Product details
Overview
5KP24-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC power rails and signal lines. It features 24 V stand-off voltage (VWM), 26.7–29.5 V breakdown voltage (VBR) at 5.0 mA, 5000 W peak pulse power (10/1000 μs), clamping voltage of 38.9 V at 129 A, and operates from –55 °C to +175 °C - used in automotive power supply output protection and industrial sensor interface circuits.
For engineers reviewing the 5KP24-E3/73 datasheet, 5KP24-E3/73 pinout, 5KP24-E3/73 application, or 5KP24-E3/73 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant packaging details, and AEC-Q101 qualification status - all critical for overvoltage protection design validation and component selection in safety-critical systems.
Technical Context
The 5KP24-E3/73 employs a glass-passivated P600 junction optimized for fast response (<1 ns) to transient events such as inductive load switching and lightning-induced surges. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
It delivers 5000 W peak pulse power with 10/1000 μs waveform at 0.01% duty cycle, supported by low incremental surge resistance and excellent clamping ratio (VC/VBR ≈ 1.35). Thermal performance is defined by 8.0 W power dissipation on infinite heatsink at TL = 75 °C and full derating above TA = 25 °C per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 24.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping onset. |
| VBR (Breakdown Voltage) | 26.7–29.5 V at 5.0 mA - Confirmed avalanche initiation range; ensures reliable turn-on during transients without premature conduction. |
| VC (Clamping Voltage) | 38.9 V at IPPM = 129 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream device stress level. |
| PPPM (Peak Pulse Power) | 5000 W - Sustained energy absorption capability under standardized surge waveform; validates suitability for IEC 61000-4-5 Level 4. |
| IFSM (Surge Current) | 600 A (8.3 ms half-sine) - Withstands repetitive overcurrent events without bond-wire failure; supports fuse-coordinated protection schemes. |
| TJ max. | +175 °C - Enables operation in under-hood automotive environments and high-ambient industrial enclosures without thermal shutdown. |
| Polarity | Unidirectional - Blocks reverse current until VBR is exceeded; required for DC power rail protection with fixed bias. |

Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between 24 V rail and chassis ground to clamp surges before they reach LDOs and microcontrollers. Use Value: Withstands 5000 W pulses while limiting clamped voltage to 38.9 V - preserving 40 V-rated input stages of automotive PMICs and CAN FD controllers. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events in factory automation. IC Role / Device Role / Timing Role: TVS mounted at connector entry point to shunt fast transients before reaching op-amp front-end or ADC input. Use Value: Sub-1 ns response time and 38.9 V clamping prevent latch-up or damage to precision 24-bit sigma-delta ADCs operating at ±10 V full scale. |
| Telecom DC Power Feeds | Switched-Mode Power Supply Output Clamping |
Use Scenario: Safeguarding PoE-powered equipment (e.g., IP cameras) against induced surges on 48 V DC feed lines. IC Role / Device Role / Timing Role: Unidirectional TVS installed across secondary-side output capacitor to absorb line-to-ground transients. Use Value: 24 V VWM provides sufficient margin above nominal 48 V/2:1 tapped output; 5000 W rating handles multiple telecom surge standards simultaneously. |
Use Scenario: Replacing crowbar SCR circuits in 24 V SMPS outputs to simplify protection architecture. IC Role / Device Role / Timing Role: TVS connected directly across output terminals to conduct only during overvoltage, allowing fuse interruption without short-circuit latching. Use Value: 600 A IFSM rating permits sustained conduction long enough for 10 A fast-blow fuses to clear - enabling safe reset after fault. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range, bidirectional option available. | Targeted at board-level signal line protection rather than bulk power rail clamping. | Select when space-constrained layouts or lower-energy transients (IEC 61000-4-2) dominate; not suitable for ISO 7637-2 Pulse 5. |
| 1.5KE24A | Same P600 package, 1500 W PPPM, higher clamping voltage (43 V), lower cost, non-AEC-Q101. | Used in commercial/industrial power supplies where automotive qualification is unnecessary. | Choose for cost-sensitive non-automotive designs requiring basic 24 V rail protection without AEC-Q101 traceability. |
Compared with SMBJ24A and 1.5KE24A, the 5KP24-E3/73 delivers three times the surge power handling and automotive-grade reliability - making it the only choice among the three for under-hood ECU protection where 5000 W transients and 175 °C ambient operation are mandatory.

FAQ
What is the clamping voltage of the 5KP24-E3/73 under a 10/1000 μs surge?
The 5KP24-E3/73 has a maximum clamping voltage (VC) of 38.9 V at peak pulse current (IPPM) of 129 A, measured using the standard 10/1000 μs waveform. This value is guaranteed per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 40 V-rated downstream components.
Is the 5KP24-E3/73 qualified for automotive applications?
Yes, the 5KP24-E3/73 is AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number 88308, Revision 20-Nov-12). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD - validating its use in engine control units, body electronics, and ADAS modules where reliability under harsh conditions is mandatory.
What does the "E3/73" suffix indicate in 5KP24-E3/73?
The "E3" denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker testing; "/73" specifies the preferred packaging code - 73 indicates 800-piece tape-and-reel delivery in 13-inch diameter reels. This matches Vishay's ordering convention shown in the datasheet's "Ordering Information" section.
Can the 5KP24-E3/73 replace a 1.5KE24A in an existing design?
The 5KP24-E3/73 shares the same P600 package and VWM/VBR range as the 1.5KE24A but offers 3.3× higher peak pulse power (5000 W vs. 1500 W) and AEC-Q101 qualification. Physical drop-in replacement is possible, but thermal and layout validation is required due to higher energy dissipation - especially important in automotive or high-duty-cycle applications.
What is the maximum operating temperature for the 5KP24-E3/73?
The 5KP24-E3/73 has a specified operating junction and storage temperature range of –55 °C to +175 °C. Its 175 °C TJ max. rating allows direct mounting on PCBs adjacent to power MOSFETs or inlets exposed to under-hood ambient temperatures up to 125 °C, provided thermal derating per Figure 2 is observed.
