Product details
Overview
P6SMB200A from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a standoff voltage of 171 V, breakdown voltage range of 190–210 V, and clamping voltage of 274 V at 2.2 A peak pulse current. It protects power rails in switching mode power supplies and industrial adapters against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB200A datasheet, P6SMB200A pinout, P6SMB200A application, or P6SMB200A equivalent, key selection criteria include its 600 W peak pulse power rating, DO-214AA (SMB) package compatibility with automated placement, <1 µA reverse leakage at 171 V, and 1.0 ps response time - critical for high-speed surge immunity in 200 V-class DC systems.
Technical Context
The P6SMB200A operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve stable breakdown behavior and low thermal resistance (RθJC = 10 °C/W). Its clamping action begins at VBR ≥ 190 V under 1 mA test current and limits transient energy within a 10/1000 µs waveform envelope.
Designed for automotive-grade transient suppression, it meets ISO 7637-2 Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling noise), with junction temperature rated from –55 °C to +150 °C and moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VBR (min/max) | 190 / 210 V - breakdown occurs within this range at 1 mA, defining reliable turn-on threshold |
| VC @ IPPM | 274 V at 2.2 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPSM | 600 W - non-repetitive peak pulse power handling capability per standard waveform |
| IR @ VWM | <1 µA - ultra-low leakage ensures minimal standby power loss in high-impedance circuits |
| TJ max | +150 °C - enables operation in under-hood or enclosed power supply environments |
| Response time | <1.0 ps - sub-picosecond junction response ensures protection before system-level damage |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, single-diode configuration with cathode band marking. Matte tin-plated leads meet J-STD-002 solderability; weight ≈ 0.090 g.

Applications
| Switching Mode Power Supply (SMPS) | Industrial Adapter |
|---|---|
Use Scenario: Protection of primary-side DC bus against inductive kickback and line surges in offline SMPS designs. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed across bulk capacitor or rectifier output to clamp transients before they reach controller ICs. Use Value: Limits voltage excursion to ≤274 V during 600 W surges, preserving MOSFET gate oxide integrity and PWM controller operation. | Use Scenario: Surge suppression on 170–200 V DC output rails of universal-input industrial AC/DC adapters. IC Role / Device Role / Timing Role: Standoff-rated transient protector that remains inert below 171 V but clamps within nanoseconds when line spikes exceed VBR. Use Value: Enables compliance with IEC/EN 61000-4-5 Level 3 (2 kV line-earth) without adding bulkier MOVs or RC snubbers. |
| Televisions (TV) | Monitors |
Use Scenario: Input-stage protection for main power board in large-screen TVs with wide-range AC inputs (90–264 VAC). IC Role / Device Role / Timing Role: Primary transient shunt on PFC output or main DC rail, coordinated with upstream fuse and NTC thermistor. Use Value: Withstands repetitive 10/1000 µs pulses up to 600 W, preventing latch-up or burnout in high-density PCB layouts. | Use Scenario: DC input rail protection in commercial-grade monitors exposed to shared building power disturbances. IC Role / Device Role / Timing Role: Fast-acting unidirectional clamp on 19 V–24 V auxiliary or 170 V main rail, sized to handle localized ESD and lightning-induced surges. Use Value: Delivers <1 µA leakage at 171 V, eliminating standby current penalty while maintaining robust 274 V clamping performance. |
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 DO-214AA package, identical VWM/VBR/VC specs, but from STMicroelectronics; RθJA = 50 °C/W vs. 55 °C/W | Identical use cases; slightly better thermal dissipation in still-air conditions | Select SMBJ200A if prioritizing marginally improved ambient thermal performance in convection-cooled designs |
| 1.5SMC200A | DO-214AB (SMC) package - larger footprint and higher PPPSM (1500 W), but same electrical ratings | Requires PCB layout change; suited for higher-energy surge environments where 600 W is marginal | Choose 1.5SMC200A only when system-level testing shows P6SMB200A approaches thermal limit under repeated surges |
Compared with SMBJ200A and 1.5SMC200A, the P6SMB200A offers optimal balance of compact DO-214AA footprint, certified ISO 7637-2 immunity, and production-ready moisture sensitivity level 1 - making it preferred for space-constrained, high-volume automotive and industrial adapter designs.

FAQ
What is the polarity configuration of the P6SMB200A?
The P6SMB200A is a unidirectional TVS diode, configured with an anode and cathode terminal. The cathode is marked by a band on the DO-214AA package body. It conducts only during reverse overvoltage events on the cathode side - meaning it must be installed with cathode toward the protected line and anode toward ground or lower potential. This polarity is confirmed in the device's marking diagram and absolute maximum ratings table.
Does the P6SMB200A meet automotive transient standards?
Yes, the P6SMB200A meets ISO 7637-2 Pulse 1 (load dump), Pulse 2a/2b (supply disconnection and inductive switching), and Pulse 3a/3b (capacitive coupling) requirements. This compliance is explicitly stated in the FEATURES section of the official datasheet and validated via standardized 10/1000 µs waveform testing. The P6SMB200A is routinely deployed in automotive power modules and infotainment power supplies.
What is the maximum clamping voltage of the P6SMB200A and at what current is it specified?
The maximum clamping voltage (VC) of the P6SMB200A is 274 V, measured at a peak pulse current (IPPM) of 2.2 A under the standard 10/1000 µs waveform. This value appears in the ELECTRICAL SPECIFICATIONS table for P6SMB200A and defines the upper voltage limit imposed on the protected circuit during worst-case transient events.
Can the P6SMB200A be used in bidirectional configurations?
No - the P6SMB200A is strictly unidirectional. For bidirectional operation, Taiwan Semiconductor specifies the P6SMB200CA variant (with 'C' or 'CA' suffix). The P6SMB200A lacks symmetrical breakdown characteristics and will not suppress positive-going transients on the anode side. Using it in bidirectional roles risks failure or incomplete protection.
What is the junction-to-ambient thermal resistance (RθJA) of the P6SMB200A?
The junction-to-ambient thermal resistance (RθJA) of the P6SMB200A is 55 °C/W, as published in the THERMAL PERFORMANCE section of the datasheet. This value assumes standard JEDEC high-K test board conditions (2s2p copper) and determines steady-state temperature rise under continuous power dissipation - critical for derating calculations in enclosed or high-ambient-temperature applications.
