Overview
BZW04-15-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of signal and power lines. It features a 15.3 V standoff voltage (VWM), 17.1–18.9 V breakdown range (VBR at 1 mA), 25.2 V clamping voltage (VC) at 16.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line conditioning.
For engineers reviewing the BZW04-15-E3/73 datasheet, BZW04-15-E3/73 pinout, BZW04-15-E3/73 application, or BZW04-15-E3/73 equivalent, this device delivers AEC-Q101-qualified transient suppression for bidirectional AC-coupled or floating signal paths where low leakage (<1 μA at VWM), fast response (<1 ns), and stable temperature coefficient (0.088 %/°C) are critical to system reliability.
Technical Context
This TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling protection of ungrounded differential pairs or AC signal lines without polarity constraints. Its glass-passivated junction ensures stable leakage and low incremental surge resistance across temperature.
The device complies with ANSI/IEEE C62.35 surge standards and is rated for non-repetitive 10/1000 μs transients up to 400 W, derated linearly above 25 °C ambient per Fig. 2. Junction temperature is rated from –55 °C to +175 °C, supporting under-hood automotive and high-temperature industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.3 V - Maximum continuous reverse working voltage before significant conduction begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 17.1 V / 18.9 V at 1 mA - Verified breakdown threshold range; ensures consistent clamping onset across production lots. |
| VC @ IPPM | 25.2 V at 16.0 A - Clamped voltage during 10/1000 μs surge; limits downstream IC stress to safe levels. |
| PPPM | 400 W - Peak pulse power handling capability; supports IEC 61000-4-5 Level 4 (4 kV) surge compliance when properly laid out. |
| ID @ VWM | <1.0 μA - Ultra-low reverse leakage at rated standoff; preserves signal integrity in high-impedance sensor or data lines. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in engine control units and industrial motor drives without thermal derating. |
| Temp. Coeff. | 0.088 %/°C - Predictable VBR drift with temperature; simplifies design margining across –40 °C to +125 °C ambient. |

IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and ground, absorbing transients before they reach ADC front-end or MCU GPIO. Use Value: Maintains signal fidelity under 100 V/100 ms load dump events while drawing <1 μA at 15 V nominal supply - no impact on sensor offset or gain calibration. |
Use Scenario: Shielding 4–20 mA current loop inputs in PLC analog modules from ESD and inductive switching noise in factory automation cabinets. IC Role / Device Role / Timing Role: Fast-acting shunt protector across input terminals, triggered within nanoseconds to clamp spikes exceeding ±25 V. Use Value: Limits transient voltage to ≤25.2 V during 16 A surges, preventing damage to precision op-amps and isolators without affecting loop accuracy or zero-point stability. |
| Telecom Line Interface | Consumer USB Port ESD Protection |
Use Scenario: Safeguarding RS-485 transceivers in outdoor security camera links subjected to induced lightning surges on twisted-pair cabling. IC Role / Device Role / Timing Role: Common-mode TVS across differential pair (A/B) and ground, suppressing asymmetric surges while preserving signal integrity. Use Value: Symmetric 17.1–18.9 V breakdown ensures balanced clamping on both lines, eliminating common-mode-to-differential conversion that could corrupt data. |
Use Scenario: Secondary-level protection on USB 2.0 D+/D– lines behind primary polymer-based TVS, targeting contact ESD per IEC 61000-4-2 ±8 kV. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF typical) bidirectional clamp limiting voltage excursion to ≤25.2 V during 30 A ESD events. Use Value: Adds <1 μA leakage and negligible capacitance to high-speed data path - no signal rise-time degradation or eye-diagram closure. |
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 | DO-214AA package (SMB), 15 V VWM, 24.4 V VC @ 16.3 A, 600 W PPPM | Higher power rating but larger footprint; requires PCB rework for DO-41 replacement | Select SMBJ15CA only when higher surge margin (>400 W) is required and board space allows SMB footprint. |
| P6KE15CA | DO-15 package, 15 V VWM, 24.4 V VC @ 16.3 A, 600 W PPPM, slower response due to higher junction capacitance | Legacy through-hole alternative with lower surge endurance consistency and higher leakage at elevated temperature | Prefer BZW04-15-E3/73 over P6KE15CA for AEC-Q101-compliant designs and tighter leakage budgets. |
Compared with SMBJ15CA and P6KE15CA, BZW04-15-E3/73 offers AEC-Q101 qualification, lower leakage (<1 μA vs. ≥5 μA), and DO-41 compatibility for legacy through-hole layouts - making it optimal for cost-sensitive automotive and industrial replacements where footprint and reliability are prioritized over peak power headroom.

FAQ
What is the polarity configuration of BZW04-15-E3/73?
BZW04-15-E3/73 is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants (e.g., BZW04-15), it has no cathode band marking and functions identically regardless of voltage polarity - ideal for AC-coupled or floating signal lines where polarity is undefined or alternating.
Is BZW04-15-E3/73 AEC-Q101 qualified?
Yes, BZW04-15-E3/73 carries the HE3 suffix variant for AEC-Q101 qualification; however, the E3/73 suffix denotes RoHS-compliant commercial grade. For automotive use, specify BZW04-15HE3/73 - which shares identical electrical specs but includes full AEC-Q101 stress test documentation and lot traceability required for Tier 1 automotive programs.
What is the maximum clamping voltage of BZW04-15-E3/73 under surge conditions?
The maximum clamping voltage (VC) of BZW04-15-E3/73 is 25.2 V at 16.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across temperature and production lots, ensuring downstream circuitry remains below destructive thresholds during standardized surge events such as IEC 61000-4-5.
Can BZW04-15-E3/73 replace P6KE15CA in existing designs?
BZW04-15-E3/73 can replace P6KE15CA electrically in most cases - same VWM (15 V), comparable VC (25.2 V vs. 24.4 V), and DO-41 footprint compatibility. However, P6KE15CA uses DO-15 packaging with longer leads and higher junction capacitance; verify layout clearance and signal integrity if migrating from P6KE15CA to BZW04-15-E3/73 in high-frequency applications.
What is the reverse leakage current of BZW04-15-E3/73 at its rated standoff voltage?
At VWM = 15.3 V and TA = 25 °C, the maximum reverse leakage current (ID) of BZW04-15-E3/73 is 1.0 μA. This ultra-low leakage is maintained up to +125 °C ambient (≤5 μA), making it suitable for high-impedance sensor front-ends and battery-powered systems where standby current must be minimized.
