Product details
Overview
P6SMB200CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It provides clamping protection for automotive-grade signal lines, sensor interfaces, and power rails in industrial and telecom systems.
For engineers reviewing the P6SMB200CAHM3/H datasheet, P6SMB200CAHM3/H pinout, P6SMB200CAHM3/H application, or P6SMB200CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, low thermal resistance (RθJL = 20 °C/W), and MSL Level 1 moisture sensitivity.
Technical Context
This TVS diode operates symmetrically in both directions, with identical electrical characteristics for forward and reverse transients. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the SMB package supports automated SMT placement and meets UL 94 V-0 flammability rating.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2. With 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), it delivers predictable overvoltage suppression without latch-up or degradation under repetitive surge conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200CA | Same VWM/VBR/VC ratings but lower PPPM (400 W); SMA package (DO-214AC), higher RθJA (150 °C/W) | Limited to lower-energy transients; unsuitable for automotive AEC-Q101 environments | Select only for cost-sensitive commercial designs with verified <400 W surge exposure |
| SMCJ200CA | Higher PPPM (1500 W); larger SMC (DO-214AB) package; same VWM/VBR; not AEC-Q101 qualified in standard grade | Requires PCB area increase (~2.5× SMB footprint); lacks automotive qualification unless specified HE3/HM3 variant | Choose when system-level surge testing exceeds 600 W, and layout allows larger footprint |
Compared with SMAJ200CA and SMCJ200CA, P6SMB200CAHM3/H uniquely balances 600 W surge capability, AEC-Q101 qualification, SMB footprint, and halogen-free compliance-making it optimal for space-constrained automotive and industrial modules requiring certified reliability.

FAQ
What is the clamping voltage of P6SMB200CAHM3/H at its rated peak pulse current?
The P6SMB200CAHM3/H has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current (IPPM) of 2.2 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during surge events.
Is P6SMB200CAHM3/H suitable for automotive applications?
Yes, P6SMB200CAHM3/H is AEC-Q101 qualified (denoted by the HM3 suffix) and explicitly validated for automotive use cases including sensor protection, body electronics, and infotainment interfaces. Its qualification covers high-temperature operating life, humidity bias, and mechanical shock testing per the AEC standard.
Does P6SMB200CAHM3/H have polarity markings on the package?
No, P6SMB200CAHM3/H is a bidirectional TVS diode and carries no polarity marking on the SMB (DO-214AA) package. Both terminals are functionally identical, allowing unrestricted orientation during PCB placement-unlike unidirectional variants that feature a cathode band.
What is the thermal resistance from junction to lead (RθJL) for P6SMB200CAHM3/H?
The P6SMB200CAHM3/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in the Thermal Characteristics table of Vishay document 88370. This low value enables effective heat transfer to PCB copper pads, supporting reliable operation under repetitive surge conditions without external heatsinking.
How does the HM3 suffix affect the compliance status of P6SMB200CAHM3/H?
The HM3 suffix in P6SMB200CAHM3/H indicates halogen-free, RoHS-compliant construction and AEC-Q101 qualification. It distinguishes this variant from commercial-grade E3/M3 versions and confirms compliance with automotive environmental and reliability standards, including JESD201 Class 2 whisker resistance.
