Product details
Overview
BZW04P23-E3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode in DO-204AL (DO-41) package, designed for clamping ESD and surge transients on signal/power lines. It features 400 W peak pulse power (10/1000 µs), 23.1 V stand-off voltage (VWM), 37.5 V maximum clamping voltage (VC) at 10.7 A peak pulse current, and operates across –55 °C to +175 °C junction temperature - deployed in automotive sensor interface protection.
For engineers reviewing the BZW04P23-E3/54 datasheet, BZW04P23-E3/54 pinout, BZW04P23-E3/54 application, or BZW04P23-E3/54 equivalent, key selection criteria include verified bi-directional clamping performance, AEC-Q101 qualification, DO-41 mechanical compatibility, and precise VWM/VC margin for 24 V system rail protection.
Technical Context
This bi-directional TVS diode uses a glass passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of inductive switching spikes and lightning-induced surges. Its symmetrical breakdown behavior ensures identical clamping in both polarities without polarity marking.
The device complies with AEC-Q101 stress testing for automotive applications and meets UL 94 V-0 flammability requirements via molded epoxy encapsulation. Thermal derating follows standard curves up to TJ = 175 °C, with 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 23.1 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin below 24 V nominal rail. |
| VBR (min/max) | 25.7 V / 29.7 V at 1 mA - Verified breakdown threshold range ensures consistent turn-on across production lots. |
| VC @ IPPM | 37.5 V at 10.7 A (10/1000 µs) - Clamping voltage defines worst-case overvoltage seen by protected IC during surge event. |
| PPPM | 400 W - Peak pulse power handling capacity determines survivability against standardized surge waveforms. |
| IPPM | 10.7 A - Peak pulse current rating directly correlates with energy absorption (E = ∫v·i dt ≈ 400 W × 1000 µs). |
| TJ max. | +175 °C - High junction temperature rating supports under-hood automotive placement without thermal derating penalties. |
| AEC-Q101 | Qualified - Confirmed reliability for automotive electronics per stress test requirements including HTOL, TC, UHAST. |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, epoxy-molded, matte tin-plated leads compliant with J-STD-002 and JESD22-B102. No polarity marking - bi-directional operation confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Bi-directional terminals conduct equally in either polarity; no cathode band - enables blind-mount PCB layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA package; 24 V VWM, 38.9 V VC @ 10.3 A; same PPPM but lower IPPM (10.3 A vs. 10.7 A). | Surface-mount alternative requiring PCB redesign; slightly higher clamping voltage reduces margin for 24 V systems. | Select when SMT assembly is mandatory and board space is constrained; verify thermal pad layout for 1.5 W dissipation. |
| 1.5KE24CA | DO-201AD package; 24 V VWM, 38.9 V VC @ 10.3 A; 1500 W PPPM but larger footprint and higher leakage. | Higher-power through-hole option with 3.7× larger case volume; not AEC-Q101 qualified. | Choose only for non-automotive industrial use where surge energy exceeds 400 W; avoid in space-constrained or automotive designs. |
Compared with SMBJ24CA and 1.5KE24CA, BZW04P23-E3/54 offers AEC-Q101 qualification, DO-41 compatibility with legacy through-hole tooling, and tighter VC margin (37.5 V) critical for 24 V rail protection - making it the preferred choice for automotive and high-reliability industrial deployments.

FAQ
What is the clamping voltage of BZW04P23-E3/54 under a 10/1000 µs surge?
The maximum clamping voltage (VC) of BZW04P23-E3/54 is 37.5 V at 10.7 A peak pulse current with a 10/1000 µs waveform. This value is measured per IEC 61000-4-5 test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The BZW04P23-E3/54 maintains this clamping performance across its full operating temperature range.
Is BZW04P23-E3/54 suitable for automotive applications?
Yes, BZW04P23-E3/54 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C, making it suitable for under-hood and body-control module applications. Its glass-passivated junction, UL 94 V-0 epoxy, and bi-directional symmetry support reliable performance in automotive ECU, sensor, and infotainment systems. The BZW04P23-E3/54 meets stringent automotive reliability requirements without derating.
What does the "E3/54" suffix indicate in BZW04P23-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD201 Class 1A whisker resistance. The "/54" indicates packaging in 13-inch paper tape and reel, with 550 units per reel. This packaging format supports automated pick-and-place insertion and ensures traceable, moisture-safe handling per J-STD-020. The BZW04P23-E3/54 is shipped in this industry-standard configuration.
How does BZW04P23-E3/54 differ from uni-directional variants like BZW04P23?
BZW04P23-E3/54 is the bi-directional version (denoted by the "B" in datasheet part numbering), with symmetrical breakdown in both polarities and no cathode marking. In contrast, uni-directional BZW04P23 has a cathode band and conducts only in reverse bias. Both share identical VWM (23.1 V), VC (37.5 V), and PPPM (400 W), but BZW04P23-E3/54 is selected where AC-coupled or polarity-agnostic protection is required.
What is the maximum reverse leakage current for BZW04P23-E3/54 at VWM?
The maximum reverse leakage current (ID) for BZW04P23-E3/54 is 1.0 µA at VWM = 23.1 V and TA = 25 °C. This low leakage ensures minimal power loss in standby mode and avoids false triggering in high-impedance sensing circuits. The BZW04P23-E3/54 maintains this specification across its full temperature range with predictable coefficient drift.
