Product details
Overview
5KP6.0A-E3/51 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 50 mA, 5000 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 485 A peak pulse current - deployed on DC power rails and MOSFET gate drivers in automotive and industrial power supplies.
For engineers reviewing the 5KP6.0A-E3/51 datasheet, 5KP6.0A-E3/51 pinout, 5KP6.0A-E3/51 application, or 5KP6.0A-E3/51 equivalent, key selection criteria include unidirectional polarity, P600 through-hole package compatibility, 175 °C max junction temperature, AEC-Q101 qualification, and verified clamping performance under 10/1000 µs transients.
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protector with avalanche breakdown behavior. Its glass-passivated P600 chip junction delivers low incremental surge resistance and sub-nanosecond response time, enabling effective suppression of inductive switching spikes and lightning-induced surges on 6 V nominal DC lines.
It is rated for 5000 W peak pulse power (10/1000 µs), 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and withstands 600 A non-repetitive forward surge current (8.3 ms half-sine). The device is RoHS-compliant (E3 suffix), JESD201 Class 1A whisker-tested, and UL 94 V-0 molded epoxy packaged.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 6.67 V / 7.37 V at 50 mA - ensures reliable avalanche initiation within tight tolerance band |
| VC @ IPPM | ≤10.3 V at 485 A - defines worst-case clamped voltage during 10/1000 µs surge |
| PPPM | 5000 W - peak transient energy handling capacity per JEDEC standard waveform |
| TJ max | +175 °C - enables operation in under-hood automotive and high-temp industrial environments |
| Polarity | Unidirectional - cathode-banded; blocks reverse current until breakdown, conducts forward like rectifier |
| IFSM | 600 A - surge current rating for 8.3 ms half-sine, critical for fuse-coordination in crowbar replacement |
Pinout & Package
5KP6.0A-E3/51 uses the axial-lead P600 package: molded epoxy body with matte tin-plated leads, 0.340–0.360 inch (8.6–9.1 mm) body diameter, 0.375 inch (9.5 mm) length, and color band denoting cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry / surge return path | Connected to ground or low-side rail; carries full surge current during clamping |
| Cathode (banded end) | Reverse-biased protection node | Connected to protected line (e.g., +6 V rail); initiates avalanche conduction when V > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control modules and body electronics |
| 5000 W peak pulse power (10/1000 µs) | Enables single-device protection against ISO 7637-2 Pulse 5a/b and IEC 61000-4-5 Level 4 surges |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes stress on downstream 6 V-rated ICs and MOSFETs during transient events |
| P600 glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial and automotive enclosures |
Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Output |
|---|---|
Use Scenario: Protecting 6 V battery-fed circuits in commercial vehicle ECUs from load dump and alternator ripple. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed between +6 V rail and chassis ground, responding within <1 ns to transients exceeding 6.67 V. Use Value: Prevents latch-up or gate oxide rupture in 6 V logic and CAN transceivers by limiting excursion to ≤10.3 V at 485 A. | Use Scenario: Safeguarding output stage of 6 V switching power supply driving solenoids and relays in factory automation. IC Role / Device Role / Timing Role: Crowbar-replacement surge absorber across output terminals, conducting only during overvoltage events. Use Value: Allows upstream fuse to clear without device failure, supporting maintenance-friendly resettable protection architecture. |
| MOSFET Gate Driver Protection | Telecom DC Feeder Line Protection |
Use Scenario: Shielding N-channel MOSFET gate-source terminals in 6 V gate-drive circuits from Miller-induced spikes. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to source, absorbing positive-going gate overvoltage while blocking negative swing. Use Value: Maintains safe VGS < ±20 V margin, preventing parasitic turn-on and short-circuit failure in high-side switches. | Use Scenario: Hardening 6 V bias feeders in outdoor telecom remote radio units exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary-level TVS on DC input before DC-DC converter, mounted directly at connector entry point. Use Value: Withstands repetitive 5 kV/500 A surges per IEC 61000-4-5, reducing need for multi-stage protection networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A | Lower PPPM (600 W), SMC package, 100 A IPPM, same VWM/VBR range | Surface-mount alternative for space-constrained PCBs; unsuitable for 5 kA-level surge duty | Select SMBJ6.0A only where board area is critical and surge threat level is ≤IEC 61000-4-5 Level 2 |
| 1.5KE6.8A | Same P600 package, higher VBR (7.14–7.89 V), lower PPPM (1500 W), 217 A IPPM | Limited to lower-energy transients; not AEC-Q101 qualified | Choose 1.5KE6.8A for cost-sensitive industrial applications lacking automotive qualification requirements |
Compared with SMBJ6.0A and 1.5KE6.8A, the 5KP6.0A-E3/51 uniquely combines 5000 W surge capability, AEC-Q101 qualification, and P600 robustness - making it the only option for automotive-grade 6 V rail protection requiring single-device Level 4 compliance.

FAQ
What is the clamping voltage of the 5KP6.0A-E3/51 under maximum surge conditions?
The 5KP6.0A-E3/51 clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 485 A (10/1000 µs waveform). This value is measured and guaranteed per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 5KP6.0A-E3/51 suitable for automotive applications?
Yes, the 5KP6.0A-E3/51 is AEC-Q101 qualified and explicitly rated for automotive use. Its P600 package, 175 °C max junction temperature, and robust surge performance make it appropriate for engine control units, body control modules, and other under-hood applications requiring certified transient protection.
Does the 5KP6.0A-E3/51 have bidirectional polarity?
No, the 5KP6.0A-E3/51 is unidirectional only. It features a cathode band and functions as a reverse-biased avalanche diode - conducting surge current only when the anode-to-cathode voltage exceeds the breakdown threshold. Bidirectional variants are not offered in the 5KP family.
What is the meaning of the "E3/51" suffix in 5KP6.0A-E3/51?
The "E3" denotes RoHS-compliant, commercial-grade construction meeting JESD201 Class 1A whisker resistance; "/51" specifies the packaging option - 51 indicates 500-piece bulk pack (as opposed to /54 for tape-and-reel). Both reflect Vishay's standardized ordering nomenclature for the P600 series.
Can the 5KP6.0A-E3/51 replace a 5KP6.0CA in a design?
No - the 5KP6.0A-E3/51 is unidirectional, whereas 5KP6.0CA is bidirectional. Substituting them would compromise protection on AC-coupled or dual-polarity signal lines. For bidirectional needs, select a designated CA-series part such as 5KP6.0CA-E3/51, which has symmetric breakdown in both directions.
