Product details
Overview
BZW04P136-E3/73 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, 400 W peak pulse power (10/1000 μs), and AEC-Q101 qualification - making it suitable for automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04P136-E3/73 datasheet, BZW04P136-E3/73 pinout, BZW04P136-E3/73 application, or BZW04P136-E3/73 equivalent, key selection criteria include its bi-directional clamping behavior, DO-41 package compatibility, low leakage (<1 μA at 136 V), and verified performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding 136 V, it avalanches to clamp line voltage at ≤219 V while diverting up to 1.8 A (10/1000 μs). Its glass-passivated junction ensures stable breakdown and fast response (<1 ns), with thermal derating defined from −55 °C to +175 °C junction temperature.
The bi-directional architecture enables symmetric protection on AC-coupled or floating lines without polarity concerns. It exhibits a temperature coefficient of breakdown voltage of +0.108 %/°C and maintains <1 μA reverse leakage at rated VWM, supporting high-impedance sensing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - maximum continuous working voltage before clamping begins; defines safe operating range for protected circuitry. |
| VC @ IPPM | 219 V at 1.8 A - clamped voltage during 10/1000 μs surge; limits stress on downstream ICs like microcontrollers or ADCs. |
| PPPM | 400 W - peak pulse power handling capability; supports IEC 61000-4-5 Level 4 surge immunity (4 kV/2 Ω). |
| IPPM | 1.8 A - peak pulse current corresponding to VC; used to size series impedance for energy limiting. |
| Leakage ID | <1 μA at 136 V - negligible DC loading on high-impedance signal paths such as sensor bridges or reference lines. |
| TJ max | +175 °C - extended junction temperature rating enables under-hood automotive use and high-reliability industrial deployment. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |

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 | Uni-directional; 130 V VWM, 219 V VC @ 1.8 A; SMB package (surface-mount) | Requires polarity-aware layout; better suited for space-constrained PCBs where through-hole DO-41 is impractical. | Select when board real estate is limited and uni-directional line topology (e.g., DC power rail) permits polarity assignment. |
| P6KE150A | Uni-directional; 150 V VWM, 243 V VC @ 1.5 A; DO-15 package; lower PPPM (600 W but 1.5×10 mm vs. 400 W in DO-41) | Higher clamping voltage reduces protection margin for 3.3 V/5 V ICs; legacy industrial design baseline. | Choose only if existing footprint compatibility with DO-15 is mandatory and 243 V clamping is acceptable for system-level margin. |
Compared with SMBJ130A and P6KE150A, BZW04P136-E3/73 offers bi-directional symmetry in a qualified DO-41 package - eliminating polarity concerns in AC or floating signal paths while delivering automotive-grade reliability not found in generic P6KE-series parts.

FAQ
What is the maximum clamping voltage of the BZW04P136-E3/73 under surge conditions?
The BZW04P136-E3/73 has a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current of 1.8 A with a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and ensures downstream circuitry remains within safe voltage limits during standardized surge events. The BZW04P136-E3/73 maintains this clamping performance across its full operating temperature range.
Is the BZW04P136-E3/73 suitable for automotive applications?
Yes, the BZW04P136-E3/73 is AEC-Q101 qualified and specifically designed for automotive environments. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification. Its 175 °C maximum junction temperature and stable clamping behavior make the BZW04P136-E3/73 appropriate for under-hood modules, body control units, and ADAS sensor interfaces.
Does the BZW04P136-E3/73 have polarity markings?
No, the BZW04P136-E3/73 is a bi-directional TVS diode and carries no polarity marking on its DO-41 package. Its symmetrical construction allows installation in either orientation - a key advantage for protecting AC-coupled signals, differential pairs, or floating bus lines where polarity assignment is undefined or variable. This eliminates orientation errors during manual or automated assembly of the BZW04P136-E3/73.
What is the standoff voltage (VWM) rating for the BZW04P136-E3/73?
The BZW04P136-E3/73 has a standoff voltage (VWM) of 136 V, meaning it remains in high-impedance state below this DC or RMS voltage level. At 136 V, reverse leakage current is guaranteed ≤1 μA, ensuring minimal loading on sensitive analog or communication circuits. This VWM rating directly supports 120 V AC line-derived supplies and 100 V+ DC bus protection in the BZW04P136-E3/73 application space.
How does the BZW04P136-E3/73 compare to standard P6KE-series TVS diodes?
The BZW04P136-E3/73 differs from legacy P6KE parts in three key ways: it is AEC-Q101 qualified (P6KE is commercial-grade only), uses glass passivation for superior long-term stability, and is bi-directional (P6KE150A is uni-directional). While both offer ~400 W pulse power, the BZW04P136-E3/73 delivers tighter parameter distribution and automotive-validated reliability - making it the preferred choice where functional safety or extended service life is required in the BZW04P136-E3/73 use case.
