Product details
Overview
BZW06-188BH from Taiwan Semiconductor is a unidirectional 600W Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, with 188V working stand-off voltage (VWM), 209–231V breakdown voltage (VBR), and 301V clamping voltage (VC) at 2.0A IPPM under 10/1000μs waveform-designed for automotive-grade ESD and inductive load surge protection in lighting control and power supply front-ends.
For engineers reviewing the BZW06-188BH datasheet, BZW06-188BH pinout, BZW06-188BH application, or BZW06-188BH equivalent, key selection criteria include AEC-Q101 qualification, low dynamic impedance, sub-1ps response time (unidirectional), <1μA reverse leakage above 10V, and thermal robustness up to TJ = +175°C in high-reliability vehicle subsystems.
Technical Context
The BZW06-188BH operates as a unidirectional avalanche diode, triggered when transient voltage exceeds its 209–231V VBR range at 1mA IT, clamping downstream circuitry to ≤301V at 2.0A peak pulse current. Its junction-to-lead thermal resistance (RθJL = 60°C/W) supports sustained surge handling under lead-temperature-limited conditions.
Designed for single-polarity transients, it features polarity marking (cathode band), pure tin-plated leads compliant with J-STD-002, and meets JESD201 Class 2 whisker resistance. It does not support bidirectional operation-BZW06-188B is the corresponding bidirectional variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 188 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 209 V / 231 V at 1 mA - Confirmed avalanche onset range for reliable overvoltage triggering |
| VC @ IPPM | 301 V at 2.0 A (10/1000μs) - Clamped voltage level protecting downstream ICs from destructive overshoot |
| PPK | 600 W - Peak pulse power rating defining single-event surge energy absorption capability |
| TJ max | +175 °C - Maximum junction temperature enabling operation in under-hood automotive environments |
| IR @ VWM | <1 μA - Negligible leakage current preserving system standby power integrity |
| Response time | <1.0 ps - Near-instantaneous turn-on for ESD and fast-rising transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ188A | Same VWM (188V), but 600W rating at 10/1000μs; SMB package (smaller footprint, higher RθJA) | Preferred for space-constrained PCBs; lower thermal mass limits repetitive surge duty cycle | Select SMBJ188A only if board layout allows SMC/SMB footprint and thermal management supports higher RθJA (140°C/W vs. BZW06-188BH's 100°C/W) |
| P6SMB188A | Identical electrical specs and DO-214AA (SMB) package; RoHS-compliant but not AEC-Q101 qualified | Acceptable for industrial/commercial use where automotive qualification is not required | Choose P6SMB188A for cost-sensitive non-automotive designs; avoid where AEC-Q101 validation is mandatory |
Compared with SMBJ188A and P6SMB188A, the BZW06-188BH provides verified AEC-Q101 qualification, DO-15 mechanical robustness for high-vibration environments, and lower RθJL (60°C/W) for improved surge power dissipation into leads-making it the preferred choice for under-hood automotive modules requiring long-term reliability.

FAQ
What is the clamping voltage of the BZW06-188BH at 2.0A peak pulse current?
The BZW06-188BH has a maximum clamping voltage (VC) of 301 V at 2.0 A peak pulse current under the 10/1000μs waveform. This value is measured per standard IEC 61000-4-5 test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The BZW06-188BH maintains this clamping performance consistently due to its low dynamic impedance and AEC-Q101-validated construction.
Is the BZW06-188BH suitable for bidirectional transient suppression?
No, the BZW06-188BH is a unidirectional TVS diode, indicated by its single cathode band marking and specified VBR/VWM parameters for reverse-biased operation only. For bidirectional protection, the BZW06-188B variant must be used. The BZW06-188BH will not conduct or clamp in forward direction beyond its ~1.2V forward voltage drop, making it unsuitable for AC-line or symmetrical transient scenarios.
Does the BZW06-188BH meet automotive qualification standards?
Yes, the "H" suffix in BZW06-188BH explicitly denotes AEC-Q101 qualification. This includes testing for high-temperature reverse bias (HTRB), temperature cycling, mechanical shock, and ESD per JESD22 standards. The BZW06-188BH is approved for use in automotive powertrain, body, and lighting modules where component-level reliability validation is mandatory.
What is the thermal resistance from junction to ambient for the BZW06-188BH?
The BZW06-188BH has a typical junction-to-ambient thermal resistance (RθJA) of 100°C/W when mounted on a standard FR-4 PCB with 10 mm lead length. This value assumes natural convection cooling and informs thermal derating curves-e.g., at 75°C ambient, the device must be derated to ~50% of its 600W peak rating. Its lower junction-to-lead resistance (RθJL = 60°C/W) supports heat transfer into copper traces or heatsinking leads.
How does the BZW06-188BH compare to standard DO-15 Zener diodes in surge protection?
Unlike general-purpose Zener diodes, the BZW06-188BH is engineered specifically for transient suppression: it delivers 600W peak power handling (vs. typically <5W for Zeners), sub-1ps response time, and tightly controlled clamping characteristics. Standard Zeners exhibit higher dynamic impedance and inconsistent VZ tolerance under surge conditions-whereas the BZW06-188BH guarantees VC ≤301V at 2.0A, making it a purpose-built solution for ISO 7637-2 and IEC 61000-4-5 compliance testing.
