Taiwan Semiconductor Corporation BZW06-213BH

Overview

BZW06-213BH from Taiwan Semiconductor is a unidirectional 600W Transient Voltage Suppressor (TVS) diode with a 213V working stand-off voltage, 250V nominal breakdown voltage (V_BR), and 344V clamping voltage at 2.0A (10/1000μs). It features AEC-Q101 qualification, low dynamic impedance, and sub-1ps response time for automotive-grade ESD and surge protection in power supply rails and signal lines.

For engineers reviewing the BZW06-213BH datasheet, BZW06-213BH pinout, BZW06-213BH application, or BZW06-213BH equivalent, key selection criteria include its DO-204AC (DO-15) package, 175°C maximum junction temperature, 2.0A peak pulse current rating, and AEC-Q101 qualification for under-hood automotive systems requiring robust transient immunity.

Technical Context

The BZW06-213BH operates as a unidirectional avalanche diode, conducting only during reverse overvoltage events above its 250V V_BR threshold while maintaining <1μA leakage at 213V. Its clamping action limits transients to ≤344V at 2.0A (10/1000μs), enabling protection of downstream 24V–48V DC systems against ISO 7637-2 pulses and IEC 61000-4-5 surges.

Thermally, it delivers 600W non-repetitive peak power dissipation with R_θJL = 60°C/W and R_θJA = 100°C/W (L = 10mm), supporting operation from –55°C to +175°C. The device uses pure tin-plated leads compliant with J-STD-002 and meets JESD 201 Class 2 whisker resistance.

FAQ

What is the polarity configuration of the BZW06-213BH?

The BZW06-213BH is a unidirectional TVS diode, with cathode marked by a band on the DO-204AC (DO-15) package. It conducts only during reverse overvoltage events-i.e., when the cathode is at higher potential than the anode-and blocks forward current like a standard rectifier diode. This configuration ensures precise clamping on positive-going transients on grounded-return systems, as confirmed in the device's marking diagram and electrical characteristics table.

Does the BZW06-213BH meet AEC-Q101 requirements?

Yes, the "H" suffix in BZW06-213BH explicitly denotes AEC-Q101 qualification per the ordering information section of the datasheet. This includes stress testing for temperature cycling, high-temperature operating life, unbiased highly accelerated stress test (uHAST), and mechanical shock-all validated for automotive under-hood applications. The qualification applies specifically to the BZW06-213BH variant, not the entire BZW06 series.

What is the maximum clamping voltage of the BZW06-213BH under standard test conditions?

The BZW06-213BH has a maximum clamping voltage (V_C) of 344 V at a peak pulse current (I_PPM) of 2.0 A using the 10/1000μs waveform, as specified in the "Maximum Ratings and Electrical Characteristics" table. This value is measured at T_A = 25°C and defines the upper voltage limit imposed on protected circuitry during standardized surge events.

Can the BZW06-213BH be used in bidirectional configurations?

No-the BZW06-213BH is strictly unidirectional. Bidirectional variants in the same series carry the "B" suffix (e.g., BZW06-213B). Using the BZW06-213BH in bidirectional signal paths would result in unintended forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always match the suffix to the required polarity configuration.

What is the thermal resistance from junction to lead (R_θJL) for the BZW06-213BH?

The junction-to-lead thermal resistance (R_θJL) for the BZW06-213BH is 60°C/W, as published in the Thermal Performance table. This parameter enables accurate calculation of junction temperature rise under steady-state power dissipation (e.g., 1.7W at T_L = 75°C) and supports thermal design validation for mounting on PCBs with copper pour or heatsinking leads.
