Product details
Overview
BZW06-33H from Taiwan Semiconductor is a unidirectional 600W Transient Voltage Suppressor (TVS) diode with a working stand-off voltage of 33.3 V, breakdown voltage range of 37.1–47.0 V, and clamping voltage of 53.9 V at 11.1 A (10/1000 µs). It features low dynamic impedance, <1 µA reverse leakage above 10 V, and AEC-Q101 qualification for automotive-grade reliability. It protects power rails and I/O lines in lighting control and industrial sensor interfaces.
For engineers reviewing the BZW06-33H datasheet, BZW06-33H pinout, BZW06-33H application, or BZW06-33H equivalent, key selection criteria include its DO-204AC (DO-15) package, unidirectional polarity, 175 °C max junction temperature, and compliance with electrical fast transient (EFT) immunity standards per IEC 61000-4-4.
Technical Context
The BZW06-33H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified VBR (min 37.1 V), rapidly clamping transients to ≤53.9 V at 11.1 A. Its junction-to-lead thermal resistance is 60 °C/W, enabling effective heat dissipation during surge events.
Designed for single-pulse 10/1000 µs waveform protection, it delivers 600 W peak pulse power with sub-nanosecond response (<1 ps from 0 V to VBR) and maintains stable performance across –55 °C to +175 °C operating junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 33.3 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 37.1 V / 47.0 V - Breakdown voltage range at 1 mA test current; defines turn-on threshold tolerance |
| VC @ IPPM | 53.9 V @ 11.1 A - Clamping voltage under 10/1000 µs surge; limits downstream voltage stress |
| PPK | 600 W - Peak pulse power handling capability; determines survivability against defined transient waveforms |
| TJ max | +175 °C - Maximum junction temperature; supports high-ambient automotive and industrial environments |
| IR @ VWM | <1 µA - Reverse leakage current; ensures minimal standby power loss and signal integrity |
| Response time | <1 ps - Time from 0 V to VBR; enables protection of high-speed digital and analog circuits |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking for unidirectional polarity. Lead finish: pure tin, solderable per J-STD-002. Weight: ~0.400 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33A | Same DO-214AA package; lower PPK (600 W same), but VC = 53.3 V @ 11.2 A; no AEC-Q101 listing | General industrial use only; not certified for automotive underhood environments | Select SMBJ33A only if AEC-Q101 qualification is not required and DO-214AA footprint is preferred |
| 1.5KE33A | Higher PPK (1500 W), larger DO-201AD package, slower response (~1 ns), VC = 53.3 V @ 28.3 A | Better for high-energy surges but unsuitable for space-constrained PCBs or fast-edge protection | Choose 1.5KE33A where surge energy exceeds 600 W and board area allows larger case |
Compared with SMBJ33A and 1.5KE33A, the BZW06-33H uniquely combines AEC-Q101 qualification, DO-204AC (DO-15) form factor, and sub-picosecond response-making it optimal for automotive lighting and compact industrial modules requiring certified reliability and fast clamping.

FAQ
What is the polarity configuration of the BZW06-33H?
The BZW06-33H is a unidirectional TVS diode, with cathode marked by a band on the DO-204AC (DO-15) package. It conducts only during reverse overvoltage events on the cathode side, making it suitable for DC rail protection where polarity is fixed. This differs from bidirectional variants like BZW06-33BH, which protect AC or floating signals.
Does the BZW06-33H meet AEC-Q101 requirements?
Yes, the "H" suffix in BZW06-33H explicitly denotes AEC-Q101 qualification. It has passed stress tests including high-temperature operating life, temperature cycling, and ESD per AEC-Q101 Rev D, confirming suitability for automotive underhood and cabin applications such as lighting control and body ECUs.
What is the maximum clamping voltage of the BZW06-33H under standard test conditions?
The BZW06-33H has a maximum clamping voltage (VC) of 53.9 V at 11.1 A under the 10/1000 µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and ensures downstream components see limited overvoltage during transient events.
Can the BZW06-33H be used in place of the BZW06-33 without modification?
No-the BZW06-33H is AEC-Q101 qualified and undergoes additional screening versus the standard BZW06-33. While electrically identical in VWM, VBR, and VC, the BZW06-33H includes enhanced process controls and lot-level qualification data required for automotive use; substituting requires revalidation per customer quality protocols.
What is the thermal resistance specification for the BZW06-33H?
The BZW06-33H has a junction-to-lead thermal resistance (RθJL) of 60 °C/W and junction-to-ambient resistance (RθJA) of 100 °C/W with 10 mm lead length. These values enable reliable operation up to 175 °C junction temperature when mounted with adequate copper pour and lead thermal relief.
