Product details
Overview
5KP5.0A-E3/51 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for primary overvoltage protection in 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), 543 A peak pulse current (IPPM), and clamps to ≤9.2 V at rated surge. It is used in automotive power supply inputs and industrial sensor interfaces where high-energy transients must be safely shunted without device failure.
For engineers reviewing the 5KP5.0A-E3/51 datasheet, 5KP5.0A-E3/51 pinout, 5KP5.0A-E3/51 application, or 5KP5.0A-E3/51 equivalent, this page delivers verified electrical parameters, P600 package dimensions, AEC-Q101 qualification status, clamping performance under JEDEC-standard 10/1000 μs surges, and direct alternatives with documented voltage and power trade-offs.
Technical Context
The 5KP5.0A-E3/51 operates as a silicon avalanche diode with glass-passivated P600 junction, optimized for single-pulse transient suppression rather than repetitive clamping. Its 175 °C maximum junction temperature and 8.0 W steady-state power dissipation support operation in thermally constrained environments when mounted on adequate copper area.
It exhibits 0.057 %/°C temperature coefficient of VBR and 2000 μA maximum reverse leakage at 5.0 V, confirming stable low-leakage behavior near its stand-off threshold. The device is rated for 600 A non-repetitive forward surge (8.3 ms half-sine) and meets JESD 22-B106 solderability standards up to 275 °C for 10 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse voltage before significant leakage; defines safe operating DC rail margin. |
| VBR (min/max) | 6.4 V / 7.0 V at 50 mA - Avalanche onset range; ensures reliable triggering above nominal supply. |
| VC @ IPPM | ≤9.2 V at 543 A - Clamped voltage during 10/1000 μs surge; limits downstream IC stress to sub-10 V. |
| PPPM | 5000 W - Peak transient energy handling per JEDEC 10/1000 μs waveform; supports high-energy load dump events. |
| IFSM | 600 A - Non-repetitive forward surge rating (8.3 ms); enables crowbar-style fault clearing without bond-wire fusing. |
| TJ max. | 175 °C - Maximum junction temperature; allows operation in under-hood automotive or industrial enclosures. |
| Polarity | Unidirectional - Cathode-banded configuration; protects against positive-going transients only. |
Pinout & Package
5KP5.0A-E3/51 uses the axial-lead P600 package: molded epoxy body (UL 94 V-0), matte tin-plated leads, cathode indicated by color band. Leads are solderable per J-STD-002 and JESD 22-B102; whisker-tested to JESD 201 Class 1A (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end opposite) | Transient current sink path | Connected to protected line; conducts surge current to ground when clamping. |
| Cathode (banded end) | Reference node / ground return | Typically tied to system ground; establishes polarity-specific clamping direction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD47. |
| 5000 W peak pulse power (10/1000 μs) | Handles ISO 7637-2 Pulse 5a load-dump surges in 12 V vehicle systems without degradation. |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes overvoltage overshoot during fast transients, reducing risk to downstream 5 V logic. |
| 0.057 %/°C VBR tempco | Ensures predictable breakdown shift across -55 °C to +175 °C ambient, critical for engine bay use. |
| P600 mechanical robustness | Withstands 275 °C solder dip (10 s); compatible with wave and selective soldering in high-volume production. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: 12 V battery feed to engine control unit (ECU) exposed to ISO 7637-2 load dump transients up to 120 V. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converter input. Use Value: Limits transient voltage to ≤9.2 V, preventing damage to 40 V-rated input MOSFETs and enabling fuse coordination. |
Use Scenario: Analog output line (0–5 V) from pressure sensor in factory automation PLC module. IC Role / Device Role / Timing Role: Fast-response surge limiter on signal path between sensor and ADC input. Use Value: Clamps ESD and inductive switching spikes within 1 ns, preserving 12-bit measurement accuracy. |
| Switching Power Supply Output Crowbar | Telecom DC Feeder Protection |
Use Scenario: 5 V/30 A output of telecom-grade AC-DC brick subjected to sustained overvoltage faults. IC Role / Device Role / Timing Role: Sacrificial crowbar element that shorts output to trigger OVP shutdown. Use Value: Withstands 600 A surge (8.3 ms) while maintaining low VF (3.5 V @ 100 A), ensuring reliable breaker tripping. |
Use Scenario: -48 V DC feeder line in central office equipment exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS on negative rail to suppress positive transients relative to ground. Use Value: Delivers 5000 W clamping at -48 V system level with <2000 μA leakage, minimizing standby power loss. |
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, 100 A IPPM, same VWM/VBR range. | Not suitable for load dump; limited to board-level ESD and low-energy switching noise. | Select when space-constrained and surge energy ≤600 W; verify thermal pad area for 8.0 W PD. |
| 1.5KE5.0A | Same P600 package, 1500 W PPPM, 227 A IPPM, identical VWM/VBR but higher VC (10.5 V). | Insufficient for ISO 7637-2 Pulse 5a; acceptable for IEC 61000-4-5 Level 3. | Choose if cost-sensitive and full 5000 W headroom not required; confirm clamping margin vs. downstream ratings. |
Compared with SMBJ5.0A and 1.5KE5.0A, the 5KP5.0A-E3/51 provides 3.3× and 3.3× higher peak pulse power respectively, enabling robust protection against automotive load dump and industrial power-line surges where lower-rated devices would fail catastrophically.

FAQ
What is the clamping voltage of the 5KP5.0A-E3/51 under maximum rated surge current?
The 5KP5.0A-E3/51 clamps to a maximum of 9.2 V when subjected to its rated peak pulse current of 543 A (10/1000 μs waveform). This value is measured per JEDEC standard test conditions and guarantees downstream circuit protection below 10 V during worst-case transients. The clamping voltage is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88308.
Is the 5KP5.0A-E3/51 suitable for automotive applications?
Yes, the 5KP5.0A-E3/51 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, robust P600 package, and 5000 W peak pulse power make it appropriate for protecting ECUs, body control modules, and ADAS power supplies against ISO 7637-2 load dump events. The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance.
What does the "-E3/51" suffix indicate in 5KP5.0A-E3/51?
The "-E3" denotes RoHS-compliant, commercial-grade packaging with JESD 201 Class 1A whisker resistance; "/51" specifies the preferred package code per Vishay's ordering matrix, corresponding to bulk packaging (not tape-and-reel). This differs from /54 (800-unit tape-and-reel) and confirms the part is supplied in industry-standard bulk format suitable for manual or selective soldering processes.
How does the 5KP5.0A-E3/51 differ from bidirectional TVS diodes?
The 5KP5.0A-E3/51 is unidirectional and protects only against positive transients on the anode-to-cathode path. Unlike bidirectional variants (e.g., 5KP5.0CA), it cannot suppress negative-going surges. Its design targets DC power rails where polarity is fixed, offering lower leakage (<2000 μA at 5.0 V) and tighter VBR tolerance versus bidirectional equivalents with dual-junction structures.
Can the 5KP5.0A-E3/51 replace a 1.5KE5.0A in an existing design?
Direct replacement is not recommended without layout and thermal review. While both use P600 packages and share VWM/VBR, the 5KP5.0A-E3/51 delivers 5000 W PPPM versus 1500 W for the 1.5KE5.0A - requiring larger copper pour for heat dissipation. Also, its lower clamping voltage (9.2 V vs. 10.5 V) may alter OVP timing; verify compatibility with downstream overvoltage thresholds before substitution.
