Product details

Overview

P6SMB200 from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 180–220 V, clamping voltage of 287 V at 2.1 A peak pulse current, and DO-214AA (SMB) package. It protects power supplies and adapters against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.

For engineers reviewing the P6SMB200 datasheet, P6SMB200 pinout, P6SMB200 application, or P6SMB200 equivalent, key selection criteria include standoff voltage (162 V), clamping performance under 10/1000 µs surge, junction temperature rating (−55 to +150 °C), and compliance with RoHS and halogen-free standards.

Technical Context

The P6SMB200 operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its minimum breakdown voltage (180 V). It exhibits fast response (<1.0 ps rise time) and low leakage (<1 µA at 162 V), enabling reliable overvoltage clamping in DC power rails.

Its thermal design supports 10 °C/W junction-to-case resistance and 55 °C/W junction-to-ambient resistance, with steady-state power dissipation rated at 3 W. The device uses glass-passivated chip junction construction and matte tin-plated leads compliant with J-STD-002 solderability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR (min/max)	180 V / 220 V - defines minimum and maximum voltage at which avalanche conduction begins under 1 mA test current
V_WM	162 V - maximum continuous reverse operating voltage before significant leakage occurs
V_C @ I_PPM	287 V at 2.1 A - clamped voltage during 10/1000 µs surge, limiting downstream circuit stress
P_PPSM	600 W - non-repetitive peak pulse power handling capability per standard waveform
I_R @ V_WM	<1 µA - ensures minimal standby power loss and signal integrity in high-impedance circuits
T_J Range	−55 °C to +150 °C - supports operation in automotive under-hood and industrial power-conversion environments

Pinout & Package

Package: DO-214AA (SMB), surface-mount, single-diode configuration with cathode band marking. Weight: ~0.090 g. Meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry / Reverse voltage reference	Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration
Cathode	Reverse voltage input / Clamping node	Connected to protected line (e.g., DC input rail); conducts when V_REV > V_BR, shunting surge to ground

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ200A	Breakdown range 185–215 V; clamping voltage 274 V at 2.2 A; same DO-214AA package	Lower V_C improves margin for 200 V-rated systems but requires verification of V_BR min (185 V) vs. system turn-on threshold	Select SMBJ200A if tighter V_BR tolerance and lower clamping are prioritized over legacy footprint compatibility
1.5SMC200A	Higher power rating (1500 W); larger DO-214AB (SMC) package; V_C = 287 V at 5.2 A	Requires PCB layout change; suited for higher-energy surge environments (e.g., outdoor PoE injectors)	Choose 1.5SMC200A only when 600 W is insufficient and mechanical redesign is acceptable

Compared with SMBJ200A and 1.5SMC200A, the P6SMB200 offers optimal balance of 600 W surge capacity, SMB footprint compatibility, and 162 V standoff in cost-sensitive consumer power designs-without requiring layout revision or over-spec'ing power rating.

FAQ

What is the maximum clamping voltage of the P6SMB200 under standard 10/1000 µs surge conditions?

The P6SMB200 has a maximum clamping voltage (V_C) of 287 V when subjected to its rated peak pulse current of 2.1 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream components such as MOSFETs and electrolytic capacitors in the protected circuit.

Is the P6SMB200 suitable for bidirectional transient suppression?

No, the P6SMB200 is a unidirectional TVS diode intended for DC line protection where polarity is fixed. For bidirectional applications (e.g., AC lines or data lines), the P6SMB200A variant or devices with "C" or "CA" suffixes must be used, as they feature symmetrical breakdown characteristics in both directions.

What is the standoff voltage (V_WM) rating for the P6SMB200, and why does it matter?

The P6SMB200 has a standoff voltage (V_WM) of 162 V, meaning it remains non-conductive up to this reverse voltage under normal operation. This rating ensures no significant leakage current flows during nominal DC operation-critical for maintaining efficiency and preventing false triggering in 150–200 V power rails.

Does the P6SMB200 meet automotive transient immunity standards?

Yes, the P6SMB200 meets ISO 7637-2 requirements for Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling), making it suitable for front-end protection in automotive infotainment power modules and body control unit auxiliary supplies.

What packaging and reel quantity is offered for the P6SMB200?

The P6SMB200 is supplied in DO-214AA (SMB) package format on tape-and-reel, with 3,000 units per reel. This configuration supports high-speed automated pick-and-place assembly and complies with moisture sensitivity level 1 (MSL-1), eliminating pre-bake requirements before reflow soldering.
