Product details
Overview
5KP15-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR) at 50 mA, 24.4 V clamping voltage (VC) at 205 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 5KP15-E3/73 datasheet, 5KP15-E3/73 pinout, 5KP15-E3/73 application, or 5KP15-E3/73 equivalent, key selection criteria include unidirectional polarity, 15 V stand-off rating, 205 A surge capability, thermal derating above 25 °C, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS diode operates as a voltage-clamped crowbar element during transients, leveraging a glass-passivated P600 junction to achieve low incremental surge resistance and sub-nanosecond response time. Its 10/1000 μs waveform rating reflects standardized surge immunity testing per REA and ANSI/IEEE C62.35, with clamping performance validated at 205 A peak pulse current.
The device is rated for continuous power dissipation of 8.0 W on an infinite heatsink at 75 °C lead temperature, with operating junction temperature spanning –55 °C to +175 °C. It meets JESD 201 Class 1A whisker resistance and UL 94 V-0 flammability requirements, and its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.0 V - maximum reverse working voltage before conduction; defines safe operating margin for 12 V nominal DC rails. |
| VBR (min/max) | 16.7 V / 18.5 V at 50 mA - guaranteed breakdown threshold range; ensures consistent turn-on across production lots. |
| VC @ IPPM | 24.4 V at 205 A - clamping voltage under full-rated surge; limits downstream voltage stress during ESD or load dump. |
| PPPM | 5000 W - peak pulse power handling with 10/1000 μs waveform; supports high-energy transients without failure. |
| IFSM | 500 A - non-repetitive forward surge current rating (8.3 ms half-sine); enables robust fault-current withstand in crowbar applications. |
| TJ max | +175 °C - maximum junction temperature; allows operation in under-hood automotive environments and high-ambient industrial settings. |
| Leakage @ VWM | 2.0 μA - ultra-low reverse leakage at stand-off voltage; minimizes standby power loss in battery-powered systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ15A | Same 15 V VWM, but 400 W PPPM (SMA package); lower surge capacity and thermal mass. | Restricted to low-energy transients (IEC 61000-4-2/4-4); unsuitable for load dump or high-current inductive switching. | Select only for space-constrained PCBs where 5KP15-E3/73's P600 footprint is prohibitive and surge energy is <500 W. |
| Vishay 5KP15AHE3/73 | Identical electrical specs and P600 package; differs only in AEC-Q101 qualification and JESD 201 Class 2 whisker rating (vs. Class 1A). | Required for automotive OEM designs requiring formal qualification evidence; otherwise electrically interchangeable. | Choose 5KP15AHE3/73 when AEC-Q101 documentation and extended whisker resistance are mandatory; otherwise 5KP15-E3/73 suffices for commercial/industrial use. |
Compared with SMAJ15A, 5KP15-E3/73 delivers 12.5× higher surge power handling and superior thermal stability; versus 5KP15AHE3/73, it offers identical protection performance at lower cost and qualification overhead for non-automotive applications.

FAQ
What is the clamping voltage of the 5KP15-E3/73 under full-rated surge current?
The 5KP15-E3/73 has a maximum clamping voltage (VC) of 24.4 V when subjected to its rated peak pulse current of 205 A with a 10/1000 μs waveform. This value is measured per JEDEC-standard test conditions and guarantees that downstream circuitry sees no more than 24.4 V during worst-case transient events, making it suitable for protecting 24 V system components with 30 V absolute maximum ratings.
Is the 5KP15-E3/73 RoHS compliant and halogen-free?
Yes, the 5KP15-E3/73 is RoHS-compliant per Directive 2011/65/EU and conforms to JEDEC JS709A halogen-free standards. The "E3" suffix explicitly denotes RoHS-compliant commercial-grade construction, with matte tin-plated leads and UL 94 V-0 epoxy encapsulation - verified in Vishay's Material Category Policy documentation (Doc. #99912).
Can the 5KP15-E3/73 be used in automotive applications?
The 5KP15-E3/73 shares identical die, P600 package, and electrical characteristics with the AEC-Q101-qualified 5KP15AHE3/73. While 5KP15-E3/73 itself is commercial-grade, its construction and thermal performance (TJ max = +175 °C) meet automotive under-hood environmental demands; however, formal AEC-Q101 certification requires the HE3 variant for OEM compliance.
What is the reverse leakage current of the 5KP15-E3/73 at its stand-off voltage?
At its 15.0 V stand-off voltage (VWM), the 5KP15-E3/73 exhibits a maximum reverse leakage current (ID) of 2.0 μA at 25 °C. This ultra-low leakage ensures minimal power drain in always-on systems such as automotive body controllers or battery-backed industrial sensors, preserving energy efficiency without compromising protection readiness.
How does the 5KP15-E3/73 differ from the 5KP15A variant?
The 5KP15-E3/73 and 5KP15A refer to the same base device - "5KP15A" is the generic part number family designation, while "5KP15-E3/73" specifies the RoHS-compliant commercial-grade version in 13″ tape-and-reel packaging (73 = 800 pcs/reel). No electrical or mechanical differences exist between them; the suffixes denote packaging, plating, and compliance attributes only.
