Product details
Overview
BZW04P64B-E3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 64.1 V stand-off voltage (VWM), 103 V clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the BZW04P64B-E3/54 datasheet, BZW04P64B-E3/54 pinout, BZW04P64B-E3/54 application, or BZW04P64B-E3/54 equivalent, key selection criteria include its bi-directional clamping behavior, AEC-Q101 qualification, DO-41 package compatibility, and verified 175 °C junction temperature rating for under-hood and high-reliability environments.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, delivering consistent clamping performance without polarity dependency. Its glass-passivated chip junction ensures stable breakdown characteristics and low incremental surge resistance across repetitive transients.
Designed for 10/1000 μs surge waveforms at 0.01% duty cycle, it sustains 400 W peak pulse power while maintaining tight VBR tolerance (71.3–82.5 V) and low temperature coefficient (0.105 %/°C), enabling predictable protection in wide-temperature industrial and automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - maximum continuous reverse operating voltage before clamping initiates; defines safe working margin for 48 V and 60 V nominal systems. |
| VC @ IPPM | 103 V - clamped voltage at 3.9 A peak pulse current; limits downstream IC stress during lightning or ESD events. |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform; supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge immunity. |
| VBR min/max | 71.3 V / 82.5 V - breakdown voltage range at 1 mA test current; ensures reliable turn-on with margin above VWM. |
| TJ max | +175 °C - maximum junction temperature; enables operation in engine control units and industrial motor drives. |
| ID @ VWM | 1.0 μA - maximum reverse leakage at stand-off voltage; minimizes standby power loss in battery-powered sensors. |
| Package | DO-204AL (DO-41) - industry-standard axial leaded package with UL 94 V-0 epoxy molding and matte tin-plated leads. |
Pinout & Package
DO-204AL (DO-41) package: axial-leaded, cylindrical glass-passivated body with matte tin-plated leads compliant to J-STD-002 and JESD22-B102. Bi-directional construction means no polarity marking; both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | No defined anode/cathode; conducts identically in either direction upon exceeding VBR threshold. |
| Lead 1 | Transient current entry point | Accepts surge energy from protected line; connects directly to I/O or power rail requiring clamping. |
| Lead 2 | Transient current return path | Completes low-inductance path to ground or reference plane; requires short PCB trace to minimize clamping overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - suitable for engine control, ADAS, and body electronics. |
| Glass passivated junction | Ensures stable VBR over lifetime and improved moisture resistance vs. epoxy-passivated alternatives - critical for outdoor and under-hood use. |
| 400 W 10/1000 μs rating | Meets IEC 61000-4-5 surge immunity requirements for industrial equipment and telecom infrastructure without external derating. |
| Low clamping ratio (VC/VBR ≈ 1.3) | Minimizes overvoltage exposure to protected ICs - e.g., 103 V clamp limits stress on 100 V-rated CAN transceivers or RS-485 drivers. |
| RoHS-compliant, whisker-tested (JESD201 Class 1A) | E3 suffix confirms matte tin plating meets strict solder joint reliability standards for high-volume automated assembly. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

IC Role / Device Role / Timing Role: Secondary-level protection aligned with primary gas discharge tube (GDT) in multi-stage architecture. Use Value: Fast response (<1 ns) and low VC ensure transceiver survival during combined fast-rising ESD + slow-rising surge events. |
Use Scenario: ESD suppression on DC output rails of USB-C PD adapters subject to IEC 61000-4-2 ±15 kV contact discharge. IC Role / Device Role / Timing Role: Final-stage shunt protector between +20 V output and ground after DC-DC regulation. Use Value: 1.0 μA leakage at 64.1 V avoids efficiency loss in high-efficiency GaN-based adapters while clamping to safe levels. |
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 | Same DO-214AA package; 64 V VWM, 104 V VC, but lower 600 W PPPM rating and non-AEC-Q101 commercial grade. | Lacks automotive qualification and has higher thermal resistance due to SMD footprint - unsuitable for under-hood mounting. | Select when board space is constrained and AEC-Q101 is not required; verify layout thermal relief for 600 W pulse dissipation. |
| 1.5KE68CA | Higher 68 V VWM, 112 V VC, 1500 W PPPM, DO-201AD package; larger size and higher clamping voltage than BZW04P64B-E3/54. | Better for high-energy surges but introduces higher let-through voltage - may exceed voltage tolerance of protected 3.3 V/5 V ICs. | Prefer for legacy industrial designs needing higher surge margin; avoid where low VC is critical for sensitive interface ICs. |
Compared with SMBJ64CA and 1.5KE68CA, BZW04P64B-E3/54 offers the optimal balance of AEC-Q101 compliance, compact DO-41 form factor, and low 103 V clamping - making it the preferred choice for space-constrained, high-reliability automotive and industrial edge nodes where precise voltage limiting is essential.

FAQ
What is the clamping voltage of BZW04P64B-E3/54 at its rated peak pulse current?
The BZW04P64B-E3/54 has a maximum clamping voltage (VC) of 103 V at 3.9 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 88316) and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 100 V-rated interface ICs.
Is BZW04P64B-E3/54 suitable for automotive applications?
Yes, BZW04P64B-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its 175 °C maximum junction temperature, glass-passivated junction, and validation across temperature cycling, high-temperature reverse bias, and surge endurance make it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and electrical stress is mandatory.
What does the "B" suffix in BZW04P64B-E3/54 indicate?
The "B" suffix in BZW04P64B-E3/54 denotes bi-directional functionality. Unlike uni-directional variants (e.g., BZW04P64-E3/54), this part provides symmetrical clamping in both polarities - eliminating the need for polarity-aware placement and simplifying design for AC-coupled or floating signal lines such as RS-485 buses or differential sensor outputs.
What package type is used for BZW04P64B-E3/54?
BZW04P64B-E3/54 uses the DO-204AL (commonly known as DO-41) axial-leaded package. It features a molded epoxy body meeting UL 94 V-0 flammability rating, matte tin-plated leads compliant with J-STD-002, and mechanical dimensions standardized per Vishay's package outline drawing - enabling drop-in compatibility with existing DO-41 footprints.
How does the temperature coefficient affect BZW04P64B-E3/54's performance?
The BZW04P64B-E3/54 has a maximum temperature coefficient of VBR of 0.105 %/°C. This means its breakdown voltage increases by up to 0.105% per degree Celsius rise in junction temperature - resulting in a ~1.1 V increase in VBR from −40 °C to +125 °C. Designers must account for this drift when setting safety margins in wide-temperature applications like automotive under-hood systems.
