Product details
Overview
BZW06-171H from Taiwan Semiconductor is a unidirectional 600W Transient Voltage Suppressor (TVS) diode with a 171V working stand-off voltage (VWM), 190–210V breakdown voltage (VBR), and 274V clamping voltage (VC) at 2.2A peak pulse current under 10/1000μs waveform. 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 BZW06-171H datasheet, BZW06-171H pinout, BZW06-171H application, or BZW06-171H equivalent, key selection criteria include its DO-204AC (DO-15) package, unidirectional polarity, 175°C maximum junction temperature, and compliance with automotive reliability standards for in-vehicle electronics protection.
Technical Context
The BZW06-171H operates as a unidirectional avalanche diode, designed to clamp transient overvoltages above its VBR threshold while maintaining low leakage (<1μA at 171V). Its thermal design supports 60°C/W junction-to-lead resistance and 100°C/W junction-to-ambient resistance with 10mm lead length.
It delivers 600W non-repetitive peak pulse power per 10/1000μs waveform, with clamping performance validated across ambient temperatures from –55°C to +175°C. The device exhibits a temperature coefficient of 0.108%/°C for VBR, enabling predictable voltage drift in high-temperature environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VWM | 171 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/typ/max) | 190 / 200 / 210 V - Breakdown voltage range at 1 mA test current; defines turn-on threshold consistency |
| VC @ IPPM | 274 V at 2.2 A (10/1000μs) - Clamped voltage during surge; determines protected circuit's max stress level |
| PPK | 600 W - Peak pulse power handling capacity; enables robust protection against ISO 7637-2 Pulse 1/2a/5a transients |
| TJ MAX | +175 °C - Maximum junction temperature; supports under-hood automotive deployment without derating |
| IR @ VWM | <1 μA - Reverse leakage at rated stand-off voltage; ensures minimal standby power loss in always-on systems |
| RθJL | 60 °C/W - Junction-to-lead thermal resistance; informs heatsinking requirements for sustained surge duty cycles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170A | Same DO-214AA package; 170V VWM, 189–209V VBR, 274V VC @ 2.2A; 600W rating; no AEC-Q101 qualification | Designed for industrial/commercial use only; not validated for automotive temperature cycling or vibration | Select SMBJ170A where AEC-Q101 is not required and board space allows DO-214AA footprint |
| P6SMB170A | DO-214AA package; identical electrical specs (170V VWM, 274V VC); RoHS-compliant but AEC-Q101 not stated in datasheet | Limited qualification documentation for automotive use; typically used in consumer and computing power supplies | Prefer P6SMB170A for cost-sensitive commercial designs where full AEC-Q101 traceability is unnecessary |
Compared with SMBJ170A and P6SMB170A, the BZW06-171H provides verified AEC-Q101 qualification, DO-204AC (DO-15) axial form factor for through-hole mounting, and tighter VBR tolerance (190–210V vs. 189–209V), making it preferred for automotive under-hood applications requiring mechanical robustness and long-term reliability validation.

FAQ
What is the polarity configuration of the BZW06-171H?
The BZW06-171H is a unidirectional TVS diode, marked with a cathode band on the DO-204AC (DO-15) package. It conducts in reverse bias above its breakdown voltage and blocks forward current like a standard diode. This polarity ensures proper clamping on positive-going transients in 12V/24V automotive rails, and the BZW06-171H must be oriented with cathode toward the protected line and anode to ground.
Does the BZW06-171H meet AEC-Q101 requirements for automotive use?
Yes, the BZW06-171H is explicitly AEC-Q101 qualified, as confirmed by Taiwan Semiconductor's ordering code suffix "H" and documented in the BZW06 series datasheet revision K2105. This qualification covers temperature cycling, mechanical shock, humidity testing, and high-temperature operating life - validating the BZW06-171H for under-hood and chassis-mounted automotive applications.
What is the maximum clamping voltage of the BZW06-171H under standard test conditions?
The BZW06-171H has a maximum clamping voltage (VC) of 274 V at 2.2 A peak pulse current using the 10/1000μs waveform, per the manufacturer's electrical characteristics table. This value defines the upper voltage limit imposed on protected circuitry during surge events and is measured with specified test conditions - the BZW06-171H maintains this clamping performance across its full operating temperature range.
Can the BZW06-171H be used in bidirectional configurations?
No, the BZW06-171H is strictly unidirectional. Bidirectional variants in the same series carry the "B" suffix (e.g., BZW06-171B). Using the BZW06-171H for bidirectional protection would leave negative-going transients unclamped. For symmetrical surge suppression, select BZW06-171B or pair two BZW06-171H devices in series opposition - but the BZW06-171H itself does not support bidirectional operation.
What is the thermal resistance profile of the BZW06-171H in typical PCB mounting?
The BZW06-171H has a junction-to-lead thermal resistance (RθJL) of 60°C/W and a junction-to-ambient resistance (RθJA) of 100°C/W with 10mm lead length. In standard through-hole PCB mounting with 25mm² copper pour per lead, actual RθJA may improve to ~75°C/W. These values directly impact safe surge repetition rate - the BZW06-171H requires adequate copper area and airflow to avoid thermal accumulation during repeated transients.
