Product details
Overview
BZW04P64BHE3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 64.1 V stand-off voltage (VWM), 71.3–82.5 V breakdown range (VBR at 1 mA), 103 V clamping voltage (VC) at 3.9 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification - making it suitable for automotive body electronics and industrial control I/O protection.
For engineers reviewing the BZW04P64BHE3/54 datasheet, BZW04P64BHE3/54 pinout, BZW04P64BHE3/54 application, or BZW04P64BHE3/54 equivalent, key selection criteria include its DO-41 package compatibility, bi-directional surge handling up to ±3.9 A, low leakage (<1 µA at VWM), and validated performance under repetitive transients per IEC 61000-4-5.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling single-device protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5% typical) and low temperature coefficient (0.105 %/°C).
The device uses a 10/1000 µs double-exponential surge waveform standard, delivering 400 W peak pulse power while maintaining clamping within 103 V at rated IPPM. Thermal derating follows JEDEC JESD22-A104, with full power rated at TA = 25 °C and linear reduction to zero at TJ = 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - Maximum continuous working voltage before conduction; defines safe operating ceiling for protected circuit. |
| VBR (min/max) | 71.3 V / 82.5 V at 1 mA - Breakdown onset range; ensures reliable triggering above normal operating voltage. |
| VC @ IPPM | 103 V at 3.9 A - Clamped voltage during 400 W transient; limits stress on downstream ICs like microcontrollers or CAN transceivers. |
| PPPM | 400 W - Peak pulse power rating (10/1000 µs); supports IEC 61000-4-5 Level 4 surge immunity testing. |
| IPPM | 3.9 A - Peak pulse current corresponding to VC; determines minimum trace width and PCB layout margin. |
| TJ max. | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |

Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protecting 12 V supply inputs and switch-sense lines in BCMs exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between input rail and chassis ground, responding within <1 ns to transients. Use Value: Limits voltage to ≤103 V during 3.9 A surges, preventing damage to MCU GPIOs and level translators without adding series impedance. |
Use Scenario: Safeguarding 24 V digital input channels on programmable logic controllers against field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Parallel-connected transient absorber across optocoupler input terminals, conducting only during overvoltage events. Use Value: Maintains <1 µA leakage at 24 V nominal, ensuring clean logic thresholds while clamping fast-rising transients to safe levels. |
| Automotive HVAC Sensor Interface | RS-485 Communication Line Protection |
Use Scenario: Shielding NTC thermistor and pressure sensor analog front-ends in HVAC control units from ESD and cable discharge events. IC Role / Device Role / Timing Role: Bi-directional shunt protector across sensor signal and return lines, suppressing ±8 kV contact ESD per IEC 61000-4-2. Use Value: Symmetric clamping prevents signal inversion or offset shift during transients, preserving measurement accuracy in sub-10 mV ranges. |
Use Scenario: Protecting half-duplex RS-485 transceivers (e.g., SN65HVD230) in factory automation networks from lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Differential-mode TVS placed between A/B bus lines and local ground, absorbing common-mode energy via coupled path. Use Value: 103 V clamping ensures transceiver survival during 4 kV surge tests while maintaining signal integrity up to 10 Mbps. |
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 (SMB) package; 64 V VWM, 104 V VC at 3.8 A; same 400 W rating but higher thermal resistance (RθJA ≈ 110 °C/W vs. DO-41's ~150 °C/W). | Surface-mount alternative for space-constrained PCBs; requires re-layout but offers better high-frequency surge response due to lower parasitic inductance. | Select SMBJ64CA when board area is limited and SMT assembly is preferred; verify thermal relief pad design for 1.5 W steady-state dissipation. |
| 1.5KE68CA | DO-201AD package; 68 V VWM, 112 V VC at 3.6 A; 1500 W peak rating but larger footprint and slower response due to higher junction capacitance (~100 pF vs. ~50 pF). | Higher-power legacy alternative for less sensitive circuits where clamping voltage margin allows >112 V excursion. | Choose 1.5KE68CA only if system-level testing confirms 112 V clamping is acceptable and board real estate permits larger axial package. |
Compared with SMBJ64CA and 1.5KE68CA, BZW04P64BHE3/54 provides optimal balance of AEC-Q101 compliance, DO-41 through-hole compatibility, low clamping voltage (103 V), and industry-standard 400 W surge rating - making it the preferred choice for cost-sensitive, high-reliability automotive and industrial replacements.

FAQ
What is the maximum clamping voltage of BZW04P64BHE3/54 under surge conditions?
The BZW04P64BHE3/54 has a maximum clamping voltage (VC) of 103 V at 3.9 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured per IEC 61000-4-5 and ensures downstream components see no more than 103 V during a 400 W transient event. The BZW04P64BHE3/54 maintains this clamping performance across its qualified temperature range of –55 °C to +175 °C.
Is BZW04P64BHE3/54 suitable for automotive applications?
Yes, BZW04P64BHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, glass-passivated junction stability, and validation across temperature cycling, high-temperature reverse bias, and mechanical shock meet automotive reliability requirements. The BZW04P64BHE3/54 is commonly deployed in body control modules, HVAC systems, and lighting control units.
How does the bi-directional nature of BZW04P64BHE3/54 affect its placement in a circuit?
The bi-directional design of BZW04P64BHE3/54 means it conducts identically in both polarities - eliminating cathode/anode orientation concerns. It can be placed directly across any two nodes requiring symmetrical overvoltage protection, such as differential signal pairs (RS-485 A/B), AC-coupled sensors, or ungrounded power domains. No polarity marking exists on the DO-41 package, simplifying assembly and reducing misorientation risk. The BZW04P64BHE3/54 functions identically regardless of lead direction.
What is the leakage current specification for BZW04P64BHE3/54 at its stand-off voltage?
At its 64.1 V stand-off voltage (VWM), the BZW04P64BHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 µA at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes quiescent power draw in battery-operated systems. The BZW04P64BHE3/54 maintains leakage below 5 µA even at elevated temperatures up to 125 °C, per datasheet characterization.
Can BZW04P64BHE3/54 replace older uni-directional TVS diodes in existing designs?
Yes, BZW04P64BHE3/54 can replace uni-directional equivalents (e.g., BZW04P64HE3/54) in most cases, provided the circuit does not rely on forward conduction behavior. Its bi-directional symmetry ensures protection during both positive and negative transients without requiring polarity-aware layout. However, verify that the protected node is not referenced to a fixed rail where uni-directional blocking is intentional. The BZW04P64BHE3/54 retains identical VWM, VBR, and PPPM ratings as its uni-directional counterpart.
