Product details
Overview
5KP5.0-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.0 V breakdown voltage (VBR) at 50 mA, 5000 W peak pulse power (10/1000 μs), 543 A maximum peak pulse current (IPPM), and clamps to ≤9.2 V at rated surge. It is used in automotive power supplies, industrial motor drives, and telecom interface protection.
For engineers reviewing the 5KP5.0-E3/73 datasheet, 5KP5.0-E3/73 pinout, 5KP5.0-E3/73 application, or 5KP5.0-E3/73 equivalent, key selection criteria include unidirectional polarity, P600 package thermal performance, clamping voltage margin versus protected IC VCC, IEC 61000-4-5 surge compliance capability, and AEC-Q101 qualification status for automotive deployment.
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for high-energy transient suppression. Its low incremental surge resistance and fast response time (<1 ns) enable effective clamping of inductive switching spikes and lightning-induced surges on 5 V supply rails.
It operates within –55 °C to +175 °C junction temperature range and supports repetitive surge duty cycles up to 0.01 % with 10/1000 μs waveform. The device is RoHS-compliant (E3 suffix), meets JESD 201 Class 1A whisker test, and is rated for 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before conduction begins; sets minimum system rail margin. |
| VBR @ IT = 50 mA | 6.4–7.0 V - Breakdown onset range; defines reliable turn-on threshold under standardized test conditions. |
| IPPM (10/1000 μs) | 543 A - Peak surge current handling capacity; determines survivability against IEC 61000-4-5 Level 4 (4 kV) transients. |
| VC @ IPPM | ≤9.2 V - Clamped voltage during full-rated surge; must remain below protected device absolute maximum rating. |
| PPPM | 5000 W - Peak pulse power rating; enables robust protection without crowbar circuitry in 5 V SMPS outputs. |
| TJ max. | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
| Polarity | Unidirectional - Cathode-banded configuration; suitable for DC rail protection only, not AC or bidirectional signals. |
Pinout & Package
5KP5.0-E3/73 is housed in a P600 axial-leaded package: molded epoxy body over glass-passivated junction, UL 94 V-0 rated, matte tin-plated leads solderable per J-STD-002. Polarity is marked by a cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | DC input / line side | Connected to protected power rail or signal source; conducts during forward surge events. |
| Cathode | DC output / load side | Marked by color band; ties to ground or return path; defines unidirectional clamping direction. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against severe transients without external crowbar circuitry in 5 V power systems. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per stress test requirements. |
| Low clamping voltage (≤9.2 V) | Maintains safe margin below typical 12 V tolerant logic ICs and microcontrollers powered from regulated 5 V rails. |
| P600 package thermal robustness | Supports 8.0 W continuous power dissipation with proper heatsinking-critical for sustained overvoltage recovery in industrial controls. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Lower peak power (600 W), smaller SMB package, same VWM/VBR tolerance. | Not suitable for IEC 61000-4-5 Level 4; limited to board-level ESD and lower-energy transients. | Select when space-constrained layouts prioritize footprint over surge energy handling. |
| 1.5KE5.0A | Same P600 package and 5000 W rating, but older 1.5 kW series; higher VC (10.5 V) and no AEC-Q101 qualification. | Lacks automotive qualification; less stable clamping under repeated surge stress. | Choose only for cost-sensitive industrial applications where AEC-Q101 is not mandated. |
Compared with SMBJ5.0A-E3/52 and 1.5KE5.0A, the 5KP5.0-E3/73 delivers superior surge robustness (5000 W), automotive-grade reliability (AEC-Q101), and tighter clamping (≤9.2 V), making it the preferred choice for mission-critical 5 V rail protection where thermal margin and transient severity are highest.

FAQ
What is the clamping voltage of the 5KP5.0-E3/73 under full-rated surge conditions?
The 5KP5.0-E3/73 clamps to a maximum of 9.2 V when subjected to its rated 543 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and ensures compatibility with 5 V logic systems where absolute maximum ratings typically begin at 7 V or higher-providing essential headroom for transient suppression without damaging downstream ICs.
Is the 5KP5.0-E3/73 suitable for automotive applications?
Yes, the 5KP5.0-E3/73 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment power supplies. Its –55 °C to +175 °C operating junction temperature range, robust P600 package, and validated performance under temperature cycling and humidity bias make it appropriate for under-hood and cabin-mounted systems requiring long-term reliability.
How does the 5KP5.0-E3/73 differ from the 5KP5.0A variant?
The 5KP5.0-E3/73 is a specific tape-and-reel packaging variant of the 5KP5.0A base device: "E3" denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance, while "/73" indicates a 7-inch reel packaging option (800 pcs/reel). Electrically and thermally, the 5KP5.0-E3/73 is identical to 5KP5.0A and shares all electrical specifications, including VWM, VBR, IPPM, and VC.
Can the 5KP5.0-E3/73 be used in bidirectional signal protection?
No, the 5KP5.0-E3/73 is unidirectional only, with polarity indicated by a cathode band. It is designed exclusively for DC rail protection where the anode connects to the power source and the cathode to ground. For bidirectional signal line protection (e.g., USB, RS-485), a symmetric TVS array or dedicated bidirectional device such as SMAJ5.0A must be selected instead.
What is the maximum steady-state power dissipation for the 5KP5.0-E3/73?
The 5KP5.0-E3/73 has a maximum steady-state power dissipation (PD) of 8.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C, per Figure 5 in the Vishay datasheet. In practical PCB layouts, derating is required based on copper area, ambient temperature, and airflow-typically limiting continuous dissipation to 2–4 W without forced cooling.
