Product details
Overview
BZW04P58HE3/73 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 58.1 V stand-off voltage (VWM), 92.0 V maximum clamping voltage (VC) at 4.3 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 μs waveform - suitable for automotive ECU input protection, industrial sensor interfaces, and telecom line surge suppression.
For engineers reviewing the BZW04P58HE3/73 datasheet, BZW04P58HE3/73 pinout, BZW04P58HE3/73 application, or BZW04P58HE3/73 equivalent, key selection considerations include its AEC-Q101 qualification, DO-41 (DO-204AL) package, bi-directional symmetry, low 0.104 %/°C VBR temperature coefficient, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 64.6 V (min) and 74.8 V (max) at 1 mA test current. Its clamping performance is validated under standardized 10/1000 μs surge waveforms, delivering consistent voltage limiting up to 92.0 V at 4.3 A without degradation.
The device uses glass passivated chip junction technology and matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. Its thermal design supports continuous operation from –55 °C to +175 °C junction temperature, with power derating above 25 °C ambient per Figure 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58.1 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 48 V nominal systems. |
| VC @ IPPM | 92.0 V - Clamped voltage at 4.3 A peak pulse current; ensures downstream ICs (e.g., CAN transceivers, ADC inputs) remain below absolute maximum ratings during surge events. |
| PPPM | 400 W - Peak pulse power handling with 10/1000 μs waveform; meets Level 4 IEC 61000-4-5 surge immunity (4 kV line-to-earth). |
| VBR Range | 64.6–74.8 V @ 1 mA - Tight breakdown tolerance enables predictable turn-on behavior across temperature and unit variation. |
| TJ Max | +175 °C - High junction temperature rating supports under-hood automotive placement and high-reliability industrial environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, temperature cycling, and HAST per AEC specification. |
| Package | DO-41 (DO-204AL) - Standard axial-leaded through-hole package with UL 94 V-0 molded epoxy; compatible with legacy PCB layouts and wave-solder processes. |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, cylindrical glass-passivated silicon die in flame-retardant epoxy housing. Dimensions: 5.2 mm diameter × 25.4 mm length minimum; lead diameter 0.66 mm; lead length ≥25.4 mm. No polarity marking - bi-directional symmetry eliminates cathode/anode orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional transient conduction path | Either lead serves as input/output terminal; no functional distinction - simplifies layout and eliminates orientation errors in PCB assembly. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable leakage performance (<1 μA at VWM) and long-term reliability under humidity and thermal stress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | Same VWM (58 V), but SMC (DO-214AB) surface-mount package; 600 W PPPM; higher IPPM (6.8 A); slightly higher VC (93.6 V). | Requires PCB redesign for SMD footprint; better suited for high-density consumer electronics where space is constrained. | Select SMBJ58CA when migrating to automated SMT assembly or needing higher surge margin without changing circuit topology. |
| 1.5KE56CA | Higher VWM (49.4 V), larger DO-201AD package; same 400 W rating; VC = 87.1 V at 4.6 A; non-AEC-Q101. | Lacks automotive qualification; used in cost-sensitive industrial power supplies where AEC compliance is not required. | Choose 1.5KE56CA only for commercial-grade applications with relaxed reliability and qualification requirements. |
Compared with SMBJ58CA and 1.5KE56CA, BZW04P58HE3/73 offers AEC-Q101 validation, tighter VBR tolerance (±7.7 % vs. ±10 %), and DO-41 compatibility with existing through-hole manufacturing - making it the preferred choice for automotive and industrial designs requiring proven field reliability and backward-compatible assembly.

FAQ
What is the maximum clamping voltage of BZW04P58HE3/73 under surge conditions?
The BZW04P58HE3/73 clamps to a maximum of 92.0 V when subjected to its rated 4.3 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across temperature and process variation, ensuring downstream components like microcontrollers or transceivers remain within safe operating limits during real-world surge events such as load dump or ESD coupling.
Is BZW04P58HE3/73 suitable for automotive applications?
Yes, BZW04P58HE3/73 is AEC-Q101 qualified and manufactured with HE3 suffix - indicating compliance with JESD201 Class 2 whisker resistance and full automotive reliability testing. It is widely deployed in body control modules, infotainment power rails, and sensor interfaces where sustained operation at 175 °C junction temperature and immunity to repetitive surges are mandatory.
How does the bi-directional nature of BZW04P58HE3/73 affect circuit design?
The bi-directional architecture of BZW04P58HE3/73 means it conducts identically in both polarities, eliminating the need for polarity-aware placement or external biasing. This simplifies PCB layout, reduces BOM count, and improves robustness in AC-coupled or floating signal paths - such as RS-485 buses or transformer-isolated power feeds - where voltage reversals are inherent.
What is the meaning of the 'HE3' suffix in BZW04P58HE3/73?
The 'HE3' suffix in BZW04P58HE3/73 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. Unlike standard 'E3' parts, 'HE3' devices undergo additional stress screening for automotive use, including extended temperature cycling and high-acceleration mechanical shock tests - confirming suitability for under-hood and safety-critical subsystems.
Can BZW04P58HE3/73 replace uni-directional TVS diodes in existing designs?
BZW04P58HE3/73 can replace uni-directional TVS diodes only if the circuit is inherently symmetrical or referenced to ground on both sides - such as differential data lines or AC power inputs. It must not be substituted in DC-biased unidirectional paths (e.g., 12 V supply rail with cathode-to-rail configuration) without verifying that reverse conduction does not disrupt biasing or cause unintended current paths in the system.
