Product details
Overview
BZW04-136B-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal and power lines. It features a 136 V standoff voltage (VWM), 152–168 V breakdown range (VBR at 1 mA), 219 V maximum 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 and industrial I/O protection.
For engineers reviewing the BZW04-136B-E3/54 datasheet, BZW04-136B-E3/54 pinout, BZW04-136B-E3/54 application, or BZW04-136B-E3/54 equivalent, this device serves as a robust, AEC-Q101-qualified transient suppressor for bidirectional AC-coupled lines, high-impedance analog inputs, and ungrounded communication ports where polarity-agnostic surge suppression is required.
Technical Context
This bidirectional TVS operates symmetrically in both forward and reverse bias, delivering identical clamping behavior across polarities. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the 10/1000 μs pulse response enables effective suppression of lightning-induced surges and inductive switching transients.
The device is rated for continuous power dissipation of 1.5 W on an infinite heatsink and supports junction temperatures from –55 °C to +175 °C. Its 0.108 %/°C temperature coefficient of VBR ensures predictable voltage drift over automotive and industrial operating ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum continuous working voltage before conduction begins; defines safe operating margin for protected line. |
| VBR (min/max) | 152 V / 168 V at 1 mA - Confirmed breakdown threshold range; ensures reliable turn-on within spec under production tolerance. |
| VC @ IPPM | 219 V at 1.8 A - Clamped voltage during 10/1000 μs surge; limits downstream IC stress to safe levels. |
| PPPM | 400 W - Peak pulse power handling per single transient; validated for repetitive 0.01% duty cycle events. |
| IPPM | 1.8 A - Peak pulse current capability; determines minimum series impedance needed for full-power clamping. |
| TJ max. | +175 °C - Maximum junction temperature; supports under-hood automotive and high-ambient industrial use. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking - consistent with bidirectional function. Matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 wetting requirements.

Applications
| Automotive Sensor Protection | Industrial Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and position sensor outputs from load dump and ESD events in vehicle chassis modules. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and chassis ground, absorbing ±1 kV EFT and ISO 7637-2 pulses. Use Value: Maintains signal integrity during 13.5–16 V supply transients while preventing latch-up in 5 V tolerant transceivers. |
Use Scenario: Shielding 4–20 mA current loop inputs on PLC analog input cards from field wiring surges and ground potential differences. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected across input terminals, conducting only during >136 V transients to preserve normal 24 V loop operation. Use Value: Enables uninterrupted measurement during 1 kV/500 A surge events without requiring recalibration or signal interruption. |
| Telecom Line Interface Protection | Consumer Appliance Motor Control |
Use Scenario: Safeguarding RS-485 transceivers in building automation gateways exposed to induced surges on long twisted-pair runs. IC Role / Device Role / Timing Role: Symmetric transient suppressor bridging differential pair (A/B), clamping common-mode and differential transients equally. Use Value: Prevents permanent damage to half-duplex transceivers during 10/700 μs telecom surges while maintaining <10 pF capacitance. |
Use Scenario: Suppressing back-EMF spikes from brushed DC motors in smart home appliances (e.g., vacuum cleaners, blenders). IC Role / Device Role / Timing Role: Bidirectional clamp across motor terminals, diverting inductive kickback energy away from MCU GPIO and driver FETs. Use Value: Eliminates need for separate flyback diodes; reduces BOM count while sustaining 100,000+ motor switch cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Unidirectional; 130 V VWM; SMA package; 600 W PPPM | Requires explicit polarity assignment; unsuitable for AC-coupled or floating lines without redesign. | Select when higher pulse power is needed and board layout allows directional placement with cathode orientation. |
| 1.5KE150CA | DO-201 package; 150 V VWM; 1500 W PPPM; higher VC (243 V) | Larger footprint; higher clamping voltage increases risk to downstream 15 V logic rails. | Choose for legacy designs using DO-201 footprints or where 1.5 kW surge immunity outweighs space and voltage margin constraints. |

FAQ
What is the polarity configuration of BZW04-136B-E3/54?
BZW04-136B-E3/54 is a bidirectional TVS diode with symmetrical conduction characteristics in both directions. It has no cathode marking and functions identically regardless of lead orientation - ideal for AC-coupled or floating signal lines where polarity cannot be guaranteed. This distinguishes it from unidirectional variants like BZW04-136-E3/54.
Is BZW04-136B-E3/54 qualified for automotive use?
Yes, BZW04-136B-E3/54 carries the HE3 suffix variant for AEC-Q101 qualification, and the E3/54 packaging format is RoHS-compliant and rated for commercial grade. While the base E3 version is not AEC-Q101 certified, the HE3 variant (e.g., BZW04-136B-HE3/54) meets full automotive stress test requirements including temperature cycling, HTRB, and ESD.
What is the maximum clamping voltage of BZW04-136B-E3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-136B-E3/54 is 219 V at 1.8 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Can BZW04-136B-E3/54 replace a unidirectional TVS in an existing design?
BZW04-136B-E3/54 can replace a unidirectional TVS only if the circuit is inherently symmetric or AC-coupled - such as across transformer secondaries, differential pairs, or isolated power rails. In DC-biased circuits with defined polarity, substitution requires validation of reverse leakage, forward voltage drop, and clamping symmetry to avoid unintended conduction paths.
What is the thermal derating behavior of BZW04-136B-E3/54 above 25 °C ambient?
BZW04-136B-E3/54 follows standard thermal derating per Figure 2 in Vishay document 88316: its peak pulse power capability decreases linearly above 25 °C ambient, reaching ~50% of 400 W at 125 °C junction temperature. Continuous power dissipation (PD = 1.5 W) also derates to zero at +175 °C TJ.
