Product details
Overview
5KP5.0AHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, rated for 5.0 V stand-off voltage, 6.4–7.0 V breakdown at 50 mA, and 5000 W peak pulse power (10/1000 μs). It delivers 543 A peak pulse current and clamps to 9.2 V at that current, with AEC-Q101 qualification for automotive-grade reliability in power supply output protection.
For engineers reviewing the 5KP5.0AHE3/54 datasheet, 5KP5.0AHE3/54 pinout, 5KP5.0AHE3/54 application, or 5KP5.0AHE3/54 equivalent, key selection criteria include unidirectional polarity, 5.0 V VWM, 9.2 V clamping voltage at 543 A, P600 package thermal performance, and AEC-Q101 qualification for under-hood automotive systems.
Technical Context
This TVS diode operates as a crowbar-replacement overvoltage protector on DC power rails-triggering into low-impedance conduction when reverse voltage exceeds its 6.4–7.0 V breakdown range. Its glass-passivated P600 junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 0.01% duty-cycle transients.
Designed for switching power supply outputs, it withstands 5000 W pulses without failure while allowing downstream fuses or breakers time to clear faults. The HE3 suffix confirms AEC-Q101 qualification, matte tin plating per J-STD-002, and JESD 201 Class 2 whisker resistance-critical for automotive ECU and infotainment power rail protection.

Pinout & Package
5KP5.0AHE3/54 uses the axial-lead P600 package: molded epoxy body (UL 94 V-0), 9.5 mm length, 0.375" lead spacing, matte tin-plated leads solderable per J-STD-002. Polarity is marked by cathode band; no active pin numbering applies-cathode and anode are defined by band location.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VRM exceeded |
| Anode (unbanded end) | Reference node | Typically tied to system ground or low-impedance return path for clamping action |

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 | Lower PPPM (600 W), SMC package, 1000 W peak pulse rating, smaller footprint | Suitable for space-constrained consumer PCBs but insufficient for automotive load dump | Select SMBJ5.0A only for non-automotive, low-energy surge environments where board area is critical |
| 1.5KE5.0A | Same P600 package, 1500 W PPPM, lower IPPM (395 A), higher VC (10.8 V) | Acceptable for industrial controls with moderate surge exposure but lacks AEC-Q101 qualification | Choose 1.5KE5.0A for cost-sensitive industrial designs where automotive qualification is not required |

FAQ
What is the clamping voltage of the 5KP5.0AHE3/54 at its rated peak pulse current?
The 5KP5.0AHE3/54 clamps to a maximum of 9.2 V at its rated peak pulse current of 543 A (10/1000 μs waveform). This low clamping voltage ensures protected 5 V logic circuits remain within safe operating limits during surge events, directly supporting design margins for microcontrollers and interface ICs.
Is the 5KP5.0AHE3/54 suitable for automotive applications?
Yes, the 5KP5.0AHE3/54 is AEC-Q101 qualified and features HE3 suffix indicating compliance with automotive reliability standards-including temperature cycling, mechanical shock, and whisker resistance. Its 175 °C max junction temperature and P600 thermal mass make it appropriate for under-hood ECU and ADAS power rail protection.
What does the "HE3" suffix mean in 5KP5.0AHE3/54?
The "HE3" suffix in 5KP5.0AHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions and confirms suitability for automotive and high-reliability industrial use.
How does the 5KP5.0AHE3/54 compare to standard Zener diodes for overvoltage protection?
Unlike standard Zeners, the 5KP5.0AHE3/54 is optimized for transient suppression-not regulation-with 5000 W peak pulse power, sub-ns response, and low dynamic impedance during surges. Its 9.2 V clamping at 543 A far exceeds the energy-handling capability of any Zener, making it a dedicated TVS solution rather than a voltage reference.
What is the maximum reverse leakage current for the 5KP5.0AHE3/54 at its stand-off voltage?
The 5KP5.0AHE3/54 exhibits a maximum reverse leakage current of 2000 μA at its 5.0 V stand-off voltage (VWM). This low leakage supports efficient standby operation in battery-powered and always-on automotive modules without excessive quiescent drain.
