Product details
Overview
BZW06-23H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, with 23.1V working stand-off voltage (VWM), 25.7–28.4V breakdown voltage (VBR), and 37.5V clamping voltage (VC) at 16A peak pulse current (10/1000μs). It delivers AEC-Q101 qualification for automotive-grade surge protection in power supply rails and signal lines.
For engineers reviewing the BZW06-23H datasheet, BZW06-23H pinout, BZW06-23H application, or BZW06-23H equivalent, key selection criteria include its 1.7W steady-state power dissipation, <1μA reverse leakage at VWM, 60°C/W junction-to-lead thermal resistance, and fast sub-1ps response time from 0V to VBR - critical for ESD and EFT immunity in automotive ECUs and lighting drivers.
Technical Context
The BZW06-23H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 25.7–28.4V breakdown range at 1mA test current. Its low dynamic impedance ensures stable clamping during 600W transients (10/1000μs), while the DO-204AC package supports lead-free soldering per J-STD-002 and meets UL 94V-0 flammability rating.
AEC-Q101 qualification confirms robustness across -55°C to +175°C operating junction temperature, with 0.096%/°C VBR temperature coefficient enabling predictable performance under thermal stress. The device exhibits <1μA IR at 23.1V and 10MHz junction capacitance of ~200pF (typical), making it suitable for DC-biased protection without signal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 23.1 V - Maximum continuous reverse voltage before conduction begins; sets safe operating margin for 24V automotive systems. |
| VBR (min/typ/max) | 25.7 / 27.0 / 28.4 V @ 1 mA - Avalanche onset range defining turn-on threshold; tight tolerance enables precise overvoltage trip points. |
| VC @ IPPM | 37.5 V @ 16.0 A (10/1000μs) - Clamped voltage during surge; limits downstream IC stress to safe levels during load dump events. |
| PPK | 600 W - Peak pulse power handling; sustains high-energy transients like ISO 7637-2 Pulse 5a without failure. |
| IR @ VWM | <1 μA - Minimal leakage at rated stand-off voltage; preserves battery life and avoids false triggering in low-power circuits. |
| TJ max | +175 °C - Maximum junction temperature; supports under-hood placement in automotive modules with minimal derating. |
| RθJL | 60 °C/W - Junction-to-lead thermal resistance; enables effective heat transfer to PCB copper via leads, critical for reliability in sustained surge conditions. |
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 ≈0.400g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance return plane; carries full surge current during clamping. |
| Cathode | Reverse-biased terminal / Protected line connection | Connected to protected node (e.g., 24V rail); blocks normal operation but avalanches during overvoltage. |
Key Features
| Feature | Design Value |

Use Scenario: Shielding 4–20mA analog sensor outputs in factory automation systems from cable-induced surges and lightning-induced coupling. IC Role / Device Role / Timing Role: Bidirectional-capable variant not applicable; BZW06-23H used in DC-coupled unidirectional configuration on powered sensor lines. Use Value: Maintains signal integrity with <1μA leakage at 23.1V, while clamping 600W transients that would otherwise destroy precision op-amps or ADC front-ends. | Use Scenario: Adding secondary protection to RS-485 or LIN bus nodes exposed to human-body-model (HBM) ESD events in vehicle infotainment systems. IC Role / Device Role / Timing Role: Primary clamping element upstream of integrated bus transceiver ESD structures. Use Value: Reduces clamping voltage seen by transceiver from >60V to ≤37.5V, lowering risk of permanent latch-up or functional interruption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Same DO-214AA package; 24V VWM, 38.9V VC @ 15.4A; 600W rating; no AEC-Q101 qualification stated in standard datasheet. | Designed for industrial/commercial use; lacks automotive qualification evidence and tighter VBR tolerance (26.7–29.5V vs. 25.7–28.4V). | Select SMBJ24A only if AEC-Q101 is not required and board space allows SMB package; verify thermal performance with RθJA = 40°C/W (vs. BZW06-23H's 100°C/W). |
| P6KE27A | DO-204AL (DO-41) package; 27V VWM, 41.5V VC @ 14.5A; same 600W rating; no AEC-Q101 qualification; higher VBR spread (30–33V). | Legacy through-hole alternative; larger footprint and lower thermal efficiency due to higher RθJL (75°C/W) and heavier weight (0.55g). | Choose P6KE27A only for legacy through-hole designs where DO-15 footprint compatibility is not needed; avoid in new automotive designs requiring AEC-Q101. |
Compared with SMBJ24A and P6KE27A, the BZW06-23H offers verified AEC-Q101 compliance, tighter VBR tolerance, and DO-15 packaging optimized for automated axial insertion - delivering superior reliability in automotive power rails where thermal management and qualification traceability are mandatory.

FAQ
What is the AEC-Q101 qualification status of the BZW06-23H?
The BZW06-23H is explicitly AEC-Q101 qualified per the manufacturer's documentation, confirming its suitability for automotive applications including engine control, body electronics, and ADAS subsystems. This qualification covers temperature cycling, humidity bias, mechanical shock, and high-temperature operating life testing - all validated for the BZW06-23H lot release process.
How does the BZW06-23H differ from the non-H suffix variant BZW06-23?
The "H" suffix in BZW06-23H denotes full AEC-Q101 qualification, whereas BZW06-23 is the commercial-grade version without automotive qualification testing. Both share identical electrical parameters (VWM = 23.1V, VBR = 25.7–28.4V, VC = 37.5V), but only BZW06-23H carries certified test reports and lot-level traceability required for Tier 1 automotive supply chains.
What is the maximum peak pulse current the BZW06-23H can handle at 10/1000μs?
The BZW06-23H handles 16.0 A peak pulse current (IPPM) under the 10/1000μs waveform while maintaining a clamping voltage of 37.5 V. This corresponds to its rated 600W peak pulse power (PPK), verified per Fig.3 in the official datasheet and consistent across production lots.
Is the BZW06-23H unidirectional or bidirectional, and how is polarity marked?
The BZW06-23H is a unidirectional TVS diode, indicated by the absence of "B" suffix (e.g., BZW06-23B is bidirectional). Polarity is marked by a cathode band on the DO-204AC (DO-15) package body - the banded end connects to the protected line, while the anode connects to ground or return path.
What is the thermal resistance profile of the BZW06-23H, and how does it impact PCB layout?
The BZW06-23H has RθJL = 60°C/W (junction-to-lead) and RθJA = 100°C/W (junction-to-ambient, L = 10mm). For optimal thermal performance, PCB traces connected to both leads should be ≥1.5 mm wide and thermally coupled to internal ground planes; excessive trace length or narrow routing increases effective RθJA and risks thermal runaway during repetitive surges.
