Product details
Overview
P6SMB200AH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 190–210 V, clamping voltage of 274 V at 2.2 A peak pulse current, and stand-off voltage of 171 V. It features glass-passivated junction, AEC-Q101 qualification, and DO-214AA (SMB) package for automotive-grade ESD and surge protection in power supply rails.
For engineers reviewing the P6SMB200AH datasheet, P6SMB200AH pinout, P6SMB200AH application, or P6SMB200AH equivalent, key selection criteria include its 274 V clamping performance at 2.2 A, 171 V working voltage, AEC-Q101 qualification, moisture sensitivity level 1 rating, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive transients.
Technical Context
The P6SMB200AH operates as a unidirectional avalanche diode optimized for fast clamping of high-energy transients. Its 10/1000 μs waveform rating supports 600 W non-repetitive peak pulse power, with thermal resistance RθJA = 55 °C/W enabling reliable operation up to 150 °C junction temperature.
Designed for automotive and industrial DC power line protection, it delivers sub-1 ps response time from 0 V to VBR(min), <1 μA reverse leakage above 10 V, and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements in its SMB package.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same 200 V nominal VBR, but 600 W rating with VC = 324 V at 1.9 A; higher clamping voltage than P6SMB200AH's 274 V at 2.2 A | Less effective clamping headroom for 24 V systems near upper rail limits | Select P6SMB200AH where tighter clamping (274 V) is critical for protecting 28 V-rated components |
| 1.5SMC200A | Higher 1500 W rating, DO-214AB (SMC) package; VC = 324 V at 4.6 A; larger footprint and 2× thermal mass | Over-specified for PCB space-constrained 24 V automotive modules | Choose P6SMB200AH for SMB footprint compatibility, AEC-Q101 qualification, and optimal 274 V clamping in compact layouts |
Compared with SMBJ200A and 1.5SMC200A, the P6SMB200AH offers superior clamping voltage (274 V), AEC-Q101 validation, and SMB footprint-making it the preferred choice for space-limited, automotive-qualified 24 V rail protection where low VC and reliability are prioritized over raw power rating.

FAQ
What is the clamping voltage of the P6SMB200AH and how is it measured?
The P6SMB200AH has a maximum clamping voltage (VC) of 274 V, measured at a peak pulse current (IPPM) of 2.2 A using the standardized 10/1000 μs double-exponential waveform. This value represents the highest voltage the device allows across its terminals during a transient event, ensuring downstream components remain below their absolute maximum ratings. The P6SMB200AH achieves this clamping performance while maintaining a 171 V stand-off voltage, providing a 103 V design margin.
Is the P6SMB200AH suitable for automotive applications?
Yes, the P6SMB200AH is AEC-Q101 qualified and explicitly designed for automotive environments. It meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements, supports junction temperatures up to +150 °C, and carries moisture sensitivity level 1 (MSL 1) for zero-bake reflow processing. These attributes make the P6SMB200AH appropriate for engine control units, body control modules, and ADAS power supplies where reliability under thermal and electrical stress is mandatory.
What is the difference between P6SMB200AH and P6SMB200H?
The P6SMB200AH features a tighter breakdown voltage tolerance (190–210 V) compared to the P6SMB200H (180–220 V), resulting in more consistent clamping behavior and improved design margin control. Both share identical package (DO-214AA), power rating (600 W), and thermal specifications, but the 'A' suffix denotes enhanced VBR uniformity-critical for applications requiring precise overvoltage thresholding, such as regulated 24 V power distribution networks where the P6SMB200AH reduces worst-case clamping variance.
Does the P6SMB200AH have polarity markings and what is its orientation in circuit?
Yes, the P6SMB200AH uses a DO-214AA (SMB) package with a visible cathode band marking one end. In unidirectional operation, the banded end connects to the protected line (e.g., 24 V rail), and the opposite (anode) end connects to ground or the return path. This orientation ensures forward conduction only during reverse-biased transients, allowing normal DC operation with leakage under 1 μA at 171 V. The P6SMB200AH's polarity marking is laser-etched per JEDEC standards for automated optical inspection.
What packaging and reel options are available for the P6SMB200AH?
The P6SMB200AH is supplied in tape-and-reel format with 3,000 units per reel, compatible with standard SMT pick-and-place equipment. The reel complies with EIA-481-D standards, and the carrier tape features embossed pockets with cover tape sealing. Each reel includes traceable lot coding per J-STD-033, and the P6SMB200AH's MSL 1 rating eliminates bake requirements-enabling direct placement after dry pack opening. Aetrix Electronics supports custom reel splits and kitting for prototype and NPI builds.
