Product details
Overview
BZW06-299BH 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 inductive load surge protection in power supply rails and signal lines.
For engineers reviewing the BZW06-299BH datasheet, BZW06-299BH pinout, BZW06-299BH application, or BZW06-299BH equivalent, this AEC-Q101 qualified DO-15 device offers verified clamping performance, low dynamic impedance, sub-1ps response time, <1μA leakage above 10V, and thermal robustness to 175°C junction temperature - critical for automotive lighting, infotainment power inputs, and industrial control I/O protection.
Technical Context
The BZW06-299BH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 350V nominal breakdown (VBR), clamping transients to ≤482V at 1.6A peak pulse current under 10/1000μs waveform. Its DO-204AC (DO-15) package supports lead-free soldering and meets JESD201 Class 2 whisker resistance.
It delivers 600W non-repetitive peak pulse power with thermal resistance RθJL = 60°C/W and RθJA = 100°C/W, enabling reliable operation across -55°C to +175°C junction temperature range while maintaining <1μA reverse leakage at 299V (VWM).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ280A | DO-214AA package, 280V VWM, 311V VBR, 457V VC @ 1.3A, 600W rating | Surface-mount alternative; lower clamping but smaller footprint; no AEC-Q101 qualification | Select when board space is constrained and automotive qualification is not required |
| 1.5KE270A | DO-201AD package, 270V VWM, 300V VBR, 432V VC @ 1.4A, 1500W rating | Higher power rating but larger package; higher leakage (~5μA); no AEC-Q101 or halogen-free certification | Select only for non-automotive, high-energy surge environments where size is secondary |
Compared with SMBJ280A and 1.5KE270A, the BZW06-299BH provides AEC-Q101 validation, tighter leakage (<1μA), halogen-free construction, and optimized clamping for 24–48V automotive and industrial rails - making it the preferred choice where reliability, regulatory compliance, and thermal stability are prioritized over footprint or raw power rating.

FAQ
What is the polarity configuration of the BZW06-299BH?
The BZW06-299BH is a unidirectional TVS diode, with cathode marked by a band on the DO-15 body. It conducts in reverse bias above VBR and blocks forward current like a standard diode. This configuration is used for DC rail protection where polarity is fixed, such as 24V automotive power inputs. The BZW06-299BH must be oriented with cathode toward the protected line and anode to ground.
Does the BZW06-299BH meet AEC-Q101 requirements?
Yes, the "H" suffix in BZW06-299BH explicitly denotes AEC-Q101 qualification. It has passed stress tests including high-temperature operating life, temperature cycling, ESD (HBM ≥8kV), and mechanical shock - all per AEC-Q101 Rev D. This makes the BZW06-299BH suitable for automotive powertrain, chassis, and body electronics where component reliability is mission-critical.
What is the maximum clamping voltage of the BZW06-299BH under standard test conditions?
The BZW06-299BH has a maximum clamping voltage (VC) of 482 V at 1.6 A peak pulse current using the 10/1000μs waveform. This value is measured per JEDEC standards and represents the upper limit of voltage seen by downstream circuitry during a standardized surge event - a key parameter for ensuring protected ICs remain within absolute maximum ratings.
Can the BZW06-299BH be used in bidirectional signal line protection?
No, the BZW06-299BH is unidirectional only. For bidirectional AC or data-line protection, use the BZW06-299BH's counterpart BZW06-299B, which features symmetrical breakdown in both directions. Using the BZW06-299BH on AC signals risks forward conduction and failure; always verify polarity and signal swing before selecting the BZW06-299BH.
What is the thermal resistance and maximum junction temperature of the BZW06-299BH?
The BZW06-299BH has a junction-to-lead thermal resistance (RθJL) of 60°C/W and junction-to-ambient (RθJA) of 100°C/W with 10mm lead length. Its maximum rated junction temperature is +175°C, allowing operation in under-hood automotive environments and sealed industrial enclosures without forced cooling - provided PCB copper area and airflow meet minimum layout guidelines specified in the BZW06-299BH datasheet.
