Product details
Overview
BZW06-26BH from Taiwan Semiconductor is a unidirectional 600W Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, with 25.6V working stand-off voltage, 28.5–31.5V breakdown voltage at 1mA, and 41.5V clamping voltage at 14.5A (10/1000μs). It delivers AEC-Q101 qualification for automotive-grade surge protection in power supply rails and interface lines.
For engineers reviewing the BZW06-26BH datasheet, BZW06-26BH pinout, BZW06-26BH application, or BZW06-26BH equivalent, key selection criteria include its 600W peak pulse power rating, low dynamic impedance, sub-1ps response time (unidirectional), <1μA reverse leakage above 10V, and AEC-Q101 qualification-critical for automotive ESD and load-dump immunity design.
Technical Context
The BZW06-26BH operates as a unidirectional avalanche diode, triggered when transient voltage exceeds its 28.5V minimum breakdown threshold. Its clamping action limits downstream circuit voltage to ≤41.5V under 14.5A 10/1000μs surge, with junction-to-lead thermal resistance of 60°C/W enabling reliable power dissipation during repetitive transients.
Designed for single-polarity DC line protection, it features pure tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and meets JESD201 Class 2 whisker resistance. Polarity is marked by cathode band; operating junction temperature spans –55°C to +175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 25.6 V - Maximum continuous reverse voltage before conduction begins; defines safe operating DC bias level |
| VBR (min–max) | 28.5–31.5 V @ 1 mA - Avalanche onset range; ensures predictable turn-on across temperature and unit variation |
| VC @ IPPM | 41.5 V @ 14.5 A (10/1000μs) - Clamped voltage during worst-case surge; determines maximum stress on protected IC |
| PPK | 600 W - Peak pulse power handling capability; supports high-energy transients like ISO 7637-2 Load Dump Pulse 5a |
| IR @ VWM | <1 μA - Negligible leakage current at rated stand-off; avoids power loss or false triggering in low-current systems |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments |
| RθJL | 60 °C/W - Thermal resistance from junction to lead; informs heatsinking requirements for sustained surge duty cycles |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking for unidirectional polarity. Lead length 9.5 mm, weight ≈0.400 g, RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage rail; completes conduction path during reverse-biased surge event |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 24V supply); avalanche conduction occurs when voltage exceeds VBR relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and ADAS power domains |
| 600W peak pulse power | Withstands ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 Combination Wave surges without degradation |
| Sub-1ps response time (unidirectional) | Clamps transients before sensitive logic or analog circuitry can be damaged-critical for CAN/LIN bus protection |
| Low dynamic impedance | Ensures minimal voltage overshoot during fast-rising ESD events (e.g., IEC 61000-4-2 ±8kV contact discharge) |
| UL 94V-0 flammability rating | Molding compound self-extinguishes under flame exposure-required for under-hood and cabin-mounted modules |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24V supply inputs in engine control modules against load dump transients up to 60V for 400ms. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery rail and DC-DC converter input. Use Value: Limits voltage to ≤41.5V during 14.5A surge, preventing overvoltage failure of downstream regulators and microcontrollers. | Use Scenario: Shielding 4–20mA current-loop sensor interfaces from ESD and cable-induced surges in factory automation PLCs. IC Role / Device Role / Timing Role: Bidirectional-capable series (BZW06-26B) used; this unidirectional variant applied where polarity is fixed and ground-referenced. Use Value: Sub-1ps response ensures clamping before transients couple into precision op-amp front-ends or ADC reference paths. |
| LED Lighting Driver Protection | Automotive LIN Bus Line Protection |
Use Scenario: Safeguarding constant-current LED drivers in headlamp modules from inductive switching spikes generated by relay coils. IC Role / Device Role / Timing Role: TVS placed across driver output terminals to absorb flyback energy. Use Value: 600W rating handles repetitive 100A+ coil turn-off spikes without parametric shift or thermal runaway. | Use Scenario: Protecting LIN transceiver pins (e.g., TJA1020) from ESD and electrical fast transients in door module networks. IC Role / Device Role / Timing Role: Unidirectional TVS connected between LIN line and ground, leveraging low capacitance and fast response. Use Value: Clamping voltage ≤41.5V keeps LIN signal integrity intact during ±8kV ESD events per ISO 10605. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ26A | Same DO-214AA package; 26V VWM, 42.1V VC @ 14.3A; no AEC-Q101 qualification | General industrial use only; not approved for automotive safety-critical nodes | Select SMBJ26A only if AEC-Q101 is not required and board space allows larger SMB footprint |
| P6KE27A | DO-15 package; 27V VWM, 43.0V VC @ 13.9A; 600W rating; no AEC-Q101 | Limited to non-automotive applications due to lack of automotive qualification and higher leakage (≤5μA) | Prefer P6KE27A only for cost-sensitive consumer or white-goods designs where AEC-Q101 is irrelevant |
Compared with SMBJ26A and P6KE27A, the BZW06-26BH provides verified AEC-Q101 compliance, lower leakage (<1μA), and tighter VBR tolerance (28.5–31.5V vs. typical ±5%), making it the sole choice for automotive power domain protection where reliability and specification margin are mandatory.

FAQ
What does the "H" suffix in BZW06-26BH signify?
The "H" suffix in BZW06-26BH indicates full AEC-Q101 qualification, confirming that the device has passed stress tests for automotive-grade reliability-including temperature cycling, humidity testing, and mechanical shock. This certification is essential for deployment in engine control, chassis, and body electronics where failure is not acceptable. The BZW06-26BH is tested per AEC-Q101 Rev D, unlike standard BZW06-26 variants.
How does BZW06-26BH differ from BZW06-26B?
The BZW06-26BH is the AEC-Q101-qualified unidirectional version, while BZW06-26B is the bidirectional variant without automotive qualification. Their electrical parameters (VWM, VBR, VC) are identical, but BZW06-26BH undergoes additional qualification testing, uses traceable lot controls, and carries stricter process controls. BZW06-26BH also features green compound and specific date coding per automotive standards.
Can BZW06-26BH be used in bidirectional signal lines like CAN or LIN?
No-BZW06-26BH is unidirectional and must be used only on DC-biased lines referenced to ground (e.g., 24V supply rails). For bidirectional data lines such as CAN or LIN, the BZW06-26B variant is required. Using BZW06-26BH on a bidirectional line would cause forward conduction during negative transients, potentially damaging the protected IC or disrupting communication.
What is the maximum surge current BZW06-26BH can handle at 8/20μs waveform?
Per the datasheet, BZW06-26BH clamps to 53.5V at 75A under the 8/20μs waveform. This corresponds to a peak pulse power of 600W, consistent with its rating. Engineers should verify PCB layout thermal relief and trace width to sustain 75A for ≤20μs without fusing or solder joint failure-especially critical in automotive under-hood environments.
Is BZW06-26BH compatible with lead-free reflow soldering processes?
Yes-BZW06-26BH features pure tin-plated leads compliant with J-STD-002 and rated for standard lead-free reflow profiles (peak temperature ≤260°C, 60–90 seconds above 217°C). Its UL 94V-0 epoxy compound withstands multiple reflow cycles without delamination or cracking, supporting automated SMT assembly in high-volume automotive manufacturing.
