Product details
Overview
P6SMB100CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 100 V standoff voltage (VWM), 137 V maximum clamping voltage (VC) at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects sensitive ICs and MOSFETs against inductive switching transients and lightning surges in automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the P6SMB100CAHE3/5B datasheet, P6SMB100CAHE3/5B pinout, P6SMB100CAHE3/5B application, or P6SMB100CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 137 V VC at 4.4 A, 100 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical breakdown behavior in both directions due to its bidirectional construction. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 0.01% duty cycle pulses.
Designed for surface-mount use on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, it delivers 600 W peak pulse power while maintaining TJ ≤ 150 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.

IC Role / Device Role / Timing Role: Across-motor terminals or between motor driver H-bridge outputs and ground to limit inductive kickback voltage. Use Value: Prevents false triggering and overvoltage failure in motor driver ICs by clamping spikes to 137 V, enabling compact PCB layout without external snubbers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same SMB package, 100 V VWM, but 139 V VC at 4.3 A; not AEC-Q101 qualified | Limited to commercial/industrial use; lacks automotive reliability validation | Select when AEC-Q101 is not required and cost optimization is prioritized |
| 1.5SMC100CA | Higher 1500 W PPPM rating, DO-214AB package (larger footprint), 139 V VC at 10.9 A | Requires larger PCB area; suited for higher-energy surge environments (e.g., outdoor telecom) | Choose for enhanced surge margin where board space permits and 1500 W rating is mandated |
Compared with SMBJ100CA and 1.5SMC100CA, P6SMB100CAHE3/5B uniquely combines AEC-Q101 qualification, SMB footprint efficiency, and verified 600 W surge capability-making it optimal for space-constrained automotive and industrial designs requiring production-grade reliability.

FAQ
What is the clamping voltage of P6SMB100CAHE3/5B at its rated peak pulse current?
The P6SMB100CAHE3/5B has a maximum clamping voltage (VC) of 137 V at its specified peak pulse current (IPPM) of 4.4 A with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and defines the upper voltage limit imposed on protected circuits during surge events. The 137 V VC ensures downstream components like microcontrollers and transceivers remain within safe operating limits.
Is P6SMB100CAHE3/5B suitable for automotive applications?
Yes, P6SMB100CAHE3/5B is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. The HE3 suffix denotes RoHS-compliant and AEC-Q101 qualified construction, and its MSL Level 1 rating supports lead-free reflow processes used in automotive manufacturing. Its bidirectional clamping and 100 V standoff make it ideal for protecting CAN, LIN, and analog sensor lines.
How does the SMB (DO-214AA) package of P6SMB100CAHE3/5B compare to larger TVS packages like DO-214AB?
The SMB (DO-214AA) package of P6SMB100CAHE3/5B measures 4.57 mm × 3.94 mm × 2.20 mm, offering 30% smaller footprint than DO-214AB (used in 1.5SMC series). While DO-214AB supports higher power ratings (e.g., 1500 W), the SMB enables denser layouts in space-constrained applications such as automotive ECUs and portable industrial sensors-without sacrificing 600 W surge capability or AEC-Q101 compliance.
What is the maximum operating junction temperature for P6SMB100CAHE3/5B?
The maximum operating junction temperature (TJ max) for P6SMB100CAHE3/5B is +150 °C, as specified in the Vishay datasheet. This rating allows reliable operation in under-hood automotive environments and industrial enclosures with elevated ambient temperatures. Derating curves in Figure 2 confirm usable power dissipation down to 50% at 125 °C ambient, supporting thermal design margins in sealed or convection-limited assemblies.
Does P6SMB100CAHE3/5B require polarity-aware PCB layout?
No, P6SMB100CAHE3/5B is a bidirectional TVS diode and carries no polarity marking on the SMB package. Its symmetrical construction means either terminal can serve as anode or cathode depending on transient polarity-eliminating orientation constraints during automated placement. This simplifies layout for differential or floating signal lines, unlike unidirectional variants (e.g., P6SMB100A) which require strict cathode-band alignment.
