Product details
Overview
BZW04P53HE3/73 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 53.0 V stand-off voltage (VWM), 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform), making it suitable for safeguarding automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching transients.
For engineers reviewing the BZW04P53HE3/73 datasheet, BZW04P53HE3/73 pinout, BZW04P53HE3/73 application, or BZW04P53HE3/73 equivalent, key selection considerations include its AEC-Q101 qualification, DO-204AL (DO-41) package, bi-directional polarity, 0.67 µA max reverse leakage at VWM, and temperature coefficient of 0.104 %/°C - all critical for reliable operation in automotive-grade designs.
Technical Context
This bi-directional TVS diode operates symmetrically in both forward and reverse bias, enabling clamping of positive and negative transients without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, while the 10/1000 µs waveform rating reflects real-world lightning and load-dump surge immunity per IEC 61000-4-5.
The device is rated for continuous operation from –55 °C to +175 °C junction temperature and supports soldering up to 275 °C for 10 s (JESD 22-B106). Its 1.5 W steady-state power dissipation (PD) and 0.104 %/°C VBR temperature coefficient ensure predictable performance across thermal extremes in engine control units and motor drive feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - Maximum continuous working voltage before clamping begins; defines safe operating margin below system rail. |
| VC @ IPPM | 85.0 V at 4.7 A - Clamped voltage during 10/1000 µs surge; limits stress on downstream ICs like CAN transceivers. |
| PPPM | 400 W - Peak pulse power handling capability; meets Level 4 IEC 61000-4-5 surge immunity requirements. |
| IPPM | 4.7 A - Peak pulse current supported at rated VC; determines minimum series impedance needed for compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ53A-E3/52 | DO-214AA (SMB) package; 53.0 V VWM; 87.1 V VC @ 4.6 A; same PPPM (400 W); unidirectional only. | Requires polarity-aware PCB layout; higher thermal resistance than DO-41 in free-air conditions. | Select when board space is constrained and unidirectional protection suffices with existing cathode-marked routing. |
| 1.5KE56A | DO-201AD package; 56.0 V VWM; 93.6 V VC @ 4.3 A; 1500 W PPPM; unidirectional; no AEC-Q101 qualification. | Higher clamping voltage reduces protection margin; lacks automotive qualification and tighter leakage spec. | Acceptable for cost-sensitive industrial applications where AEC-Q101 is not mandated and 93.6 V clamping is within system tolerance. |

FAQ
What is the clamping voltage of BZW04P53HE3/73 under a 10/1000 µs surge?
The BZW04P53HE3/73 clamps to a maximum of 85.0 V when subjected to its rated 4.7 A peak pulse current (IPPM) using the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream circuit protection margin calculations in designs using BZW04P53HE3/73.
Is BZW04P53HE3/73 suitable for automotive applications?
Yes, BZW04P53HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, DO-41 package with matte tin leads, and operation up to +175 °C junction temperature - meets the environmental and reliability requirements for engine control units, body electronics, and ADAS sensor interfaces where BZW04P53HE3/73 is deployed.
Does BZW04P53HE3/73 have polarity markings?
No, BZW04P53HE3/73 is a bi-directional TVS diode and carries no polarity marking on the package. Its symmetrical electrical characteristics allow installation in either orientation on the PCB, simplifying layout for AC-coupled or differential signal paths where polarity awareness would otherwise complicate routing - a key advantage of BZW04P53HE3/73 over unidirectional alternatives.
What is the maximum reverse leakage current of BZW04P53HE3/73 at its stand-off voltage?
At its 53.0 V stand-off voltage (VWM) and ambient temperature of 25 °C, BZW04P53HE3/73 exhibits a maximum reverse leakage current (ID) of 0.67 µA. This ultra-low leakage ensures minimal loading on high-impedance sensor bias networks and preserves accuracy in precision analog front-ends where BZW04P53HE3/73 is commonly applied.
How does the temperature coefficient affect BZW04P53HE3/73's breakdown voltage?
The BZW04P53HE3/73 has a maximum temperature coefficient of 0.104 %/°C for its breakdown voltage (VBR). This means VBR increases by up to 0.055 V per °C rise above 25 °C - a predictable drift that must be accounted for in high-temperature applications such as under-hood automotive modules, where BZW04P53HE3/73 maintains functional integrity up to +175 °C junction temperature.
