Product details
Overview
BZW04P136HE3/54 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 stand-off voltage (VWM), 219 V clamping voltage (VC) at 1.8 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the BZW04P136HE3/54 datasheet, BZW04P136HE3/54 pinout, BZW04P136HE3/54 application, or BZW04P136HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package compatibility, bi-directional surge handling, and low leakage (<1 μA at VWM) for high-impedance circuits.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, delivering consistent clamping performance without polarity dependency. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, critical for repeatable transient suppression under repetitive surge conditions (0.01% duty cycle).
The device is rated for 175 °C maximum junction temperature and exhibits a +0.108 %/°C temperature coefficient of breakdown voltage (VBR), enabling predictable voltage drift across automotive and industrial thermal ranges. It meets JESD22-B102 solderability and JESD201 Class 2 whisker resistance (HE3 suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin for protected circuitry. |
| VC @ IPPM | 219 V at 1.8 A - Clamped voltage during 10/1000 μs surge; determines worst-case stress on downstream components. |
| PPPM | 400 W - Peak pulse power handling capability; supports EN 61000-4-5 Level 4 (4 kV) surge immunity testing. |
| ID @ VWM | <1 μA - Reverse leakage current at stand-off voltage; preserves signal integrity in high-impedance sensor or data lines. |
| TJ max. | 175 °C - Maximum junction temperature; enables operation in under-hood automotive and industrial environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC standard. |

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 (400 W) but higher capacitance (~100 pF vs. ~30 pF for BZW04P136HE3/54). | Preferred for surface-mount boards with space constraints; less suitable for high-frequency analog lines due to higher junction capacitance. | Select SMBJ130CA only when SMT assembly is mandatory and signal bandwidth permits higher capacitance. |
| P6KE150CA | DO-15 package; 150 V VWM; 243 V VC at 1.6 A; lower PPPM derating above 75 °C; no AEC-Q101 qualification. | Used in cost-sensitive industrial power supplies where automotive qualification is not required. | Choose P6KE150CA for non-automotive applications needing higher VWM margin but accepting reduced thermal robustness and reliability validation. |
Compared with SMBJ130CA and P6KE150CA, BZW04P136HE3/54 offers AEC-Q101 qualification, lower leakage, tighter VBR tolerance, and optimized thermal performance in the DO-41 form factor - making it the preferred choice for automotive and high-reliability through-hole designs requiring validated long-term stability.

FAQ
What is the clamping voltage of BZW04P136HE3/54 under a 10/1000 μs surge?
The BZW04P136HE3/54 clamps to a maximum of 219 V when subjected to a 10/1000 μs waveform at 1.8 A peak pulse current (IPPM), as specified in the Vishay datasheet (Document Number: 88316). This value defines the upper voltage limit imposed on protected circuitry during standardized surge events and is critical for ensuring downstream ICs remain within absolute maximum ratings. The BZW04P136HE3/54 maintains this clamping performance across its full operating temperature range.
Is BZW04P136HE3/54 suitable for automotive applications?
Yes, BZW04P136HE3/54 is AEC-Q101 qualified (HE3 suffix), having passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge per the AEC standard. It is explicitly intended for automotive use cases such as sensor interface protection, body control modules, and infotainment power rails. The BZW04P136HE3/54 also supports operation up to 175 °C junction temperature, meeting under-hood thermal requirements.
What does the "HE3" suffix indicate in BZW04P136HE3/54?
The "HE3" suffix in BZW04P136HE3/54 denotes two key attributes: RoHS compliance (E3) and AEC-Q101 qualification (H). Specifically, E3 confirms compliance with Directive 2011/65/EU and JESD201 Class 1A whisker testing, while the "H" prefix signals full AEC-Q101 qualification - verified by Vishay for automotive-grade reliability. This distinguishes BZW04P136HE3/54 from commercial-grade variants like BZW04P136E3/54.
How does BZW04P136HE3/54 differ from uni-directional TVS diodes?
BZW04P136HE3/54 is bi-directional, meaning it provides symmetrical clamping in both forward and reverse polarities - essential for protecting AC-coupled or differential signal lines (e.g., RS-485, CAN) where voltage transients can swing positive or negative. Unlike uni-directional TVS diodes, it has no cathode marking and delivers identical VBR, VC, and IPPM characteristics in either direction. The BZW04P136HE3/54 thus eliminates polarity installation errors and simplifies layout in bidirectional interfaces.
What is the maximum reverse leakage current for BZW04P136HE3/54 at its stand-off voltage?
The maximum reverse leakage current (ID) for BZW04P136HE3/54 is 1.0 μA at its 136 V stand-off voltage (VWM), measured at TA = 25 °C. This ultra-low leakage preserves signal fidelity in high-impedance circuits such as precision sensor front-ends or battery-monitoring paths. The BZW04P136HE3/54 maintains leakage below 5 μA even at elevated temperatures (125 °C), ensuring stable performance across industrial operating ranges.
