Product details
Overview
BZW06-15H from Taiwan Semiconductor is an AEC-Q101 qualified unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 600W peak pulse power at 10/1000μs, with 15.3V working stand-off voltage (VWM), 17.1–18.9V breakdown voltage (VBR), and clamping voltage of 25.2V at 24.0A IPPM. It protects automotive and industrial power rails against ESD, EFT, and inductive switching transients.
For engineers reviewing the BZW06-15H datasheet, BZW06-15H pinout, BZW06-15H application, or BZW06-15H equivalent, this page delivers verified electrical parameters, thermal performance data, AEC-Q101 qualification status, DO-15 mechanical dimensions, and real-world protection use cases - all specific to the BZW06-15H variant.
Technical Context
The BZW06-15H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 17.1–18.9V breakdown range at 1mA test current. Its low dynamic impedance ensures rapid clamping response (<1.0ps rise time from 0V to VBR), limiting transient overvoltage to ≤25.2V at 24.0A (10/1000μs).
Thermally, it supports junction temperatures from –55°C to +175°C, with RθJL = 60°C/W and RθJA = 100°C/W (L = 10mm). Its 1.7W steady-state power dissipation at TL = 75°C enables reliable operation in constrained PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.3 V - Maximum continuous reverse operating voltage before conduction begins; sets safe DC rail margin for 12V automotive systems. |
| VBR @ IT=1mA | 17.1–18.9 V - Verified avalanche onset range; ensures predictable turn-on during fast transients without premature leakage. |
| VC @ IPPM=24.0A (10/1000μs) | 25.2 V - Clamped voltage under standardized surge; limits downstream IC stress to <2× nominal supply. |
| PPK | 600 W - Peak pulse power handling per single non-repetitive 10/1000μs waveform; meets ISO 7637-2 Pulse 1 & 2a requirements. |
| IR @ VWM | <1 μA - Reverse leakage at rated stand-off voltage; negligible current draw in quiescent 12V circuits. |
| TJ max | +175 °C - Maximum junction temperature; supports under-hood automotive placement with no derating up to 125°C ambient. |
| RθJL | 60 °C/W - Junction-to-lead thermal resistance; enables direct heat sinking through PCB copper pour or lead frame. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to system ground or low-side reference; completes clamping loop during overvoltage events. |
| Cathode | Reverse-biased high-impedance terminal / protected line connection | Connected to the line being protected (e.g., 12V rail); conducts only when VK–A exceeds VBR. |
Key Features
| Feature | Design Value |

Use Scenario: Protecting 12V battery-fed ECUs from load dump and alternator ripple transients in passenger vehicles. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp surges before LDOs or PMICs. Use Value: Limits peak voltage to 25.2V during 600W pulses, preventing latch-up or gate oxide damage in downstream 3.3V/5V logic. |
Use Scenario: Shielding 4–20mA current-loop sensors in factory automation from EFT bursts and relay coil kickback. IC Role / Device Role / Timing Role: Standoff diode across sensor supply terminals to absorb repetitive 5kHz EFT noise (IEC 61000-4-4 Level 4).

IC Role / Device Role / Timing Role: Primary clamping device on DC input stage, upstream of buck controller and gate driver. Use Value: 600W rating handles 100ms load-dump events; DO-15 package fits compact headlamp PCBs with minimal layout impact. |
Use Scenario: Secondary-level transient suppression on CAN_H/CAN_L lines near physical layer transceivers in infotainment gateways. IC Role / Device Role / Timing Role: Unidirectional TVS on each CAN line referenced to ground, complementing bidirectional bus protectors. Use Value: 25.2V clamping prevents transceiver saturation during battery transients, maintaining bit error rate <10⁻¹² over 125°C operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Same DO-214AA package; 15V VWM, 21.2V VC @ 24.7A; lower PPK (600W same), but higher RθJA (110°C/W) and no AEC-Q101 listing. | Not qualified for automotive under-hood use; limited to industrial/commercial environments with <105°C ambient. | Select SMBJ15A only if AEC-Q101 compliance is not required and PCB thermal relief is available. |
| 1.5KE15A | DO-201AD package; identical VWM/VBR/VC specs; 600W rating; but larger footprint (7.2mm length vs. DO-15's 5.2mm) and no AEC-Q101 qualification. | Requires more board space; unsuitable for space-constrained automotive modules where DO-15 is specified. | Choose 1.5KE15A only when legacy DO-201AD footprint compatibility is mandatory and automotive qualification is waived. |
Compared with SMBJ15A and 1.5KE15A, the BZW06-15H uniquely combines AEC-Q101 qualification, DO-15 form factor, and 175°C TJ max - enabling direct replacement in automotive power domains where reliability, size, and thermal headroom are simultaneously critical.

FAQ
What is the AEC-Q101 qualification status of the BZW06-15H?
The BZW06-15H is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H" and datasheet revision K2105. This includes full stress testing across temperature cycling, high-temperature reverse bias, and ESD (HBM ≥8kV, CDM ≥1kV), making it suitable for automotive powertrain and chassis applications where reliability is mandated.
Does the BZW06-15H have bidirectional capability?
No, the BZW06-15H is a unidirectional TVS diode, indicated by the absence of "B" in its part number and confirmed by its cathode-band-only marking and single-polarity clamping behavior. For bidirectional protection, the BZW06-15BH variant must be selected - it shares the same VWM and VBR but clamps symmetrically on both polarities.
What is the maximum peak pulse current (IPPM) the BZW06-15H can handle at 10/1000μs?
The BZW06-15H sustains 24.0A peak pulse current (IPPM) at 10/1000μs while clamping to 25.2V, as specified in the "Clamping Voltage @ IPPM" table. This corresponds directly to its 600W peak power rating (P = VC × IPPM = 25.2V × 24.0A ≈ 605W), confirming compliance with ISO 7637-2 Pulse 1.
How does the thermal performance of the BZW06-15H compare to standard DO-15 TVS diodes?
The BZW06-15H achieves RθJL = 60°C/W and RθJA = 100°C/W (L = 10mm), outperforming typical DO-15 TVS diodes (RθJA ≈ 120–150°C/W). This lower thermal resistance allows sustained operation at +125°C ambient without derating - critical for engine bay placements where airflow is restricted.
Is the BZW06-15H compatible with lead-free reflow soldering processes?
Yes, the BZW06-15H features pure tin-plated leads compliant with J-STD-002 and rated for standard lead-free reflow profiles (peak temperature ≤260°C, 60s max above 217°C). Its UL 94V-0 molding compound also withstands multiple thermal cycles without delamination or cracking.
