Taiwan Semiconductor Corporation BZW06-213

Overview

BZW06-213 from Taiwan Semiconductor is a unidirectional 600W Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It features a 213V working stand-off voltage (VWM), 237–263V breakdown voltage (VBR) at 1mA, 344V clamping voltage (VC) at 2.0A (10/1000μs), and operates across –55°C to +175°C junction temperature range.

For engineers reviewing the BZW06-213 datasheet, BZW06-213 pinout, BZW06-213 application, or BZW06-213 equivalent, key selection criteria include clamping performance under 10/1000μs surges, AEC-Q101 qualification status, DO-204AC package thermal resistance (R_θJL = 60°C/W), and low leakage (<1μA @ 213V).

Technical Context

The BZW06-213 functions as a unidirectional avalanche diode that enters conduction when reverse voltage exceeds its VBR (min 237V), limiting transient overvoltage to ≤344V at 2.0A peak pulse current. Its fast response time (<1.0ps from 0V to VBR) ensures protection against ESD and electrical fast transients before sensitive downstream circuitry is damaged.

Thermally, it sustains 600W non-repetitive peak power (10/1000μs) with junction-to-lead thermal resistance of 60°C/W and maximum junction temperature of 175°C. The device uses pure tin-plated leads compliant with J-STD-002 and meets JESD201 Class 2 whisker resistance.

FAQ

What is the maximum clamping voltage of the BZW06-213 under standard 10/1000μs surge conditions?

The BZW06-213 has a maximum clamping voltage (VC) of 344 V when subjected to a 2.0 A peak pulse current with a 10/1000μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events. The BZW06-213 maintains this clamping performance across its full operating temperature range, making it suitable for under-hood automotive deployments where thermal stability is critical.

Is the BZW06-213 AEC-Q101 qualified, and how is qualification indicated in the part number?

The base BZW06-213 is not automatically AEC-Q101 qualified; qualification is indicated by the "H" suffix-i.e., BZW06-213H. This variant undergoes full stress testing per AEC-Q101 Rev D, including HTOL, temperature cycling, and unbiased HAST. The BZW06-213H is intended for automotive powertrain and body electronics applications where component-level reliability validation is contractually required. Standard BZW06-213 remains suitable for industrial use.

What is the thermal resistance from junction to ambient (R_θJA) for the BZW06-213 in standard PCB mounting?

The BZW06-213 has a typical junction-to-ambient thermal resistance (R_θJA) of 100°C/W when mounted on a standard FR-4 PCB with 10 mm lead length, per JEDEC JESD51-2. This value assumes no additional copper pour or heatsinking. For higher-power or elevated-temperature applications, designers should verify actual board layout thermal performance using the specified R_θJL = 60°C/W and apply appropriate derating curves from the BZW06-213 datasheet.

Can the BZW06-213 be used in bidirectional configurations, and what is the correct variant?

The BZW06-213 is unidirectional; for bidirectional transient suppression, the correct variant is BZW06-213B. Both share identical VWM (213 V), VBR (237–263 V), and VC (344 V @ 2.0 A) specifications, but the BZW06-213B has symmetrical breakdown behavior and no cathode marking. It is used in AC-coupled or differential-line protection where polarity reversal must be tolerated-such as telecom DC feeds or RS-485 bus lines-without requiring external polarity management.

What is the reverse leakage current specification for the BZW06-213 at its rated working voltage?

The BZW06-213 exhibits a maximum reverse leakage current (IR) of 1 μA when biased at its full working stand-off voltage of 213 V, measured at 25°C. This ultra-low leakage preserves system standby power budgets and avoids false triggering in high-impedance sensing circuits. Leakage remains below 5 μA up to 175°C junction temperature, ensuring stable performance in thermally demanding environments such as engine control units or industrial motor drives.
