Product details
Overview
BZW04-15-E3/54 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 stand-off voltage (VWM), 17.1–18.9 V breakdown voltage (VBR) at 1 mA, 25.2 V clamping voltage (VC) at 16 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04-15-E3/54 datasheet, BZW04-15-E3/54 pinout, BZW04-15-E3/54 application, or BZW04-15-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, AEC-Q101 qualification status, clamping performance under surge conditions, and direct alternatives for ESD/lightning transient suppression in 12 V/24 V systems.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with no polarity marking on the DO-41 case. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing inductive switching transients and ESD events per IEC 61000-4-2 Level 4.
Rated for -55 °C to +175 °C junction temperature, it supports high-reliability automotive and industrial environments. The 1.5 W steady-state power dissipation and 400 W 10/1000 μs pulse capability are derated linearly above 25 °C ambient per Fig. 2, maintaining clamping integrity up to TJ = 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.3 V - maximum continuous reverse working voltage before significant leakage; defines safe operating margin below breakdown. |
| VBR min/max | 17.1 V / 18.9 V at 1 mA - tight breakdown tolerance ensures predictable turn-on during transients without false triggering. |
| VC @ IPPM | 25.2 V at 16 A - clamping voltage limits downstream IC stress during 400 W surge; <10 V overshoot above VWM. |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform; validated for repetitive 0.01 % duty cycle. |
| ID @ VWM | 1.0 μA - ultra-low reverse leakage preserves signal integrity and battery life in always-on circuits. |
| TJ max | +175 °C - extended thermal range enables under-hood automotive placement and high-ambient industrial use. |

| Consumer Power Adapter Output | Telecom Line Interface |
Use Scenario: Secondary-side overvoltage protection in AC/DC adapters for USB-C PD and laptop chargers exposed to mains-borne surges. IC Role / Device Role / Timing Role: Standoff-clamp device placed between +VOUT and GND, activated only during abnormal output overvoltage events. Use Value: Complements primary-side OVP by providing secondary-side fail-safe clamping, preventing damage to connected devices during regulator fault conditions. |
Use Scenario: Surge protection on POTS (Plain Old Telephone Service) line interface cards in VoIP gateways and PBX systems. IC Role / Device Role / Timing Role: Bidirectional TVS bridging tip/ring lines to protect SLIC (Subscriber Line Interface Circuit) and codec components from lightning-induced common-mode transients. Use Value: Maintains >60 dB common-mode rejection while clamping 1 kV/0.5 J transients to <30 V, preserving voice signal fidelity and meeting GR-1089-CORE requirements. |
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 VWM (15 V), but SMC package (higher thermal mass); 600 W PPPM vs. 400 W; 20 % higher VC (30 V). | Better suited for higher-energy surges; requires larger PCB footprint and different layout due to SMC-2 footprint. | Select SMBJ15CA when system-level testing shows 400 W insufficient; verify board space and thermal relief compatibility. |
| P6KE15CA | Legacy 600 W DO-15 package; wider VBR tolerance (14.3–15.8 V); higher ID (5 μA); not AEC-Q101 qualified. | Limited to commercial/industrial use; lacks automotive qualification and tighter leakage spec required for battery-powered nodes. | Choose P6KE15CA only for cost-sensitive non-automotive designs where AEC-Q101 and sub-1 μA leakage are not mandatory. |
Compared with BZW04-15-E3/54, SMBJ15CA offers higher surge capacity in a larger package, while P6KE15CA trades qualification and leakage performance for legacy compatibility and lower unit cost - making BZW04-15-E3/54 the optimal balance of automotive readiness, compact DO-41 fit, and precision clamping for 12–24 V systems.

FAQ
What is the clamping voltage of BZW04-15-E3/54 and how is it measured?
The clamping voltage (VC) of BZW04-15-E3/54 is 25.2 V, measured at a peak pulse current (IPPM) of 16 A using the standardized 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value represents the maximum voltage seen across the device during surge conduction and is critical for ensuring downstream components remain within their absolute maximum ratings. BZW04-15-E3/54 maintains this clamping performance across its full operating temperature range.
Is BZW04-15-E3/54 unidirectional or bidirectional, and how can I identify its polarity?
BZW04-15-E3/54 is a bidirectional TVS diode, meaning it provides symmetrical transient suppression in both forward and reverse directions. Unlike unidirectional variants (e.g., BZW04-15), it has no cathode band or polarity marking on the DO-41 package - both leads are functionally identical. This makes BZW04-15-E3/54 ideal for protecting AC-coupled or differential signal lines where polarity reversal may occur.
Does BZW04-15-E3/54 meet automotive qualification standards?
Yes, BZW04-15-E3/54 is AEC-Q101 qualified, as confirmed in Vishay's official documentation (Document Number 88316, Revision 16-Sep-2021). This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling (TCT), and highly accelerated temperature-humidity bias (HAST), validating its suitability for automotive powertrain, body electronics, and ADAS applications.
What is the maximum steady-state power dissipation of BZW04-15-E3/54?
The maximum steady-state power dissipation (PD) of BZW04-15-E3/54 is 1.5 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C. At ambient temperatures above 25 °C, this rating must be derated linearly per Figure 5 in the datasheet - for example, at TA = 75 °C, PD drops to approximately 0.75 W. This parameter governs continuous leakage-related heating, not transient surge handling.
How does the E3/54 suffix in BZW04-15-E3/54 affect packaging and compliance?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD201 Class 1A whisker resistance; "/54" specifies packaging in 13-inch paper tape and reel with 550 units per reel. This format ensures compatibility with automated SMT placement equipment and meets environmental compliance requirements for global electronics manufacturing. BZW04-15-E3/54 is not AEC-Q101 qualified - for that, the HE3 variant (e.g., BZW04-15HE3/54) must be selected.
