Product details
Overview
BZW04-53BHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of signal and power lines. It features a 53 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1 mA, 400 W peak pulse power (10/1000 µs), and clamps transients to ≤85 V at 4.7 A peak pulse current - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04-53BHE3/54 datasheet, BZW04-53BHE3/54 pinout, BZW04-53BHE3/54 application, or BZW04-53BHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical data, clamping performance under standardized surge waveforms, and direct alternatives with documented parameter divergence.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VC, and IPPM specifications in positive and negative directions. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and low incremental surge resistance, enabling precise clamping without polarity-dependent behavior.
Rated for 175 °C maximum junction temperature and qualified to AEC-Q101, the device sustains repetitive 10/1000 µs surges at 0.01% duty cycle while maintaining thermal stability on standard PCB copper. The DO-41 package supports manual or automated insertion and meets UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1 mA - Confirmed bidirectional breakdown range; ensures predictable turn-on during transient events. |
| VC (Clamping Voltage) | ≤85.0 V at 4.7 A (10/1000 µs) - Measured peak voltage across device during rated surge; determines protected circuit's maximum stress level. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability per single 10/1000 µs waveform; enables protection against IEC 61000-4-5 Level 3 surges. |
| IPPM (Peak Pulse Current) | 4.7 A - Maximum non-repetitive surge current the device passes while clamping within spec; sets minimum line impedance requirement. |
| TJmax | 175 °C - Maximum allowable junction temperature; supports operation in under-hood automotive and high-ambient industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing per AEC specification. |
Pinout & Package
DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads solderable per J-STD-002 and JESD22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional transient conduction path | No functional distinction between leads; either terminal serves as input/output for AC-coupled or floating signal lines. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt surge energy before reaching downstream ASIC or MCU. Use Value: Maintains signal integrity by limiting transient voltage to ≤85 V while surviving repeated 12 V/24 V system-level surges per ISO 16750-2. |
Use Scenario: Safeguarding digital input channels of programmable logic controllers against field-wiring induced surges in factory automation. IC Role / Device Role / Timing Role: Front-end transient suppressor on 24 V DC input terminals, coordinated with upstream fusing and filtering. Use Value: Prevents false triggering or latch-up in optocoupler-isolated inputs by clamping fast-rising transients (<1 ns response) without affecting steady-state operation. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding RS-485/RS-232 transceivers in base station backhaul equipment from lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Secondary-level protector located after gas discharge tube (GDT) primary suppression, handling residual energy. Use Value: Achieves <100 V clamping at 4.7 A, ensuring transceiver survival under IEC 61000-4-5 2 kV/1 kA test conditions. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines, HVAC blowers, and power tools. IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals to absorb inductive kickback during MOSFET/FET switching. Use Value: Limits flyback voltage to ≤85 V, preventing gate oxide damage to driving FETs and reducing EMI radiation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ53A-E3/52 | DO-214AA package; 53 V VWM; 400 W PPPM; unidirectional only; higher IPPM (6.3 A); lower VC (87 V) | Requires polarity-aware layout; better suited for DC-biased rails where directionality is fixed. | Select when board space allows SMB footprint and unidirectional clamping suffices with tighter VC tolerance. |
| 1.5KE56A | DO-201AD package; 56 V VWM; 1500 W PPPM; unidirectional; higher VC (93.6 V); larger thermal mass | Designed for higher-energy surges; less suitable for compact automotive modules due to size and lack of AEC-Q101 rating. | Choose only for legacy industrial designs requiring >1 kW surge handling and where AEC-Q101 compliance is not mandated. |
Compared with BZW04-53BHE3/54, SMBJ53A-E3/52 offers superior surge current capacity in a surface-mount format but lacks bidirectionality and automotive qualification; 1.5KE56A provides higher power rating but sacrifices AEC-Q101 validation, DO-41 compatibility, and precision clamping voltage.

FAQ
What is the polarity configuration of BZW04-53BHE3/54?
BZW04-53BHE3/54 is a bidirectional TVS diode with symmetrical conduction characteristics in both forward and reverse directions. It has no cathode marking and functions identically regardless of terminal orientation, making it ideal for AC-coupled or floating signal lines where polarity cannot be guaranteed.
Is BZW04-53BHE3/54 qualified for automotive use?
Yes, BZW04-53BHE3/54 carries the HE3 suffix, confirming full AEC-Q101 qualification. This includes validation for temperature cycling, high-temperature reverse bias, and mechanical shock - meeting requirements for deployment in engine control units, body electronics, and ADAS sensor modules.
What is the clamping voltage of BZW04-53BHE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-53BHE3/54 is 85.0 V when subjected to a 10/1000 µs waveform at 4.7 A peak pulse current. This value is measured bidirectionally and defines the upper voltage limit imposed on protected circuitry during transient events.
Does BZW04-53BHE3/54 require heatsinking for standard operation?
No, BZW04-53BHE3/54 does not require external heatsinking under normal surge conditions. Its 1.5 W steady-state power dissipation (PD) and DO-41 package are thermally sufficient for intermittent transient suppression; heatsinking is only needed if subjected to frequent high-duty-cycle surges beyond datasheet derating curves.
How does the HE3 suffix differ from the E3 suffix in BZW04-53BHE3/54?
The HE3 suffix in BZW04-53BHE3/54 indicates AEC-Q101 qualification and JESD201 Class 2 whisker resistance, whereas E3 denotes commercial-grade RoHS compliance only. HE3 devices undergo additional automotive-specific stress testing and are approved for use in safety-critical vehicle subsystems.
