Product details
Overview
P6SMB200H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 180–220 V, stand-off voltage of 162.0 V, and clamping voltage of 287 V at 2.1 A peak pulse current. 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 P6SMB200H datasheet, P6SMB200H pinout, P6SMB200H application, or P6SMB200H equivalent, key selection criteria include its 287 V clamping performance under 10/1000 µs surge, <1 µA reverse leakage at 162 V, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive transients.
Technical Context
The P6SMB200H operates as a unidirectional avalanche diode, activated when reverse voltage exceeds its 180–220 V breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1 µA @ VWM), while thermal resistance values (RθJC = 10 °C/W, RθJA = 55 °C/W) support reliable operation up to 150 °C junction temperature.
Designed for single-die, single-direction surge suppression, it delivers 600 W non-repetitive peak pulse power per 10/1000 µs waveform and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements - critical for automated SMT assembly in harsh-environment automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 180 V / 220 V - defines minimum and maximum voltage at which avalanche conduction begins under 1 mA test current |
| VWM | 162.0 V - maximum continuous reverse operating voltage before significant leakage occurs |
| VC @ IPPM | 287 V @ 2.1 A - clamped voltage during 10/1000 µs surge, limiting downstream circuit stress |
| PPPSM | 600 W - peak pulse power handling capability under standardized surge waveform |
| IR @ VWM | <1 µA - ultra-low reverse leakage ensures minimal standby power loss and signal integrity |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| Package | DO-214AA (SMB) - industry-standard surface-mount outline with 0.090 g mass and matte tin-plated leads |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with cathode band marking; terminals are matte tin-plated for J-STD-002 solderability; polarity is unidirectional with cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse surge return path | Connected to system ground or low-side reference; completes clamping loop during transient events |
| Cathode | Reverse voltage sensing / Clamping output node | Connected to protected line (e.g., 24 V rail); conducts avalanche current when VREV > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress-test requirements including temperature cycling, HTRB, and ESD |
| Glass passivated junction | Enhances long-term VBR stability and reduces parameter drift over lifetime and thermal cycling |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance coupled noise) |
| Low-profile SMB package | Enables high-density PCB layout and compatibility with standard pick-and-place equipment for automotive module manufacturing |
| J-STD-020 Level 1 moisture rating | Eliminates need for pre-bake prior to reflow, reducing production cost and process complexity |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs against load dump and alternator-induced surges in passenger vehicles. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between power rail and chassis ground to clamp transients above 162 V. Use Value: Limits peak voltage to 287 V during 600 W surges, preventing damage to downstream regulators and microcontrollers. | Use Scenario: Safeguarding programmable logic controllers (PLCs) powered from 24 V industrial supplies exposed to relay switching noise. IC Role / Device Role / Timing Role: Standoff protector on main DC input, absorbing repetitive 10/1000 µs pulses without degradation. Use Value: Maintains <1 µA leakage at 162 V, ensuring no measurable impact on system quiescent current or sensor reference accuracy. |
| LED Driver Overvoltage Clamp | Telecom Line Interface Protection |
Use Scenario: Shielding constant-current LED drivers in commercial lighting systems from mains-coupled surges. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output to shunt overvoltage before reaching LEDs or MOSFETs. Use Value: Fast response (<1 ps rise time) ensures clamping initiates before LED forward voltage exceeds safe limits. | Use Scenario: Front-end protection for PoE-powered network switches handling 48 V DC input with lightning-induced transients. IC Role / Device Role / Timing Role: Primary surge limiter on DC input side, coordinated with secondary TVS and filtering stages. Use Value: 287 V clamping level aligns with 48 V system derating margins, preserving upstream DC-DC converter reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same DO-214AA package; bidirectional variant with symmetric VBR (180–220 V) and higher VC (324 V @ 1.85 A) | Required where AC-coupled or reversible polarity lines need protection (e.g., RS-485 bus) | Select SMBJ200A only if bidirectional clamping is required; P6SMB200H offers lower clamping (287 V) for unidirectional rails. |
| 1.5SMC200A | Larger DO-214AB (SMC) package; identical electrical specs but higher thermal mass (RθJA = 40 °C/W vs. 55 °C/W) | Better suited for high-ambient-temperature environments (>105 °C) due to improved heat dissipation | Choose 1.5SMC200A when board space allows and thermal margin is constrained; P6SMB200H prioritizes compactness and SMT automation. |
Compared with SMBJ200A and 1.5SMC200A, P6SMB200H provides optimal balance of low-profile packaging, automotive qualification, and tight 287 V clamping - making it preferred for space-constrained, unidirectional 24 V/48 V automotive and industrial power rails.

FAQ
What is the clamping voltage of P6SMB200H and how is it measured?
The P6SMB200H has a maximum clamping voltage (VC) of 287 V, measured at a peak pulse current (IPPM) of 2.1 A using the standardized 10/1000 µs double-exponential surge waveform. This value reflects the actual voltage seen by protected circuitry during worst-case transient events and is guaranteed per the device's electrical specifications table in the official Taiwan Semiconductor datasheet revision A2102.
Is P6SMB200H unidirectional or bidirectional, and how can I identify its polarity?
P6SMB200H is a unidirectional TVS diode. Polarity is marked by a cathode band on the DO-214AA (SMB) package body - the banded end connects to the protected line (cathode), while the unbanded end connects to ground (anode). Bidirectional variants in this family use "CH" or "CAH" suffixes (e.g., P6SMB200AH), which are electrically distinct and not interchangeable with P6SMB200H.
Does P6SMB200H meet automotive qualification standards?
Yes, P6SMB200H is AEC-Q101 qualified and tested per the full stress-test suite including HTGB, H3TRB, TC, and mechanical shock. It also complies with ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b for automotive transient immunity - confirming its suitability for engine control units, body electronics, and ADAS power domains where reliability under harsh conditions is mandatory.
What is the maximum steady-state power dissipation of P6SMB200H at room temperature?
The P6SMB200H has a steady-state power dissipation (Ptot) rating of 3 W at ambient temperature (TA) = 25 °C. This value applies only to continuous DC or low-frequency reverse bias conditions - not surge events. For transient suppression, the device relies on its 600 W non-repetitive peak pulse power rating (PPPSM), which dominates design considerations for surge protection applications.
Can P6SMB200H be used in place of P6SMB200AH?
No, P6SMB200H and P6SMB200AH are not interchangeable. P6SMB200H is unidirectional with VBR = 180–220 V and VC = 287 V, while P6SMB200AH is bidirectional with symmetric breakdown and higher clamping (328 V). Their marking codes (NSJ vs. NTJ), polarity configuration, and electrical behavior differ fundamentally - substituting one for the other risks failure to suppress AC transients or unintended conduction in DC systems.
