Product details
Overview
5KP15A-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal paths. It features a 15.0 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR) at 5.0 mA, 24.4 V clamping voltage (VC) at 205 A peak pulse current, and 5000 W peak pulse power capability with 10/1000 μs waveform - deployed to safeguard MOSFETs and ICs against inductive switching transients in automotive power supplies.
For engineers reviewing the 5KP15A-E3/73 datasheet, 5KP15A-E3/73 pinout, 5KP15A-E3/73 application, or 5KP15A-E3/73 equivalent, this part is evaluated for robust overvoltage clamping in 12 V–24 V automotive subsystems, industrial motor drives, and telecom power rails where AEC-Q101 qualification, low incremental surge resistance, and fast response time (<1 ns) are critical selection criteria.
Technical Context
This TVS diode uses a P600 glass-passivated chip junction housed in a molded epoxy case rated UL 94 V-0. Its unidirectional polarity enables integration into DC-biased circuits without reverse conduction during normal operation, while its 175 °C maximum junction temperature supports under-hood automotive deployment.
The device delivers 24.4 V clamping at 205 A (10/1000 μs), with <2.0 μA reverse leakage at 15.0 V and a 0.094 %/°C VBR temperature coefficient - ensuring stable clamping performance across wide thermal ranges without external biasing or thermal compensation circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 15.0 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below clamping threshold in 12 V systems. |
| VBR (Breakdown Voltage) | 16.7–18.5 V at 5.0 mA - Confirmed avalanche initiation range; ensures reliable turn-on prior to system damage thresholds. |
| VC (Clamping Voltage) | 24.4 V at 205 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; limits stress on downstream 30 V-rated MOSFETs. |
| PPPM (Peak Pulse Power) | 5000 W - Sustains 10/1000 μs surges per JEDEC standards; exceeds ISO 7637-2 Pulse 5a requirements for 24 V vehicle systems. |
| IFSM (Surge Current) | 600 A (8.3 ms half-sine) - Withstands repetitive load-dump events without degradation; validated per AEC-Q101 stress testing. |
| TJ max. | 175 °C - Enables placement near heat-generating components (e.g., DC/DC converters) without derating penalties in engine-control units. |
| Polarity | Unidirectional - Blocks reverse current during normal operation; eliminates need for series blocking diodes in DC rail protection. |
Pinout & Package
Package: P600 - Axial-leaded, molded epoxy body (9.5 mm length × 5.4 mm diameter), UL 94 V-0 rated, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Cathode terminal | Connected to system ground or low-side reference; defines unidirectional clamping direction from power rail to GND. |
| Cathode (non-banded end) | Anode terminal | Connected to protected line (e.g., battery feed); conducts surge current to ground when VLINE exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock per JESD47. |
| 5000 W peak pulse power (10/1000 μs) | Handles ISO 16750-2 load dump surges up to 35 V/100 ms without failure in 24 V commercial vehicle ECUs. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., relay coil de-energization), reducing risk of latch-up in microcontrollers. |
| Fast response time (<1 ns) | Activates before most semiconductor junctions enter avalanche, preventing cumulative degradation in repeated surge events. |
| RoHS-compliant, whisker-tested (JESD 201 Class 1A) | Ensures long-term solder joint integrity in high-vibration environments such as powertrain control modules. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive DC Bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Lower PPPM (600 W), smaller SMB package (3.5 mm × 4.6 mm), same VWM/VBR range. | Not AEC-Q101 qualified; suitable for consumer-grade PCBs with space constraints but insufficient for automotive load dump. | Select only for cost-sensitive, non-automotive applications with <1 kW surge exposure. |
| 1.5KE15A | Same P600 package and 5000 W rating, but higher clamping voltage (25.1 V) and no AEC-Q101 qualification. | Lacks automotive reliability validation; used in industrial controls where extended temperature cycling is not required. | Acceptable for legacy industrial designs where AEC-Q101 is not mandated and 0.7 V higher clamping is tolerable. |
Compared with SMBJ15A and 1.5KE15A, the 5KP15A-E3/73 uniquely combines AEC-Q101 qualification, 24.4 V clamping, and 5000 W surge capacity in the P600 form factor - making it the only option among the three qualified for under-hood automotive deployment with strict voltage margin requirements.

FAQ
What is the clamping voltage of the 5KP15A-E3/73 under a 10/1000 μs surge?
The 5KP15A-E3/73 has a maximum clamping voltage (VC) of 24.4 V at 205 A peak pulse current with a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that protected circuitry sees no more than 24.4 V during standardized surge events - critical for compatibility with 30 V-rated power MOSFETs and gate drivers in automotive applications.
Is the 5KP15A-E3/73 suitable for automotive under-hood use?
Yes, the 5KP15A-E3/73 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C junction temperature. Its P600 package, glass-passivated junction, and validated performance under temperature cycling, humidity bias, and mechanical shock make it suitable for engine control units, transmission control modules, and other under-hood automotive electronics.
How does the 5KP15A-E3/73 differ from the 1.5KE15A in practical design?
The 5KP15A-E3/73 offers identical P600 packaging and 5000 W peak pulse power but improves upon the 1.5KE15A with lower clamping voltage (24.4 V vs. 25.1 V), AEC-Q101 qualification, and tighter VBR tolerance (16.7–18.5 V vs. broader 16.7–20.2 V). These differences directly impact system-level surge margin and automotive compliance - the 5KP15A-E3/73 is the preferred choice where reliability and specification headroom are mandatory.
What is the reverse leakage current of the 5KP15A-E3/73 at its stand-off voltage?
At its 15.0 V stand-off voltage (VWM) and TA = 25 °C, the 5KP15A-E3/73 exhibits a maximum reverse leakage current (ID) of 2.0 μA. This low leakage ensures minimal standby power loss in always-on automotive modules and prevents unintended biasing of downstream analog sensing circuits.
Can the 5KP15A-E3/73 replace crowbar circuits in power supply designs?
Yes - per Vishay's application notes, the 5KP15A-E3/73 was explicitly designed to replace crowbar circuits on switching power supply outputs. It withstands high peak currents long enough to allow fuses or breakers to open, enabling system reset without component replacement - unlike crowbars that require manual intervention after activation.
