Taiwan Semiconductor Corporation BZW06-13H

Overview

BZW06-13H from Taiwan Semiconductor is an AEC-Q101 qualified unidirectional transient voltage suppressor diode (TVS) in DO-204AC (DO-15) package, rated for 600W peak pulse power at 10/1000μs, with 12.8V working stand-off voltage, 14.3–15.8V breakdown voltage at 1mA, and clamping voltage of 21.2V at 28.0A. It protects automotive and industrial power rails against ESD, EFT, and inductive switching transients.

For engineers reviewing the BZW06-13H datasheet, BZW06-13H pinout, BZW06-13H application, or BZW06-13H equivalent, key selection criteria include its AEC-Q101 qualification, low dynamic impedance, sub-1ps response time from 0V to V_BR, <1μA reverse leakage above 10V, and DO-15 mechanical compatibility with high-reliability board-level surge protection layouts.

Technical Context

The BZW06-13H operates as a unidirectional silicon avalanche diode, leveraging controlled PN-junction avalanche breakdown to clamp transient overvoltages before they reach downstream ICs. Its thermal design supports junction temperatures from –55°C to +175°C, with R_θJL = 60°C/W enabling effective lead-based heat dissipation under repetitive surge conditions.

It delivers stable clamping performance across ambient temperatures due to a temperature coefficient of 0.084%/°C on V_BR, and maintains low capacitance (<100pF at 1MHz) suitable for DC power line and low-speed signal line protection without signal integrity degradation.

FAQ

What does the "H" suffix signify in BZW06-13H?

The "H" suffix in BZW06-13H indicates full AEC-Q101 qualification per Rev-D, including stress testing for temperature cycling, high-temperature reverse bias, and ESD robustness. This distinguishes it from standard BZW06-13 variants and confirms suitability for automotive powertrain and chassis applications where reliability certification is mandatory. The BZW06-13H meets all test conditions defined in the AEC-Q101 standard without derating.

Is BZW06-13H unidirectional or bidirectional?

BZW06-13H is a unidirectional TVS diode, designed to protect against positive-going transients on DC power lines. Its cathode-marked terminal connects to the protected line, and anode to ground. Unlike bidirectional variants (e.g., BZW06-13B), it does not conduct on negative excursions - making it ideal for 12V battery rail protection where reverse polarity is handled separately. This configuration ensures minimal leakage and optimal clamping precision.

What is the maximum clamping voltage of BZW06-13H at rated surge current?

The BZW06-13H has a maximum clamping voltage (V_C) of 21.2 V at a peak pulse current (I_PPM) of 28.0 A under the 10/1000μs waveform. This value is measured per JEDEC Std. 28 and guarantees that protected downstream components - such as 3.3V or 5V LDOs and microcontrollers - experience no more than 21.2V stress during worst-case surge events, well within their absolute maximum voltage ratings.

Can BZW06-13H be used in place of BZW06-13 without design changes?

No - BZW06-13H and BZW06-13 are not interchangeable without verification. While both share identical electrical parameters and DO-15 packaging, only BZW06-13H carries AEC-Q101 qualification. Using BZW06-13 in automotive applications may violate functional safety requirements (e.g., ISO 26262 ASIL-B), and its reliability data under thermal cycling or HTOL stress is not validated. Always specify BZW06-13H where automotive qualification is required.

What is the thermal resistance from junction to lead for BZW06-13H?

The junction-to-lead thermal resistance (R_θJL) of BZW06-13H is 60°C/W, measured under standard test conditions with 9.5mm lead length. This parameter enables accurate thermal modeling when estimating junction temperature rise during repetitive surge events - for example, at 28.0A peak current and 600W pulse, a 1.7W steady-state dissipation yields ~102°C rise above ambient, staying within the +175°C T_JMAX limit when ambient remains ≤73°C.
