Product details
Overview
BZW04P15HE3/73 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 15.3 V stand-off voltage (VWM), 25.2 V clamping voltage (VC) at 16.0 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 cards.
For engineers reviewing the BZW04P15HE3/73 datasheet, BZW04P15HE3/73 pinout, BZW04P15HE3/73 application, or BZW04P15HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package compatibility, bi-directional surge handling, and verified clamping performance under repetitive transients induced by inductive switching.
Technical Context
This bi-directional TVS diode uses a glass passivated chip junction to achieve fast response time (<1 ns), low incremental surge resistance, and stable breakdown characteristics across temperature. Its symmetrical structure enables identical electrical behavior in both polarities, eliminating polarity marking on the device body.
Designed for transient suppression per ANSI/IEEE C62.35, it delivers repeatable 400 W pulse power handling at TA = 25 °C, derated linearly above 25 °C per Fig. 2, with maximum junction temperature of 175 °C and storage range from –55 °C to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 15.3 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VC (Clamping Voltage) | 25.2 V at IPPM = 16.0 A - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge; ensures downstream ICs remain within absolute maximum ratings. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; validated for ≤0.01% duty cycle repetition. |
| VBR (Breakdown Voltage) | 17.1–19.8 V at IT = 1.0 mA - Measured voltage where device enters avalanche conduction; tight min/max spread ensures predictable turn-on behavior. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | 175 °C - Enables reliable operation in under-hood automotive and industrial environments without thermal derating penalties. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |
Pinout & Package
Package: DO-204AL (DO-41), axial lead, molded epoxy case meeting UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. Bi-directional construction means no cathode marking - terminals are non-polarized.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Either terminal serves as input/output for bidirectional surge current; no polarity dependency simplifies PCB layout and eliminates orientation errors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Same DO-214AA package; 15 V VWM, 24.4 V VC at 16.3 A; lower PPPM (600 W), higher junction capacitance (~150 pF). | Better suited for higher-energy surges but less optimal for high-speed data lines due to capacitance. | Select SMBJ15CA when board space allows SMC/SMB footprint and higher pulse energy margin is required. |
| P6KE15CA | DO-15 package; 15 V VWM, 24.4 V VC at 16.3 A; 600 W PPPM; slower response (>5 ns); not AEC-Q101 qualified. | Acceptable for cost-sensitive industrial controls but unsuitable for automotive or high-reliability deployments. | Choose P6KE15CA only for non-automotive, non-safety-critical applications where qualification and speed are secondary. |
Compared with BZW04P15HE3/73, SMBJ15CA offers higher surge capacity in a surface-mount format but sacrifices AEC-Q101 compliance and adds layout complexity, while P6KE15CA provides legacy through-hole compatibility at the expense of automotive qualification and response speed - making BZW04P15HE3/73 the optimal choice for AEC-Q101–mandated, axial-leaded, bi-directional protection.
