Product details
Overview
BZW06-40H from Taiwan Semiconductor is a unidirectional 600W Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, with 44.7V minimum breakdown voltage (VBR), 40.2V working stand-off voltage (VWM), and 64.8V clamping voltage (VC) at 9.3A peak pulse current under 10/1000μs waveform - designed for automotive-grade ESD and inductive load transient protection in lighting and power control systems.
For engineers reviewing the BZW06-40H datasheet, BZW06-40H pinout, BZW06-40H application, or BZW06-40H equivalent, key selection criteria include AEC-Q101 qualification, low dynamic impedance, sub-1ps response time, <1μA reverse leakage above 10V, and thermal robustness up to 175°C junction temperature.
Technical Context
The BZW06-40H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 44.7–49.4V breakdown range (tested at 1mA). It clamps transients to ≤64.8V at 9.3A (10/1000μs), delivering 600W peak pulse power with <1.0ps response from 0V to VBR.
Its DO-204AC package provides 60°C/W junction-to-lead thermal resistance and supports 100A non-repetitive forward surge current. The device maintains stable performance across –55°C to +175°C operating junction temperature, with ±0.101%/°C VBR temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 40.2 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min) | 44.7 V @ 1 mA - Minimum voltage at which avalanche breakdown reliably initiates |
| VC @ IPPM | 64.8 V @ 9.3 A (10/1000μs) - Clamped voltage during worst-case surge, limiting downstream stress |
| PPK | 600 W - Peak transient power handling capability per single 1ms pulse |
| IR @ VWM | <1 μA - Low leakage ensures minimal standby power loss and signal integrity |
| TJ max | +175 °C - Enables use in under-hood automotive environments without derating |
| RθJL | 60 °C/W - Efficient heat transfer to PCB leads supports sustained surge duty cycles |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, cathode-banded end marking. Lead finish: pure tin, solderable per J-STD-002. Weight: 0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance return in unidirectional clamp configuration |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., 12V rail); conducts when Vin > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, lighting, and body electronics |
| 600W surge rating (10/1000μs) | Withstands high-energy transients from load dump or inductive switching without failure |

| Response time <1.0 ps | Activates faster than most semiconductor switching events, preventing voltage overshoot damage |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and global environmental directives for industrial and automotive use |
Applications
| Automotive Lighting Systems | Industrial Motor Drive Protection |
|---|---|
Use Scenario: Protecting LED driver ICs and MOSFET gate drivers from load-dump spikes and relay coil flyback in headlamp modules. IC Role / Device Role: Unidirectional TVS placed between supply rail and ground to clamp positive transients. Use Value: Limits voltage to ≤64.8V during 600W surges, preserving 40V-rated driver ICs and enabling AEC-Q101-compliant system certification. | Use Scenario: Safeguarding PLC I/O circuitry and H-bridge controllers against inductive kickback from solenoids and DC motors. IC Role / Device Role: Primary transient suppressor on 24V DC input rails upstream of regulators and interface ICs. Use Value: Sub-1ps response and low dynamic impedance prevent latch-up or gate oxide rupture in sensitive logic and power stages. |
| Automotive Body Control Modules | ESD-Prone Sensor Interfaces |
Use Scenario: Shielding LIN bus transceivers and window lift motor drivers from battery reversal and jump-start transients. IC Role / Device Role: Standoff-rated TVS on 12V supply inputs with VWM = 40.2V ensuring no conduction during normal operation. Use Value: Maintains <1μA leakage at rated voltage, avoiding false triggers and minimizing quiescent current in always-on modules. | Use Scenario: Protecting automotive ambient light sensors and Hall-effect position sensors from ESD events per ISO 10605. IC Role / Device Role: Low-capacitance unidirectional clamp on analog signal lines referenced to chassis ground. Use Value: Fast clamping action limits ESD-induced voltage excursion to safe levels before sensor front-end amplifiers saturate or fail. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ40A | Same DO-214AA package; 40V VWM, 64.5V VC @ 9.3A, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial designs only | Select SMBJ40A only if AEC-Q101 compliance is not required and DO-214AA footprint is preferred |
| P6SMB40A | Same 600W rating, 40V VWM, 64.5V VC; RoHS-compliant but AEC-Q101 status unspecified | Uncertified for automotive use; may require additional qualification testing for vehicle programs | Prefer BZW06-40H where automotive qualification, traceability, and guaranteed thermal performance are mandatory |
Compared with SMBJ40A and P6SMB40A, the BZW06-40H delivers verified AEC-Q101 qualification, tighter VBR tolerance (44.7–49.4V vs. typical 42.2–47.8V), and documented 60°C/W RθJL - critical for thermal reliability in high-ambient automotive environments.

FAQ
What is the AEC-Q101 qualification status of the BZW06-40H?
The BZW06-40H is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H" and datasheet revision K2105. This certification covers stress tests including high-temperature operating life, temperature cycling, and ESD, confirming suitability for automotive powertrain and body electronics applications. BZW06-40H meets all requirements without derating.
How does the BZW06-40H differ from the non-H version BZW06-40?
The BZW06-40H includes full AEC-Q101 qualification, extended temperature screening, and enhanced process controls versus the standard BZW06-40. Both share identical electrical parameters (VWM = 40.2V, VC = 64.8V), but only BZW06-40H carries automotive-grade traceability, lot-level test reports, and guaranteed thermal performance per JESD22-A108.
What is the maximum peak pulse current the BZW06-40H can handle?
The BZW06-40H handles 9.3A peak pulse current (IPPM) under the standard 10/1000μs waveform while clamping to 64.8V. At the 8/20μs waveform, it sustains 48.0A with a clamping voltage of 84.0V. These values are measured per JEDEC standards and confirmed in the BZW06-40H datasheet Table on page 2.
Is the BZW06-40H unidirectional or bidirectional?
The BZW06-40H is a unidirectional TVS diode, indicated by its single cathode band marking and specification of VBR and VC only for reverse polarity. It conducts only when the cathode is positive relative to the anode - ideal for protecting positive-rail circuits. Bidirectional variants (e.g., BZW06-40BH) are separate orderable parts.
What is the thermal resistance and maximum junction temperature of the BZW06-40H?
The BZW06-40H has a junction-to-lead thermal resistance (RθJL) of 60°C/W and a maximum junction temperature (TJ) of +175°C. These values are specified under steady-state conditions with 9.5mm lead length and enable reliable operation in under-hood automotive locations where ambient temperatures exceed 125°C.
