Product details
Overview
P6SMB200CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used in automotive sensor protection, industrial I/O interfaces, and telecom line surge suppression.
For engineers reviewing the P6SMB200CAHM3_A/I datasheet, P6SMB200CAHM3_A/I pinout, P6SMB200CAHM3_A/I application, or P6SMB200CAHM3_A/I equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification status, SMB (DO-214AA) package thermal resistance (RθJA = 100 °C/W), and compliance with halogen-free, RoHS-compliant manufacturing standards.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the 10/1000 μs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5.
Thermally, it supports operation from −65 °C to +150 °C junction temperature, with derating above 25 °C ambient per Fig. 2. The SMB (DO-214AA) package enables automated placement and meets UL 94 V-0 flammability rating, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same VWM (200 V), VC = 324 V at 1.8 A; lower PPPM (600 W same), but higher clamping voltage and non-AEC-Q101 rated. | Not qualified for automotive use; suitable for commercial/industrial equipment where AEC-Q101 is not mandated. | Select SMBJ200CA only if AEC-Q101 compliance is unnecessary and board space allows for higher clamping margin. |
| 1.5SMC200CA | Same VWM (200 V), VC = 324 V at 1.8 A; larger SMC (DO-214AB) package (7.11 mm × 6.22 mm), RθJA ≈ 50 °C/W, higher IPPM (2.0 A). | Higher thermal mass supports higher average surge repetition rates; requires larger PCB footprint than SMB. | Choose 1.5SMC200CA when thermal performance under repetitive surges outweighs size constraints, and AEC-Q101 is not required. |
Compared with SMBJ200CA and 1.5SMC200CA, P6SMB200CAHM3_A/I delivers tighter clamping (274 V vs. 324 V), AEC-Q101 qualification, and SMB footprint efficiency - making it optimal for space-constrained automotive and industrial designs demanding certified reliability and low clamping overshoot.

FAQ
What is the clamping voltage of P6SMB200CAHM3_A/I at its rated peak pulse current?
The P6SMB200CAHM3_A/I has a maximum clamping voltage (VC) of 274 V at a peak pulse current (IPPM) of 2.2 A, measured under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring compatibility with downstream ICs rated for ≤300 V absolute maximum voltage. The P6SMB200CAHM3_A/I achieves this clamping performance while maintaining low incremental surge resistance and fast response time.
Is P6SMB200CAHM3_A/I suitable for automotive applications?
Yes, P6SMB200CAHM3_A/I is AEC-Q101 qualified, as indicated by the "HM3" suffix denoting halogen-free, RoHS-compliant, and automotive-grade construction. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification per AEC-Q101 Rev D. The P6SMB200CAHM3_A/I is deployed in engine control units, ADAS camera modules, and body electronics where reliability under thermal and electrical stress is mandatory.
What does the "CA" suffix mean in P6SMB200CAHM3_A/I?
The "CA" suffix in P6SMB200CAHM3_A/I designates a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression for both positive and negative polarity surges without requiring polarity orientation during PCB placement. Unlike unidirectional variants (e.g., P6SMB200A), the P6SMB200CAHM3_A/I has no cathode band marking and functions identically across both terminals, simplifying layout for AC-coupled or floating interfaces like RS-485, CAN, or sensor bridges.
What is the thermal resistance of P6SMB200CAHM3_A/I, and how does it affect PCB layout?
The P6SMB200CAHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal copper area; increasing pad size or adding thermal vias reduces RθJA and improves surge repetition capability. For reliable operation under repeated transients, PCB layout must allocate adequate copper area per terminal and avoid narrow traces that increase thermal impedance - directly impacting the P6SMB200CAHM3_A/I's ability to dissipate 600 W peak pulses.
How does P6SMB200CAHM3_A/I compare to unidirectional P6SMB200AHM3_A/I in circuit implementation?
The P6SMB200CAHM3_A/I differs from the unidirectional P6SMB200AHM3_A/I in polarity behavior: the "CA" version clamps surges in both directions and requires no orientation during placement, whereas the "A" version has a marked cathode and only protects against reverse-polarity transients. In practice, the P6SMB200CAHM3_A/I replaces two unidirectional devices in differential-line protection or eliminates polarity-check steps in automated assembly - reducing BOM count and improving yield. Its VWM (200 V) and VC (274 V) are identical to the unidirectional variant at equivalent current levels.
