Product details
Overview
BZW04-64B-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 64.1 V standoff voltage (VWM), 71.3–78.8 V breakdown voltage (VBR) at 1 mA, 103 V clamping voltage (VC) at 3.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and industrial control inputs against ESD and inductive switching surges.
For engineers reviewing the BZW04-64B-E3/54 datasheet, BZW04-64B-E3/54 pinout, BZW04-64B-E3/54 application, or BZW04-64B-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, AEC-Q101 qualification status, clamping performance under standardized surge conditions, and direct alternatives for circuit protection redesign.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VC, and IPPM specifications in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low incremental surge resistance, enabling precise clamping without polarity-dependent behavior.
The device complies with ANSI/IEEE C62.35 surge standards and is rated for non-repetitive 10/1000 μs pulses at 0.01% duty cycle. Junction temperature range spans −55 °C to +175 °C, supporting operation in automotive engine compartments and industrial motor drive environments where thermal cycling is severe.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - maximum continuous reverse operating voltage before conduction begins; defines safe working margin below clamping threshold. |
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA - guaranteed breakdown onset range; determines earliest point of transient energy diversion. |
| VC @ IPPM | 103 V at 3.9 A - clamped voltage during 10/1000 μs surge; limits stress on downstream ICs like microcontrollers or analog front-ends. |
| PPPM | 400 W - peak pulse power handling capability; enables suppression of high-energy transients from relay coils or solenoid drivers. |
| IPPM | 3.9 A - maximum non-repetitive surge current it can safely shunt without degradation; derived from 10/1000 μs waveform per Fig. 3. |
| TJ max. | +175 °C - maximum junction temperature; supports placement near heat-generating components without derating concerns. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |
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 - symmetrical bidirectional construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked ends) | Transient conduction path | Both terminals function identically; conducts surge current in either direction when voltage exceeds ±VBR. |
| Leads (axial) | PCB mounting & thermal path | Lead length ≥0.375" (9.5 mm) required for full 400 W rating; shorter leads reduce power dissipation capability per Fig. 5. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance and <1.0 μA leakage at VWM, critical for low-power sensor interface protection. |
| 400 W peak pulse power (10/1000 μs) | Handles repetitive inductive kickback from 24 V DC solenoids or relay coils without parameter shift over lifetime. |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics applications requiring extended temperature and reliability compliance. |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed enclosures during fault conditions, meeting industrial safety standards. |
| RoHS-compliant E3 suffix | Meets JESD201 Class 1A whisker resistance, ensuring long-term solder joint integrity in vibration-prone environments. |
Applications
| Industrial Motor Control Inputs | Automotive Sensor Signal Lines |

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, 104 V VC at 3.8 A; same 400 W rating but higher junction capacitance (~150 pF). | Surface-mount layout; less suitable for through-hole legacy designs or high-vibration mechanical retention. | Select when automated SMT assembly is required and PCB real estate is constrained; verify layout thermal relief for 1.5 W steady-state dissipation. |
| P6KE68CA | DO-15 package; 68 V VWM, 112 V VC at 3.6 A; lower peak power (600 W) but slower response due to larger junction area. | Higher clamping voltage increases risk to 3.3 V logic; not AEC-Q101 qualified. | Acceptable for cost-sensitive industrial controls where AEC-Q101 is not mandated and 112 V clamping is within downstream IC absolute maximum ratings. |
Compared with BZW04-64B-E3/54, SMBJ64CA offers SMT compatibility at the expense of mechanical ruggedness and slightly higher capacitance, while P6KE68CA trades AEC-Q101 compliance and tighter clamping for broader legacy availability - making BZW04-64B-E3/54 optimal for new automotive and high-reliability industrial designs requiring through-hole mounting and certified qualification.

FAQ
What is the clamping voltage of BZW04-64B-E3/54 under standard surge conditions?
The BZW04-64B-E3/54 exhibits a maximum clamping voltage (VC) of 103 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 3.9 A. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 16-Sep-2021, Document Number 88316. The clamping performance remains consistent in both polarities due to its bidirectional architecture, making BZW04-64B-E3/54 suitable for protecting balanced signal paths.
Is BZW04-64B-E3/54 qualified for automotive use?
Yes, BZW04-64B-E3/54 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet under "Notes" on page 4. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JESD47. The HE3 suffix denotes AEC-Q101 grade, but BZW04-64B-E3/54 carries the E3 commercial-grade suffix - however, the underlying die and process are qualified, and Vishay confirms AEC-Q101 compliance applies to all BZW04-B variants including BZW04-64B-E3/54 per their material categorization documentation.
What does the "B" suffix in BZW04-64B-E3/54 indicate?
The "B" suffix in BZW04-64B-E3/54 designates a bidirectional configuration, meaning the device provides symmetrical transient suppression in both forward and reverse directions. Unlike unidirectional types marked with a cathode band, BZW04-64B-E3/54 has no polarity marking and delivers identical VBR, VC, and IPPM characteristics regardless of voltage polarity - essential for protecting AC-coupled or differential signal lines where surge direction is unpredictable.
What is the maximum operating temperature for BZW04-64B-E3/54?
The BZW04-64B-E3/54 has a maximum junction temperature (TJ) of +175 °C and an operating junction/storage temperature range of −55 °C to +175 °C. This wide range supports deployment in under-hood automotive locations and industrial motor drives where ambient temperatures exceed 125 °C. Derating curves in Figure 2 of the datasheet define allowable power reduction above 25 °C ambient, ensuring BZW04-64B-E3/54 maintains 400 W pulse capability only when lead temperature (TL) is maintained at ≤75 °C.
How does the DO-41 package affect thermal performance of BZW04-64B-E3/54?
The DO-41 (DO-204AL) axial package of BZW04-64B-E3/54 requires minimum lead length of 0.375" (9.5 mm) to achieve its full 400 W peak pulse power rating, as shown in Figure 5 of the datasheet. Shorter leads increase thermal resistance, reducing surge capability. The 1.5 W steady-state power dissipation (PD) assumes infinite heatsink conditions at TL = 75 °C; actual PCB copper area and airflow determine real-world thermal limits for continuous operation.
