Product details
Overview
BZW04-64-E3/54 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 a 64.1 V stand-off voltage (VWM), 71.3–78.8 V breakdown voltage (VBR) at 1 mA test current, 103 V maximum clamping voltage at 3.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFET gates, sensor interfaces, and industrial I/O circuits.
For engineers reviewing the BZW04-64-E3/54 datasheet, BZW04-64-E3/54 pinout, BZW04-64-E3/54 application, or BZW04-64-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, leakage current at operating bias, thermal derating above 25 °C, and compatibility with automated PCB assembly due to its DO-41 leaded package and matte tin-plated leads.
Technical Context
This device operates bidirectionally with symmetrical avalanche breakdown characteristics in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance under repetitive 10/1000 μs pulses at 0.01% duty cycle.
Designed for transient suppression per ANSI/IEEE C62.35, it delivers sub-nanosecond response time and clamps induced surges from inductive switching or ESD events before downstream components experience overstress. The 175 °C maximum junction temperature and -55 °C to +175 °C operating range support deployment in automotive under-hood and industrial control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - maximum continuous reverse working voltage before significant leakage; sets upper limit for normal circuit bias. |
| VBR min/max | 71.3 V / 78.8 V at 1 mA - guaranteed avalanche onset range; defines minimum overvoltage threshold for clamping activation. |
| VC @ IPPM | 103 V at 3.9 A - clamped voltage during 10/1000 μs surge; must remain below protected device's absolute max rating. |
| PPPM | 400 W - peak pulse power handling with standard 10/1000 μs waveform; determines survivability against defined surge events. |
| ID @ VWM | 1.0 μA - reverse leakage at stand-off voltage; critical for low-power sensor or battery-backed circuits. |
| TJ max | +175 °C - maximum junction temperature; enables use in high-ambient industrial or automotive locations. |
| Package | DO-41 (DO-204AL) - axial-leaded through-hole package with UL 94 V-0 epoxy molding; compatible with wave soldering (275 °C, 10 s). |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, cylindrical epoxy-molded case with matte tin-plated leads. No polarity marking - bidirectional operation confirmed by "B" suffix in family designation; BZW04-64-E3/54 is a bidirectional variant.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Surface-mount SMB package; 64 V VWM; 100 V VC @ 3.3 A; 600 W PPPM; unidirectional only. | Requires PCB redesign for SMT layout; unsuitable for bidirectional AC signals without dual-device configuration. | Select when space-constrained designs demand SMT and unidirectional protection suffices. |
| P6KE68CA | DO-15 package; 68 V VWM; 112 V VC @ 3.5 A; 600 W PPPM; bidirectional; higher clamping voltage. | Larger DO-15 footprint; 9 V higher VC reduces design margin for 5 V or 3.3 V ICs; same DO-xx leaded form factor. | Choose if legacy DO-15 socket compatibility is required and clamping margin permits 112 V peak. |
Compared with BZW04-64-E3/54, SMBJ64A offers higher pulse power but lacks bidirectionality and requires SMT rework, while P6KE68CA retains through-hole compatibility but sacrifices 9 V of clamping headroom - making BZW04-64-E3/54 optimal for new DO-41 designs prioritizing low VC and bidirectional robustness.

FAQ
What is the polarity configuration of BZW04-64-E3/54?
BZW04-64-E3/54 is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants (e.g., BZW04-64), it has no cathode marking and functions identically across either terminal - essential for protecting AC-coupled or floating signal paths without polarity concerns. This behavior is confirmed in the datasheet's "Bidirectional Types" table and "Polarity" note.
Does BZW04-64-E3/54 meet AEC-Q101 for automotive use?
No - BZW04-64-E3/54 carries the "E3" suffix, indicating RoHS-compliant commercial-grade qualification only. For AEC-Q101 qualification, the "HE3" variant (e.g., BZW04-64-HE3/54) must be selected, as explicitly stated in the "Ordering Information" and "Mechanical Data" sections. The E3 version lacks the extended reliability testing required for automotive under-hood deployment.
What is the maximum clamping voltage of BZW04-64-E3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-64-E3/54 is 103 V, measured at its rated peak pulse current (IPPM) of 3.9 A using the standardized 10/1000 μs waveform. This value is specified in the "Electrical Characteristics" table and defines the highest voltage that will appear across the protected circuit during a worst-case transient event - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings.
Can BZW04-64-E3/54 be used in high-temperature environments?
Yes - BZW04-64-E3/54 is rated for an operating junction temperature (TJ) up to +175 °C and storage from -55 °C to +175 °C. Its thermal performance is validated per Fig. 2 (derating curve) and Fig. 5 (power derating), allowing reliable operation in industrial control cabinets or near heat-generating components, provided PCB copper area and ambient airflow meet thermal dissipation requirements for its 1.5 W steady-state power rating.
How does the DO-41 package of BZW04-64-E3/54 support manufacturing?
The DO-41 (DO-204AL) package of BZW04-64-E3/54 features matte tin-plated leads compliant with J-STD-002 and JESD22-B102, enabling robust wetting during wave soldering at up to 275 °C for 10 seconds. Its axial-leaded form factor supports both manual assembly and automated through-hole insertion, and the UL 94 V-0 epoxy body ensures flame resistance - simplifying process validation and reducing rework in high-volume production of industrial and consumer electronics.
