Product details
Overview
BZW06-70BH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode with a 70.1V working stand-off voltage, 77.9–86.1V breakdown voltage range, and 113V clamping voltage at 5.3A (10/1000μs). It features AEC-Q101 qualification, low dynamic impedance, and sub-1ps response time for automotive-grade ESD and load-dump protection in power supply rails.
For engineers reviewing the BZW06-70BH datasheet, BZW06-70BH pinout, BZW06-70BH application, or BZW06-70BH equivalent, key selection criteria include its DO-204AC (DO-15) package, unidirectional polarity, 175°C max junction temperature, and compliance with IEC 61249-2-21 halogen-free and RoHS standards.
Technical Context
The BZW06-70BH operates as a unidirectional avalanche diode, clamping transients above its VWM (70.1V) by entering breakdown at VBR (min 77.9V, typ 82V, max 86.1V) and limiting peak voltage to 113V under 5.3A 10/1000μs surge. Its thermal design supports 175°C operation with RθJL = 60°C/W and RθJA = 100°C/W.
It delivers 600W non-repetitive peak pulse power per JEDEC standard waveform, with <1μA reverse leakage at rated VWM and a temperature coefficient of 0.105%/°C for VBR stability across -55°C to +175°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 70.1 V - Maximum continuous DC or RMS voltage the device blocks without clamping |
| VBR @ IT=1mA | 77.9–86.1 V - Breakdown voltage range defining reliable avalanche onset under standardized test current |
| VC @ IPPM=5.3A (10/1000μs) | 113 V - Clamped voltage during worst-case automotive load dump, determining protected circuit stress level |

| TJ max | +175 °C - Maximum junction temperature enabling under-hood deployment without derating in high-ambient environments |
| IR @ VWM | <1 μA - Ultra-low leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ70A | Same DO-214AA package; 70V VWM, 113V VC @ 5.3A, but only 600W PPK and no AEC-Q101 qualification | Not approved for automotive under-hood use; suitable for industrial/commercial power supplies | Select SMBJ70A if AEC-Q101 is not required and board space permits SMC/SMB footprint |
| 1.5KE70A | DO-201AD package; identical 70V VWM and 113V VC, but lower 1.5kW PPK rating and higher 1.5μA IR | Higher surge capacity suits heavy-duty industrial motor drives, but larger size limits high-density layouts | Choose 1.5KE70A when >600W surge margin is needed and DO-201AD mechanical fit is acceptable |
Compared with SMBJ70A and 1.5KE70A, the BZW06-70BH uniquely combines AEC-Q101 qualification, DO-204AC form factor, and precise 113V clamping in a 0.4g axial package-making it optimal for space-constrained automotive modules requiring certified reliability.

FAQ
What is the polarity configuration of the BZW06-70BH?
The BZW06-70BH is a unidirectional TVS diode with cathode-band marking indicating the high-side terminal. When reverse-biased above its 70.1V working stand-off voltage, it avalanches to clamp transients from cathode to anode. This configuration is optimized for DC power rail protection where polarity is fixed, unlike bidirectional variants such as BZW06-70B.
Does the BZW06-70BH meet AEC-Q101 requirements for automotive use?
Yes, the BZW06-70BH is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirming full stress testing across temperature cycling, humidity, mechanical shock, and ESD per automotive reliability standards. This certification validates its suitability for engine control, body electronics, and ADAS power domains where failure modes must be rigorously controlled.
What is the clamping voltage of the BZW06-70BH under standard test conditions?
The BZW06-70BH has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current using the 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during worst-case transients, ensuring compatibility with 100V-rated downstream components.
How does the thermal performance of the BZW06-70BH support high-temperature operation?
The BZW06-70BH supports operation up to +175°C junction temperature with a junction-to-lead thermal resistance (RθJL) of 60°C/W. When mounted with 9.5mm lead lengths per JEDEC, its thermal path efficiently transfers surge energy to the PCB copper, enabling sustained reliability in under-hood automotive environments without forced cooling or derating.
Is the BZW06-70BH halogen-free and RoHS compliant?
Yes, the BZW06-70BH uses halogen-free molding compound compliant with IEC 61249-2-21 and meets EU RoHS Directive 2011/65/EU requirements. Its pure tin-plated leads are solderable per J-STD-002, and the entire construction avoids restricted substances including brominated flame retardants and lead, supporting environmentally regulated supply chains.
