Product details
Overview
5KP5.0AHE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 5.0 V stand-off voltage (VWM), and 9.2 V clamping voltage (VC) at 543 A peak pulse current. It serves as primary overvoltage protection on DC power rails of automotive ECUs and industrial switching supplies.
For engineers reviewing the 5KP5.0AHE3/73 datasheet, 5KP5.0AHE3/73 pinout, 5KP5.0AHE3/73 application, or 5KP5.0AHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, unidirectional polarity with cathode band marking, and 5000 W surge capability - critical for automotive-grade power rail hardening and IEC 61000-4-5 compliance.
Technical Context
This TVS diode uses a glass-passivated P600 chip junction optimized for fast response (<1 ps) and low incremental surge resistance, enabling precise clamping during lightning-induced transients or inductive load switching events. Its breakdown voltage (VBR) is 6.4–7.0 V at 50 mA test current, ensuring reliable turn-on before downstream IC damage.
The device operates within -55 °C to +175 °C junction range and supports repetitive surge duty cycles up to 0.01 %, with thermal derating above 25 °C per Fig. 2. Its 3.5 V forward voltage at 100 A confirms robust conduction during bidirectional fault conditions when used with external rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage; sets minimum system rail margin before clamping activation |
| VBR @ IT=50 mA | 6.4–7.0 V - Breakdown threshold tolerance ensures consistent turn-on across production lots |
| VC @ IPPM=543 A | 9.2 V - Clamped voltage under 5000 W surge; defines maximum stress on protected ICs |
| PPPM | 5000 W - Peak pulse power rating with 10/1000 μs waveform; meets IEC 61000-4-5 Level 4 |
| IFSM | 600 A - Non-repetitive forward surge current (8.3 ms half-sine); supports crowbar-style fault clearing |
| TJ max | +175 °C - Enables under-hood automotive placement without thermal derating penalties |
| Polarity | Unidirectional - Cathode-band marked; suitable for DC rail protection only, not AC line applications |

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 peak power (600 W), SMC package, 9.6 V clamping at 65 A | Suitable for board-level ESD (IEC 61000-4-2), not for IEC 61000-4-5 line surges | Select when space-constrained layouts require surface-mount and surge energy is <100 J |
| 1.5KE5.0A | Same P600 package but lower peak power (1500 W), 12.7 V clamping at 118 A | Lacks AEC-Q101 qualification; limited to commercial-temperature industrial use | Choose for cost-sensitive non-automotive designs where 5000 W rating is unnecessary |
Compared with SMBJ5.0A and 1.5KE5.0A, the 5KP5.0AHE3/73 delivers 3.3× higher surge power handling and automotive-grade reliability, making it the sole option among the three qualified for under-hood deployment and high-energy line transients.

FAQ
What is the clamping voltage of the 5KP5.0AHE3/73 under maximum surge conditions?
The 5KP5.0AHE3/73 clamps to 9.2 V at its rated peak pulse current of 543 A (10/1000 μs waveform). This value is measured per JEDEC standards and guarantees that protected downstream circuitry sees no more than 9.2 V during a full 5000 W transient event, preserving 5 V logic integrity.
Is the 5KP5.0AHE3/73 suitable for automotive applications?
Yes, the 5KP5.0AHE3/73 is AEC-Q101 qualified and rated for -55 °C to +175 °C operation, making it suitable for engine control units, body control modules, and ADAS power domains. Its P600 package withstands mechanical shock and thermal cycling per automotive requirements.
How does the 5KP5.0AHE3/73 differ from standard 5.0 V Zener diodes?
Unlike general-purpose Zeners, the 5KP5.0AHE3/73 is optimized for transient suppression: it handles 5000 W surges (vs. <1 W for Zeners), exhibits sub-nanosecond response, and maintains stable clamping over 1000+ surge events. Its VWM = 5.0 V and VBR = 6.4–7.0 V provide precise margining absent in conventional Zener tolerances.
What is the meaning of the 'HE3' suffix in 5KP5.0AHE3/73?
The 'HE3' suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this grade from commercial 'E3' variants and confirms suitability for automotive and high-reliability industrial use.
Can the 5KP5.0AHE3/73 be used in AC line protection?
No - the 5KP5.0AHE3/73 is unidirectional and rated only for DC applications. Its cathode-band marking and lack of symmetrical breakdown make it unsuitable for AC line filtering or bidirectional surge scenarios; use a bidirectional TVS like 5KP5.0CA for such cases.
