Product details
Overview
BZW04-128-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 128 V standoff voltage (VWM), 143–158 V breakdown range (VBR at 1 mA), 207 V clamping voltage (VC) at 2.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the BZW04-128-E3/54 datasheet, BZW04-128-E3/54 pinout, BZW04-128-E3/54 application, or BZW04-128-E3/54 equivalent, key selection criteria include its bidirectional polarity, AEC-Q101 qualification, 175 °C maximum junction temperature, low 0.108 %/°C VBR temperature coefficient, and compatibility with lead-free reflow and wave soldering per J-STD-002.
Technical Context
This device operates as a voltage-clamped surge protector using an avalanche breakdown mechanism, with symmetrical bidirectional conduction enabling protection against both positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable leakage performance and long-term reliability under repetitive surge stress.
The BZW04-128-E3/54 delivers consistent clamping behavior across temperature (−55 °C to +175 °C) and maintains ≤1.0 μA reverse leakage at VWM, supporting high-impedance signal integrity in sensor front-ends and communication lines. Its 10/1000 μs surge response is validated per ANSI/IEEE C62.35 standards and rated for 0.01 % duty cycle repetition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 128 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working margin for protected circuitry. |
| VBR min/max | 143 V / 158 V at 1 mA - Verified breakdown threshold range ensuring predictable turn-on during surges without premature triggering. |
| VC @ IPPM | 207 V at 2.0 A - Clamped voltage during 10/1000 μs transient; limits downstream voltage stress to safe levels for connected ICs. |
| PPPM | 400 W - Peak pulse power handling capability; supports high-energy ESD and inductive-switching events in automotive and industrial environments. |
| TJ max | +175 °C - Enables operation in under-hood automotive and high-temperature industrial enclosures without thermal derating penalties. |
| Leakage ID | ≤1.0 μA at VWM - Minimal standby current draw preserves signal integrity and battery life in always-on sensor nodes. |
| Temp. Coeff. | 0.108 %/°C - Low VBR drift ensures stable clamping performance across wide ambient temperature ranges. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; matte tin-plated terminals compliant with J-STD-002 solderability and JESD22-B102 wetting balance testing. Bidirectional construction means no cathode marking - both leads are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals serve identical roles in bidirectional clamping; no polarity orientation required during PCB placement. |
| Lead 1 | Connection to protected line | Directly interfaces with signal or power rail needing surge suppression; requires low-inductance layout to preserve response speed. |
| Lead 2 | Connection to reference (GND or return) | Completes clamping loop; must be routed to low-impedance ground plane to minimize voltage overshoot during surge events. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR and low leakage over 10+ years in humid or thermally cycled environments. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces. |
| 400 W peak pulse power (10/1000 μs) | Withstands ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 surges without degradation. |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed industrial control cabinets and automotive junction boxes. |
| JESD 201 Class 1A whisker resistance | E3 suffix guarantees no tin whisker growth under thermal cycling, critical for long-life embedded systems. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Unidirectional; 130 V VWM; SMA package; 600 W PPPM; higher IPPM (3.3 A) | Requires correct polarity orientation; better suited for DC power rail protection than AC-coupled signal lines | Select when higher surge current capacity is needed and board layout allows unidirectional placement with cathode alignment. |
| P6KE130A | Unidirectional; 130 V VWM; DO-15 package; 600 W PPPM; larger footprint and lower thermal mass than DO-41 | Higher power dissipation capability but slower thermal recovery; less suitable for space-constrained automotive modules | Choose for legacy designs using DO-15 footprints or where 600 W rating justifies larger board area and weight. |
Compared with SMBJ130A and P6KE130A, the BZW04-128-E3/54 offers bidirectional symmetry essential for AC signal lines, compact DO-41 form factor ideal for dense automotive PCBs, and AEC-Q101 qualification not present in standard P6KE or SMBJ series - making it the preferred choice for new automotive and industrial sensor interface designs.

FAQ
What is the polarity configuration of BZW04-128-E3/54?
The BZW04-128-E3/54 is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative voltage transients. Unlike unidirectional variants, it has no cathode marking and can be installed without regard to orientation - a critical advantage for protecting AC-coupled or differential signal paths where polarity is undefined.
Is BZW04-128-E3/54 qualified for automotive use?
Yes, BZW04-128-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life, temperature cycling, and ESD robustness required for automotive electronic modules. Its DO-41 package, 175 °C TJ max, and JESD201 Class 1A whisker resistance make it suitable for engine bay, chassis, and infotainment applications.
What is the clamping voltage of BZW04-128-E3/54 under surge conditions?
The BZW04-128-E3/54 clamps to a maximum of 207 V when subjected to its rated 2.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across temperature and ensures downstream components - such as automotive-grade MCUs or RS-485 transceivers - remain within their absolute maximum voltage ratings during transient events.
How does the E3/54 suffix affect BZW04-128-E3/54 packaging and compliance?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD201 Class 1A whisker resistance; "54" denotes the preferred package code for 13-inch paper tape and reel delivery (550 units per reel). This format supports high-speed pick-and-place assembly and meets IPC/JEDEC moisture sensitivity level (MSL) requirements for standard reflow profiles.
Can BZW04-128-E3/54 replace older P6KE-series TVS diodes?
BZW04-128-E3/54 is not a direct drop-in replacement for P6KE130A due to differences in package (DO-41 vs. DO-15), polarity (bidirectional vs. unidirectional), and thermal characteristics. While both offer similar VWM and PPPM, substituting requires verifying PCB footprint, polarity constraints, and surge test compliance - especially in automotive designs where AEC-Q101 validation is mandatory.
