Product details
Overview
BZW06-299H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode with a 299V working stand-off voltage, 350V nominal breakdown voltage, and 482V clamping voltage at 1.6A (10/1000μs), designed for automotive-grade ESD and surge protection in power rails and signal lines.
For engineers reviewing the BZW06-299H datasheet, BZW06-299H pinout, BZW06-299H application, or BZW06-299H equivalent, key selection criteria include AEC-Q101 qualification, DO-204AC package compatibility, low dynamic impedance, sub-1ps response time, and verified clamping performance under IEC 61000-4-5 surge conditions.
Technical Context
The BZW06-299H operates as a unidirectional avalanche diode, triggering at 350V (typ.) to clamp transients while maintaining <1μA leakage above 299V. Its junction-to-lead thermal resistance of 60°C/W supports reliable power dissipation during repetitive 1ms surges up to 600W.
Designed for automotive environments, it meets AEC-Q101 stress requirements including temperature cycling, humidity bias, and mechanical shock. The device exhibits a positive temperature coefficient of 0.110%/°C for VBR, enabling predictable voltage drift across –55°C to +175°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 299 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/typ/max) | 332 / 350 / 368 V - Breakdown voltage range at 1mA test current; defines turn-on threshold consistency |
| VC @ IPPM (10/1000μs) | 482 V at 1.6 A - Clamped voltage during standard lightning surge; determines protected circuit's peak stress level |
| PPK | 600 W - Peak pulse power handling per single 1ms transient; validates robustness against IEC 61000-4-5 Level 4 |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive locations |
| RθJL | 60 °C/W - Junction-to-lead thermal resistance; confirms effective heat transfer to PCB copper via leads |
| IR @ VWM | <1 μA - Reverse leakage at rated stand-off voltage; ensures minimal standby power loss |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking for unidirectional polarity. Leads are pure tin-plated and solderable per J-STD-002.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24V CAN bus power supply against load dump and alternator transients in vehicle ECUs. IC Role / Device Role / Timing Role: Primary clamping element on main power input, placed upstream of DC/DC converters and LDOs. Use Value: Limits voltage to ≤482V during 10/1000μs 600W surges, preventing damage to downstream PMICs and microcontrollers. | Use Scenario: Safeguarding analog sensor inputs (e.g., pressure, temperature) in PLC modules exposed to EFT noise. IC Role / Device Role / Timing Role: Low-capacitance TVS placed at connector entry point to shunt fast transients before signal conditioning circuitry. Use Value: Sub-1ps response ensures clamping occurs before EFT edges (<5ns rise time) propagate into op-amp front-ends. |
| LED Driver Overvoltage Protection | ESD-Sensitive Communication Port Protection |
Use Scenario: Preventing catastrophic failure of constant-current LED drivers due to inductive switching spikes from relay coils. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output terminals to absorb stored inductive energy. Use Value: 600W rating handles 100A+ peak currents from 8.3ms half-sine surges (IFSM = 100A), avoiding thermal runaway. | Use Scenario: Shielding RS-485 transceiver pins from ±8kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Unidirectional TVS on VCC and signal lines to clamp ESD-induced overvoltage without affecting DC bias. Use Value: <1μA leakage at 299V ensures no loading on 3.3V/5V bias networks; AEC-Q101 grade adds reliability margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ280A | 280V VWM, 311V VBR (min), 457V VC @ 1.3A; same DO-214AA package but lower power (600W identical) | Lower clamping voltage ideal for 28V systems; lacks AEC-Q101 qualification | Select when AEC-Q101 is not required and tighter clamping at lower voltage is prioritized |
| P6SMB330A | 330V VWM, 367V VBR (min), 530V VC @ 1.1A; same DO-214AA package, 600W rating, AEC-Q101 qualified | Higher VWM/VBR better suited for 300–350V industrial DC links; clamps ~48V higher than BZW06-299H | Choose for higher-voltage DC bus protection where 482V clamping is insufficient |
Compared with SMBJ280A and P6SMB330A, the BZW06-299H uniquely balances 299V system compatibility, AEC-Q101 compliance, and 482V clamping-making it optimal for 24V/36V automotive power domains requiring certified reliability and precise voltage coordination.

FAQ
What is the maximum clamping voltage of the BZW06-299H under a 10/1000μs surge?
The BZW06-299H has a maximum clamping voltage (VC) of 482 V at 1.6 A under the standardized 10/1000μs waveform. This value is measured per JEDEC standards and reflects the peak voltage seen by downstream circuitry during worst-case transient events-critical for ensuring protected ICs remain within absolute maximum ratings. The BZW06-299H maintains this clamping performance across its full operating temperature range.
Is the BZW06-299H suitable for bidirectional signal line protection?
No, the BZW06-299H is a unidirectional TVS diode, indicated by the absence of "B" suffix and presence of cathode band marking. It conducts only during reverse overvoltage conditions and blocks forward current. For bidirectional protection (e.g., RS-485 data lines), the BZW06-299B variant must be used. Using BZW06-299H on AC-coupled or symmetrical signal paths risks improper clamping or forward conduction.
Does the BZW06-299H meet AEC-Q101 requirements for automotive use?
Yes, the "H" suffix in BZW06-299H explicitly denotes AEC-Q101 qualification. It has passed all required stress tests-including high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and mechanical shock-per AEC-Q101 Rev D. This certification validates its suitability for under-hood and body-control module applications where reliability under thermal and vibration stress is mandatory.
What is the thermal resistance from junction to ambient for the BZW06-299H in standard mounting?
The BZW06-299H has a junction-to-ambient thermal resistance (RθJA) of 100°C/W when mounted with 10mm lead length, per standard JEDEC test conditions. This value assumes minimal PCB copper area; actual RθJA improves significantly with ≥1 cm² of 2-oz copper connected to both leads. For sustained surge duty cycles, junction temperature must stay below +175°C-requiring derating above +75°C ambient per the published pulse derating curve.
How does the temperature coefficient affect the breakdown voltage of the BZW06-299H?
The BZW06-299H has a VBR temperature coefficient of +0.110%/°C. At +125°C ambient, its nominal 350V breakdown increases by approximately 3.85V (350 × 0.0011 × 100), shifting to ~353.9V. This positive drift ensures safer margin against false triggering at high temperatures and aligns with automotive thermal profiles where voltage references must remain stable across wide operating ranges.
