Product details
Overview
BZW04P64BHE3/73 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 maximum clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 400 W peak pulse power capability with a 10/1000 µs waveform - suitable for protecting MOSFETs, sensor interfaces, and industrial I/O circuits against ESD and inductive switching transients.
For engineers reviewing the BZW04P64BHE3/73 datasheet, BZW04P64BHE3/73 pinout, BZW04P64BHE3/73 application, or BZW04P64BHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package, bi-directional symmetry, low leakage (<1 µA at VWM), and temperature coefficient of breakdown voltage (0.105 %/°C).
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling fast response to transients (<1 ns typical) while maintaining tight VBR tolerance (71.3–78.8 V at 1 mA test current).
The device is rated for 400 W peak pulse power under standard 10/1000 µs waveform conditions, derated linearly above 25 °C ambient per Fig. 2, and supports continuous power dissipation of 1.5 W on an infinite heatsink at lead temperature (TL) = 75 °C. Junction temperature range spans –55 °C to +175 °C, validated per AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V - Maximum continuous working voltage before clamping begins; defines safe operating margin below system rail. |
| VC @ IPPM | 103 V - Clamped voltage at 3.9 A peak pulse current; determines protected circuit's maximum transient exposure. |
| IPPM | 3.9 A - Peak pulse current capability with 10/1000 µs waveform; quantifies surge energy handling (400 W). |
| VBR min/max | 71.3 V / 78.8 V - Breakdown voltage range at 1 mA; ensures consistent triggering across production lots. |
| TJ max | +175 °C - Maximum junction temperature; enables reliable operation in under-hood automotive and industrial environments. |
| Package | DO-204AL (DO-41) - Standard axial-leaded through-hole package compatible with legacy PCB layouts and wave soldering. |
| Qualification | AEC-Q101 qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD. |
Pinout & Package
DO-204AL (DO-41) package: axial-leaded, molded epoxy body with matte tin-plated leads compliant to J-STD-002 and JESD22-B102. Bi-directional construction means no polarity marking; both terminals are electrically symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Bi-directional clamping node - conducts surge current equally in either direction when VWM is exceeded. |
| Lead 1 | Terminal A | Standard axial lead; solderable per JESD22-B106 (275 °C, 10 s max); no functional distinction from Lead 2. |
| Lead 2 | Terminal B | Identical to Lead 1; interchangeable due to bi-directional symmetry - no cathode band or polarity indicator. |
Key Features
| Feature | Design Value |

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 VWM (64 V), higher IPPM (8.3 A), SMC package (surface-mount), lower VC (104 V), same 400 W rating. | Preferred where board space is constrained and reflow assembly is used; not drop-in compatible with through-hole layouts. | Select SMBJ64CA for automated SMT production and tighter clamping tolerance; retain BZW04P64BHE3/73 for legacy through-hole designs requiring AEC-Q101 traceability. |
| P6KE68CA | Higher VWM | Used in general-purpose industrial power supplies where ±68 V standoff suffices and AEC-Q101 is not required. | Choose P6KE68CA for cost-sensitive commercial power systems; BZW04P64BHE3/73 remains optimal for automotive-qualified bi-directional protection at 64.1 V. |
Compared with SMBJ64CA and P6KE68CA, BZW04P64BHE3/73 uniquely combines AEC-Q101 qualification, DO-41 through-hole compatibility, and precise 64.1 V stand-off in a bi-directional configuration - making it the preferred choice for automotive sensor modules and industrial control hardware requiring proven reliability and mechanical serviceability.

FAQ
What is the clamping voltage of BZW04P64BHE3/73 at its rated peak pulse current?
The BZW04P64BHE3/73 has a maximum clamping voltage (VC) of 103 V at its specified peak pulse current (IPPM) of 3.9 A with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The BZW04P64BHE3/73 maintains this clamping performance across its full operating temperature range (–55 °C to +175 °C).
Is BZW04P64BHE3/73 suitable for automotive applications?
Yes, BZW04P64BHE3/73 is AEC-Q101 qualified and specifically tested for automotive-grade reliability, including temperature cycling, high-temperature reverse bias, and ESD. Its DO-204AL package, 175 °C max junction temperature, and bi-directional symmetry make it appropriate for engine control units, body electronics, and ADAS sensor protection. The "HE3" suffix confirms AEC-Q101 qualification per Vishay's ordering nomenclature.
How does the bi-directional design of BZW04P64BHE3/73 affect its circuit implementation?
The bi-directional design of BZW04P64BHE3/73 eliminates polarity concerns - both terminals are functionally identical, and no cathode band marking is present. This allows placement across AC-coupled lines, differential buses (e.g., RS-485), or unidirectional rails where reverse transients may occur. Unlike uni-directional TVS diodes, the BZW04P64BHE3/73 provides symmetrical clamping in both directions without requiring external series components or orientation checks during assembly.
What is the maximum steady-state power dissipation of BZW04P64BHE3/73?
The BZW04P64BHE3/73 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C. This rating applies to continuous DC or low-frequency operation and is derated linearly above 25 °C ambient per the power derating curve in Figure 5 of the datasheet. For pulsed operation, the 400 W peak pulse rating governs short-duration surge handling.
Does BZW04P64BHE3/73 have RoHS and REACH compliance documentation?
Yes, BZW04P64BHE3/73 is RoHS-compliant per Directive 2011/65/EU and REACH-conformant, with its "HE3" suffix indicating AEC-Q101 qualification and RoHS compliance. Vishay certifies all HE3-suffix parts meet UL 94 V-0 flammability requirements and JESD201 Class 2 whisker resistance. Full compliance documentation, including material declarations and test reports, is available via Vishay's official product page for BZW04P64BHE3/73.
