Product details
Overview
BZW04-5V8HE3/54 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 5.8 V standoff voltage (VWM), 6.45–7.14 V breakdown voltage (VBR) at 10 mA, 400 W peak pulse power (10/1000 μs), 10.5 V clamping voltage at 38 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BZW04-5V8HE3/54 datasheet, BZW04-5V8HE3/54 pinout, BZW04-5V8HE3/54 application, or BZW04-5V8HE3/54 equivalent, this device serves as a robust, RoHS-compliant, bidirectional surge protector for low-voltage sensor interfaces, automotive control modules, and industrial I/O protection where fast response (<1 ns), low clamping ratio, and high surge current tolerance are critical.
Technical Context
This TVS operates bidirectionally with symmetrical breakdown characteristics in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage performance and long-term reliability under repetitive surge stress.
The device delivers 400 W peak pulse power per the 10/1000 μs waveform standard (IEC 61000-4-5), with a clamping voltage of 10.5 V at 38 A - yielding a clamping ratio (VC/VBR) of ~1.55 - and exhibits a low temperature coefficient of VBR (0.057 %/°C), minimizing drift across automotive operating temperatures (−55 °C to +175 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.8 V - maximum continuous reverse working voltage before conduction begins; defines safe operating margin for 5 V systems. |
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA - precise breakdown threshold ensuring predictable turn-on during overvoltage events. |
| VC @ IPPM | 10.5 V at 38 A - clamping voltage limits downstream IC stress during 400 W transient surges. |
| PPPM | 400 W - peak pulse power rating per 10/1000 μs waveform, supporting IEC 61000-4-5 Level 4 immunity. |
| ID @ VWM | 1000 μA - maximum reverse leakage at 5.8 V, low enough to avoid loading sensitive 5 V logic or analog inputs. |
| TJ max. | +175 °C - extended junction temperature rating enables use in under-hood automotive environments. |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test requirements including HTOL, TC, and ESD. |
Pinout & Package
DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads; no polarity marking - consistent with bidirectional function.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Identical electrical behavior in both directions; either lead may connect to protected line or ground reference. |
| Lead 1 / Lead 2 | Device terminals | Leads serve as mechanical attachment and thermal path; solderable per J-STD-002; 275 °C max dip for 10 s. |
Key Features
| Feature | Design Value |
|---|---|

| 400 W peak pulse power (10/1000 μs) | Supports robust protection against lightning-induced surges and inductive switching spikes in automotive and industrial settings. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body electronics, and ADAS modules requiring zero-defect reliability. |
| Low clamping voltage (10.5 V) | Keeps protected 5 V ICs (e.g., microcontrollers, CAN transceivers) safely below absolute maximum ratings during transients. |
| UL 94 V-0 molding compound | Provides flame-retardant encapsulation required for safety-critical automotive and industrial assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Unidirectional; 5.0 V VWM; SMB package (surface-mount); 600 W PPPM; higher VC (9.2 V @ 43.3 A). | Requires polarity-aware layout; better suited for DC-biased rails where unidirectional clamping suffices. | Select when board space constraints favor SMD and system ground reference is fixed polarity. |
| 1.5KE6.8A | Unidirectional; 6.8 V VWM; DO-201 package; 1500 W PPPM; higher VC (10.5 V @ 143 A); larger footprint. | Higher energy handling but slower response due to larger junction area; not AEC-Q101 qualified. | Choose only for non-automotive, high-energy industrial surge scenarios where qualification is not required. |
Compared with SMBJ5.0A-E3/52 and 1.5KE6.8A, BZW04-5V8HE3/54 offers bidirectional symmetry in a compact DO-41 through-hole package with AEC-Q101 certification - making it uniquely suitable for automotive sensor interfaces and floating signal lines where polarity independence and qualification are mandatory.
