Product details
Overview
BZW04-188BHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 188 V standoff voltage (VWM), 209–231 V breakdown voltage (VBR) at 1 mA, 301 V maximum clamping voltage (VC) at 1.4 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and industrial I/O circuits from ESD and inductive switching surges.
For engineers reviewing the BZW04-188BHE3/54 datasheet, BZW04-188BHE3/54 pinout, BZW04-188BHE3/54 application, or BZW04-188BHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, clamping performance under standardized surge waveforms, and direct alternatives for automotive and industrial transient protection design.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR min/max (209–231 V), VC (301 V), and IPPM (1.4 A) specifications in either direction. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low incremental surge resistance for consistent clamping behavior across temperature.
The device complies with AEC-Q101 for automotive-grade reliability and supports repetitive 10/1000 μs surge events at 0.01% duty cycle. Its 175 °C max junction temperature and DO-41 package enable use in high-ambient environments without derating below 75 °C lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 188 V - maximum continuous reverse working voltage before clamping initiates |
| VBR (min/max) | 209 V / 231 V at 1 mA - precise breakdown threshold defining turn-on sensitivity |
| VC @ IPPM | 301 V at 1.4 A - clamped voltage during 10/1000 μs surge, limiting stress on downstream ICs |
| PPPM | 400 W - peak transient energy absorption capability per IEC 61000-4-5 standard waveform |
| ID @ VWM | <1.0 μA - ultra-low leakage preserves signal integrity in high-impedance sensor lines |

IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and chassis ground, responding within <1 ns to limit voltage excursion. Use Value: Maintains signal fidelity below 301 V clamp while surviving repeated 12 V/24 V system transients - critical for ASIL-B functional safety compliance. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to inductive kickback from solenoid valves and relay coils. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing >400 W surge energy before upstream optocouplers or microcontrollers are stressed. Use Value: Enables >100,000 actuation cycles without degradation, verified by AEC-Q101 temperature cycling and HTRB tests. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding RS-485 transceivers and Ethernet PHYs in base stations from lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: First-line transient suppressor at connector entry point, shunting energy before common-mode chokes and data ICs. Use Value: Achieves <301 V clamping at 1.4 A - sufficient to prevent latch-up in 3.3 V/5 V interface ICs per IEC 61000-4-5 Ed. 3 test criteria. | Use Scenario: Protecting gate drivers and MCU GPIOs in washing machine motor inverters from back-EMF spikes during brushless DC motor commutation. IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF) bidirectional clamp across half-bridge power rails and control signals. Use Value: Prevents false triggering of overvoltage protection circuits while sustaining 175 °C junction temperature during continuous 60 °C ambient 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 |
|---|---|---|---|
| SMBJ188CA | DO-214AA package; 188 V VWM; 301 V VC; 400 W PPPM - same electrical specs but surface-mount | Requires PCB re-layout for SMD placement; better high-frequency response due to lower parasitic inductance | Select when board space is constrained and automated assembly is preferred over through-hole |
| P6KE188CA | DO-15 package; 188 V VWM; 301 V VC; 600 W PPPM - higher power rating but larger footprint and slower response | Higher surge margin for infrequent high-energy events; not AEC-Q101 qualified | Select for cost-sensitive industrial equipment where automotive qualification is unnecessary |
Compared with BZW04-188BHE3/54, SMBJ188CA offers identical clamping performance in a compact SMD form factor ideal for dense layouts, while P6KE188CA provides greater single-pulse energy headroom in a legacy through-hole package lacking automotive qualification - making BZW04-188BHE3/54 the optimal choice for AEC-Q101–mandated designs requiring proven reliability in DO-41 format.

FAQ
What is the clamping voltage of BZW04-188BHE3/54 under a 10/1000 μs surge?
The BZW04-188BHE3/54 exhibits a maximum clamping voltage (VC) of 301 V when subjected to its rated peak pulse current (IPPM) of 1.4 A using the standardized 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and ensures downstream components remain below destructive voltage thresholds during transient events. The BZW04-188BHE3/54 maintains this clamping performance bidirectionally and across its full operating temperature range.
Is BZW04-188BHE3/54 qualified for automotive applications?
Yes, BZW04-188BHE3/54 carries the HE3 suffix, indicating it is RoHS-compliant and AEC-Q101 qualified. It has passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT) per AEC-Q101 Rev D. This makes BZW04-188BHE3/54 suitable for automotive powertrain, body electronics, and ADAS sensor protection where zero field failure is mandated.
What does the "B" suffix in BZW04-188BHE3/54 signify?
The "B" suffix in BZW04-188BHE3/54 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both forward and reverse polarities, with identical VBR (209–231 V), VC (301 V), and IPPM (1.4 A) characteristics regardless of voltage polarity. Unlike unidirectional variants, BZW04-188BHE3/54 has no cathode marking and is used where AC-coupled or differential signal lines require equal protection in both directions.
What is the maximum reverse leakage current for BZW04-188BHE3/54 at its standoff voltage?
At its 188 V standoff voltage (VWM), the BZW04-188BHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor circuits and ensures minimal power loss in always-on automotive modules. Leakage remains within specification up to +125 °C, with typical values well below 0.5 μA under nominal operating conditions.
What packaging format is used for BZW04-188BHE3/54?
BZW04-188BHE3/54 is supplied in 13-inch diameter paper tape and reel packaging with a base quantity of 550 units per reel (package code "54"). The DO-41 (DO-204AL) axial-leaded package features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 class 2 whisker resistance, enabling reliable through-hole assembly and manual rework.
