Product details
Overview
5KP5.0A-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 a 5.0 V stand-off voltage (VWM), 6.4–7.0 V breakdown voltage (VBR) at 50 mA, 5000 W peak pulse power (10/1000 µs), clamping voltage of 9.2 V at 543 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP5.0A-E3/73 datasheet, 5KP5.0A-E3/73 pinout, 5KP5.0A-E3/73 application, or 5KP5.0A-E3/73 equivalent, this device is selected for robust overvoltage protection in switching power supply outputs, MOSFET gate drivers, and automotive sensor interfaces where fast response (<1 ns), low clamping ratio, and high surge current handling are critical design requirements.
Technical Context
The 5KP5.0A-E3/73 uses a glass-passivated P600 junction to achieve stable avalanche breakdown with low incremental surge resistance and excellent clamping linearity under 10/1000 µs transients. Its unidirectional polarity supports DC-biased protection paths without reverse leakage concerns above VWM.
It operates across –55 °C to +175 °C junction temperature range, derates linearly above 25 °C ambient, and sustains 600 A non-repetitive forward surge (8.3 ms half-sine) - enabling use in crowbar-replacement circuits where controlled short-circuit behavior allows fuse/breaker coordination before catastrophic failure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 5.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 6.4–7.0 V at 50 mA - Tight 5% tolerance ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 9.2 V at 543 A - Limits protected circuit voltage during 5 kW surge, enabling safe operation of 12 V logic and power stages |
| PPPM (Peak Pulse Power) | 5000 W (10/1000 µs) - Withstands high-energy lightning-induced surges per IEC 61000-4-5 Level 4 |
| ID (Reverse Leakage) | 2000 µA max at VWM - Low leakage preserves efficiency in always-on power rail protection |
| TJ max | +175 °C - Supports under-hood automotive environments and high-temperature industrial enclosures |
| Polarity | Unidirectional - Optimized for DC power line protection with cathode band marking |

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), smaller SMB package, same VWM/VBR range | Suitable for board-level signal line protection but insufficient for load dump or high-power rail clamping | Select when space-constrained and surge energy is ≤600 W (e.g., USB, CAN, I²C lines) |
| 1.5KE5.0A | Same P600 package and 5000 W rating, but higher clamping voltage (10.5 V) and no AEC-Q101 qualification | Lacks automotive qualification; used in industrial/commercial power supplies only | Choose for cost-sensitive non-automotive designs where 1.3 V higher clamping is acceptable |
Compared with SMBJ5.0A and 1.5KE5.0A, the 5KP5.0A-E3/73 uniquely combines automotive qualification, lowest clamping voltage (9.2 V), and P600 ruggedness - making it the preferred choice for safety-critical 12 V rail protection where energy absorption and reliability are non-negotiable.

FAQ
What is the clamping voltage of the 5KP5.0A-E3/73 under maximum surge conditions?
The 5KP5.0A-E3/73 has a maximum clamping voltage (VC) of 9.2 V at 543 A peak pulse current (IPPM), measured with a 10/1000 µs waveform. This value ensures protected circuits remain within safe operating limits during high-energy transients such as ISO 7637-2 load dump events. The low VC/VBR ratio (~1.35) reflects superior clamping efficiency compared to standard TVS diodes.
Is the 5KP5.0A-E3/73 suitable for automotive applications?
Yes, the 5KP5.0A-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, P600 package, and –55 °C to +175 °C operating range - meets stress test requirements for powertrain and body electronics. The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, essential for under-hood reliability.
How does the 5KP5.0A-E3/73 differ from the 1.5KE5.0A?
The 5KP5.0A-E3/73 and 1.5KE5.0A share the P600 package and 5000 W rating, but the 5KP5.0A-E3/73 offers lower clamping voltage (9.2 V vs. 10.5 V), tighter VBR tolerance (5% vs. 10%), and AEC-Q101 qualification. These differences make the 5KP5.0A-E3/73 preferable for automotive applications where clamping precision and qualification are mandatory.
What is the reverse leakage current of the 5KP5.0A-E3/73 at its stand-off voltage?
The 5KP5.0A-E3/73 exhibits a maximum reverse leakage current (ID) of 2000 µA at its 5.0 V stand-off voltage (VWM), measured at 25 °C. This low leakage ensures minimal power loss in always-on protection configurations and avoids unintended biasing of downstream circuitry - critical for battery-powered and low-quiescent-current systems.
Can the 5KP5.0A-E3/73 be used in bidirectional protection schemes?
No, the 5KP5.0A-E3/73 is unidirectional only, with cathode marked by a color band. It conducts only during reverse overvoltage events relative to its anode-to-cathode orientation. For AC or bidirectional signal line protection, a dedicated bidirectional TVS (e.g., 5KP5.0CA) or back-to-back configuration would be required - the 5KP5.0A-E3/73 must be installed with correct polarity to function as intended.
