Product details
Overview
BZW04-64HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 64.1 V standoff voltage (VWM), 71.3–78.8 V breakdown voltage (VBR), 103 V clamping voltage at 3.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the BZW04-64HE3/54 datasheet, BZW04-64HE3/54 pinout, BZW04-64HE3/54 application, or BZW04-64HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, bidirectional polarity, 175 °C max junction temperature, low 0.105 %/°C VBR temperature coefficient, and RoHS-compliant HE3 suffix indicating whisker-tested leads.
Technical Context
This device operates as a voltage-clamped surge protector: during transients exceeding VWM, it avalanches to limit voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown behavior and fast response (<1 ns), while the DO-41 package supports manual or automated through-hole assembly with JESD22-B106 solder compatibility.
Rated for 400 W peak pulse power (10/1000 μs), it delivers 3.9 A maximum peak pulse current (IPPM) with 103 V clamping voltage (VC). The 0.67 μA max reverse leakage at VWM minimizes standby power loss, and its -55 °C to +175 °C operating range supports under-hood automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - maximum continuous reverse working voltage before clamping initiates |
| VBR min/max | 71.3 V / 78.8 V at 1 mA test current - defines reliable avalanche onset window |
| VC @ IPPM | 103 V at 3.9 A - limits transient voltage seen by downstream ICs or MOSFETs |
| PPPM | 400 W - surge energy handling capacity per 10/1000 μs waveform, duty cycle ≤ 0.01 % |
| IPPM | 3.9 A - peak surge current the device safely shunts without degradation |
| TJ max | +175 °C - enables operation in high-temperature engine control units and motor drives |
| Leakage @ VWM | 0.67 μA - negligible standby current draw in always-on sensor circuits |
| Temp. coeff. VBR | 0.105 %/°C - predictable VBR drift over temperature for stable protection threshold |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking for bidirectional configuration - both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |

Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector interface to divert surge energy before reaching signal conditioning ICs. Use Value: Maintains signal integrity under ISO 16750-2 load dump (12 V system: +120 V/100 ms) and prevents latch-up in 3.3 V/5 V microcontrollers. |
Use Scenario: Safeguarding digital input cards in programmable logic controllers against field-wiring induced surges from solenoid valves and contactors. IC Role / Device Role / Timing Role: Front-end TVS on each 24 V DC input channel, absorbing repetitive 400 W transients without derating. Use Value: Enables >100,000 surge cycles per channel with no parameter shift, reducing field failure rates in factory automation equipment. |
| Telecom Line Interface | Consumer Appliance Motor Control |
|
Use Scenario: Shielding RS-485 transceivers and Ethernet PHYs in base station remote units from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary protection device in multi-stage architecture - clamps fast-rising transients before secondary GDT or polymer suppressors. Use Value: Achieves <1 ns response time and 103 V clamping to keep differential signal swing within ±7 V common-mode tolerance of ISO/IEC 8073 compliant transceivers. |
Use Scenario: Securing gate drivers and MCU GPIOs in washing machine motor inverters exposed to brush-commutator noise and relay bounce. IC Role / Device Role / Timing Role: Localized TVS on microcontroller reset line and half-bridge enable signals to prevent false triggering. Use Value: Eliminates firmware lockups caused by 1 kV EFT bursts (IEC 61000-4-4) due to sub-100 ps response and low dynamic impedance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | DO-214AA package, 64 V VWM, 100 V VC @ 3.6 A, 600 W PPPM | Surface-mount only; higher power but larger footprint than DO-41 | Select SMBJ64CA when board space permits SMT and higher surge margin is needed. |
| P6KE68CA | DO-15 package, 68 V VWM, 112 V VC @ 3.6 A, 600 W PPPM, no AEC-Q101 qualification | Higher clamping voltage and non-automotive grade; lower reliability in harsh environments | Choose P6KE68CA for cost-sensitive commercial applications where AEC-Q101 is not mandated. |
Compared with BZW04-64HE3/54, SMBJ64CA offers higher surge capability in SMT format but lacks AEC-Q101 validation, while P6KE68CA trades automotive qualification and tighter clamping for legacy DO-15 compatibility and lower unit cost - making BZW04-64HE3/54 optimal for new AEC-Q101-compliant designs requiring proven through-hole robustness.

FAQ
What is the polarity configuration of BZW04-64HE3/54?
BZW04-64HE3/54 is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. There is no cathode marking on the DO-41 package, and either lead may be used as anode or cathode - this configuration protects AC-coupled or differential signal lines such as RS-485 or CAN without polarity concerns. The B suffix in the family name confirms bidirectional functionality, and BZW04-64HE3/54 inherits this property.
Is BZW04-64HE3/54 qualified for automotive use?
Yes, BZW04-64HE3/54 is AEC-Q101 qualified, as confirmed by the HE3 suffix and documentation in Vishay's 88316 datasheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge endurance - validating its suitability for under-hood and chassis-mounted automotive modules. The HE3 designation also indicates compliance with JESD201 Class 2 whisker resistance, a requirement for high-reliability automotive harnesses.
What is the clamping voltage of BZW04-64HE3/54 at rated surge current?
The clamping voltage (VC) of BZW04-64HE3/54 is 103 V at 3.9 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the maximum voltage imposed on protected circuitry during a standardized surge event. It ensures downstream 5 V or 3.3 V logic interfaces remain within safe operating limits when BZW04-64HE3/54 is correctly placed at the entry point of the protected line.
How does the HE3 suffix differ from the E3 suffix in BZW04-64HE3/54?
The HE3 suffix in BZW04-64HE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance - essential for automotive applications. In contrast, the E3 suffix (e.g., BZW04-64-E3/54) indicates RoHS compliance and JESD201 Class 1A whisker testing but no AEC-Q101 validation. Both share identical electrical specs and DO-41 packaging, but only HE3 guarantees automotive-grade reliability and process control throughout manufacturing.
Can BZW04-64HE3/54 replace older P6KE64CA devices in existing designs?
BZW04-64HE3/54 can serve as a functional upgrade to P6KE64CA in through-hole layouts, offering tighter VBR tolerance (71.3–78.8 V vs. 68.4–75.6 V), lower clamping (103 V vs. 107 V), and AEC-Q101 qualification - but direct replacement requires verification of mechanical fit (DO-41 vs. DO-15 lead spacing) and thermal derating curves. The BZW04-64HE3/54's 0.105 %/°C temperature coefficient also improves threshold stability over temperature versus P6KE64CA's 0.095 %/°C.
