be no greater than 80% of the absolute maximum rating of IF(AV) and Tj be below 120°C. When using this device, take the margin into consideration by using an allowable Tamax-IF(AV) curve. IFSM: This rating specifies the non-repetitive peak current. This is only applied for an abnormal operation, which seldom occurs during the lifespan of the device. Tj: Derate this rating when using a device in order to ensure high reliability. We recommend that the device be used at a Tj of below 120°C. Thermal resistance between junction and ambient fluctuates depending on the device’s mounting condition. When using a device, design a circuit board and a soldering land size to match the appropriate thermal resistance value. Please refer to the Rectifiers databook for further information. 2 2013-11-01 Instantaneous forward current iF (A) iF – vF 10 Tj = 150°C 125°C 75°C 1 25°C 0.1 0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 Instantaneous forward voltage vF (V) Ta max – IF (AV) Device mounted on a glass-epoxy board (board size: 50 mm × 50 mm, land size 6 mm × 6 mm) 160 Rectangular waveform 140 120 DC 0° α 360° 100 IF (AV) α = 180° Conduction angle: α 80 α = 120° VR = 20 V 60 40 α = 60° 20 0 0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 Average forward current IF (AV) (A) Maximum allowable lead temperature Ta max (°C) Average forward power dissipation PF (AV) (W) CMS10 PF (AV) – IF (AV) 0.8 Rectangular waveform 0.7 DC 0.6 0° α 360° 0.5 Conduction angle: α α = 180° α = 120° 0.4 α = 60° 0.3 0.2 0.1 0 0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 Average forward current IF (AV) (A) Ta max – IF (AV) Device mounted on a ceramic board (board size: 50 mm × 50 mm) 160 140 120 100 α = 60° 80 Rectangular waveform 60 DC α = 180° α = 120° 40 0° α 360° 20 IF (AV) Conduction angle: α 0 VR = 20 V 0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 Average forward current IF (AV) (A) 1.6 Maximum allowable ambient temperature Ta max (°C) Transient thermal impedance rth (j-a) (°C/W) 500 100 1.
