Product details
Overview
BZW04P136B-E3/54 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 136 V standoff voltage (VWM), 219 V clamping voltage (VC) at 1.8 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 BZW04P136B-E3/54 datasheet, BZW04P136B-E3/54 pinout, BZW04P136B-E3/54 application, or BZW04P136B-E3/54 equivalent, key selection criteria include its bi-directional clamping symmetry, AEC-Q101 qualification, DO-41 package compatibility, low leakage (<1 µA at VWM), and temperature coefficient of breakdown voltage (0.108 %/°C).
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling single-device protection of AC-coupled or floating signal paths. Its glass-passivated junction ensures stable breakdown behavior and fast response (<1 ns), while the 10/1000 µs surge rating reflects standardized lightning and ESD transient immunity per ANSI/IEEE C62.35.
The device is rated for continuous operation from −55 °C to +175 °C junction temperature, with thermal derating above 25 °C ambient. Its 1.5 W steady-state power dissipation and 400 W non-repetitive peak pulse capability support intermittent surge events without thermal runaway under proper PCB layout and trace width design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - maximum continuous reverse/forward working voltage before clamping initiates |
| VBR min/max | 152 V / 176 V at 1 mA test current - guaranteed breakdown threshold range for reliable turn-on margin |
| VC @ IPPM | 219 V at 1.8 A - clamped voltage during full 400 W surge, defining protected circuit's worst-case overvoltage |
| IPPM | 1.8 A - peak pulse current supported with 10/1000 µs waveform, directly tied to PCB trace current handling |
| PPPM | 400 W - standardized surge power rating used for IEC 61000-4-5 level 4 compliance verification |
| TJ max | +175 °C - maximum junction temperature enabling use in under-hood automotive or high-ambient industrial environments |
| Temp. coeff. | 0.108 %/°C - predictable VBR drift over temperature, critical for precision clamp threshold stability |

Use Scenario: Protecting CAN, LIN, or analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed across differential or single-ended signal lines upstream of interface ICs. Use Value: Maintains signal integrity by limiting transients to ≤219 V while surviving repeated 12 V system surges up to 175 °C junction temperature. |
Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against field-wiring induced transients and relay coil flyback. IC Role / Device Role / Timing Role: Primary overvoltage suppression element mounted at connector entry point before optocoupler or Schmitt trigger input stage. Use Value: Clamps 400 W surges within 1 ns, preventing latch-up or damage to microcontroller GPIOs without adding propagation delay. |
| Telecom Line Interface | Consumer Power Adapter ESD Protection |
|
Use Scenario: Shielding RS-485/RS-422 data lines in base station backhaul equipment from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Bidirectional TVS paired with common-mode choke to suppress differential and common-mode transients simultaneously. Use Value: Symmetric clamping ensures equal protection on both A/B lines, preserving differential signaling integrity during 10/1000 µs surges. |
Use Scenario: Adding secondary-level surge immunity to USB-C or barrel jack inputs in wall adapters exposed to user-handling ESD and mains coupling. IC Role / Device Role / Timing Role: Final-stage clamp after primary MOV/fuse, absorbing residual energy that bypasses front-end filtering. Use Value: Low leakage (<1 µA) avoids standby current penalty; DO-41 form factor allows manual repair and cost-effective through-hole assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | DO-214AA (SMB) package; 130 V VWM, 219 V VC at 1.8 A; same PPPM but lower IFSM (100 A vs. 40 A uni-directional only) | Surface-mount alternative requiring PCB redesign; better suited for high-density layouts where axial leads are impractical | Select SMBJ130CA when space-constrained SMT assembly is required and thermal pad layout supports 1.5 W dissipation. |
| 1.5KE150CA | DO-201AD package; 150 V VWM, 243 V VC at 1.65 A; higher VC and larger footprint; 1500 W PPPM rating | Higher-power legacy alternative with looser clamping tolerance; used where 243 V clamping is acceptable for protected ICs | Choose 1.5KE150CA only if system-level surge tests confirm 243 V VC remains within downstream IC absolute maximum ratings. |
Compared with SMBJ130CA and 1.5KE150CA, BZW04P136B-E3/54 offers AEC-Q101 qualification and tighter VBR tolerance (±8.2 %) in a cost-optimized DO-41 package - making it preferred for automotive and industrial through-hole designs requiring validated reliability and precise clamping.

FAQ
What is the clamping voltage of BZW04P136B-E3/54 and how is it measured?
The clamping voltage (VC) of BZW04P136B-E3/54 is 219 V, measured at a peak pulse current (IPPM) of 1.8 A using the standardized 10/1000 µs double-exponential waveform per ANSI/IEEE C62.35. This value represents the maximum voltage seen across the device terminals during surge conduction and defines the upper voltage limit imposed on protected circuitry. The BZW04P136B-E3/54 achieves this clamping performance while maintaining symmetry in both directions due to its bi-directional construction.
Is BZW04P136B-E3/54 suitable for automotive applications?
Yes, BZW04P136B-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per the AEC-Q101 standard. Its operating junction temperature range of −55 °C to +175 °C and DO-41 package with matte tin leads meet automotive under-hood and control module requirements. The BZW04P136B-E3/54 is explicitly listed in Vishay's AEC-Q101 qualified devices table with HE3 suffix variants, confirming its suitability for automotive-grade designs.
What does the "B" suffix in BZW04P136B-E3/54 indicate?
The "B" suffix in BZW04P136B-E3/54 denotes the bi-directional configuration, meaning the device provides symmetrical transient suppression in both forward and reverse polarities - essential for protecting AC-coupled, differential, or floating signal lines. Unlike uni-directional variants (e.g., BZW04P136-E3/54), the BZW04P136B-E3/54 has no polarity marking and exhibits identical VBR, VC, and leakage characteristics in either direction, simplifying layout and eliminating orientation errors during assembly.
How does BZW04P136B-E3/54 compare to uni-directional TVS diodes in circuit protection?
BZW04P136B-E3/54 enables single-device protection of bidirectional signals (e.g., RS-485, CAN, audio lines) without requiring external polarity management, whereas uni-directional TVS diodes like BZW04P136-E3/54 must be oriented with cathode toward the positive rail and cannot clamp negative transients. The BZW04P136B-E3/54's symmetrical behavior reduces BOM count and layout complexity while maintaining identical 136 V VWM and 219 V VC specs - making it the preferred choice for floating or AC-coupled interfaces where polarity is undefined or alternating.
What is the maximum steady-state power dissipation for BZW04P136B-E3/54?
The maximum steady-state power dissipation (PD) for BZW04P136B-E3/54 is 1.5 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C, as specified in the Vishay datasheet (Document Number: 88316). This rating assumes ideal thermal conduction and must be derated linearly above 25 °C ambient per the power derating curve (Figure 5). In typical PCB applications with limited copper area, actual usable power is lower - design margins should account for thermal resistance from junction-to-ambient (RθJA) and expected ambient conditions to avoid exceeding the +175 °C TJ limit.
