Product details
Overview
5KP6.5A-E3/51 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 5000 W peak pulse power (10/1000 μs), 7.22–7.98 V breakdown voltage at 50 mA, and clamps to ≤11.2 V at 446 A peak pulse current. Used in automotive power supplies and industrial sensor interfaces where robust surge immunity is required.
For engineers reviewing the 5KP6.5A-E3/51 datasheet, 5KP6.5A-E3/51 pinout, 5KP6.5A-E3/51 application, or 5KP6.5A-E3/51 equivalent, this page delivers verified electrical parameters, JEDEC-registered clamping behavior, AEC-Q101 qualification status, thermal derating curves, and RoHS-compliant packaging details - all critical for high-reliability board-level ESD and lightning surge protection design.
Technical Context
The 5KP6.5A-E3/51 operates as a unidirectional avalanche diode with glass-passivated P600 junction, optimized for fast response (<1 ns) to transients induced by inductive switching or lightning surges. Its 5000 W peak pulse rating is defined per 10/1000 μs waveform at 0.01% duty cycle, with clamping voltage tightly bounded at 11.2 V under 446 A stress.
Thermal performance is governed by junction-to-lead resistance and mounting surface area: power dissipation drops linearly above 25 °C ambient, reaching zero at 175 °C maximum junction temperature. The device meets JESD 22-B106 soldering requirements (275 °C, 10 s) and JESD 201 Class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.22 V / 7.98 V at 50 mA - defines guaranteed avalanche onset range for reliable turn-on during overvoltage events |
| VWM | 6.5 V - maximum continuous reverse operating voltage; ensures no conduction during normal DC rail operation |
| VC @ IPPM | ≤11.2 V at 446 A - clamping voltage limits downstream IC stress during worst-case surge conditions |
| PPPM | 5000 W (10/1000 μs) - enables protection against high-energy transients without crowbar circuitry |
| IFSM | 600 A (8.3 ms half-sine) - supports single-event surge survival without bond wire fusing |
| TJ max | 175 °C - allows operation in under-hood automotive environments and sealed industrial enclosures |
| Polarity | Unidirectional - cathode band marked; blocks reverse current until breakdown, conducts forward like standard diode |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; 0.375" (9.5 mm) body length; lead spacing matches industry-standard through-hole footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connects to lower-potential side of protected line (e.g., ground or return); carries full surge current during clamping |
| Cathode | Avalanche breakdown terminal | Marked with color band; connects to higher-potential side (e.g., +12 V rail); initiates clamping when VAK exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JESD47 |
| 5000 W peak pulse power | Eliminates need for external crowbar circuits in 12 V/24 V power supply outputs |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a/5a) |
| RoHS-compliant (E3 suffix) | Meets EU Directive 2011/65/EU; JESD 201 Class 1A whisker tested for long-term solder joint integrity |
| Fast response time | <1 ns turn-on enables protection of sensitive MOSFET gates and microcontroller I/O pins |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Primary shunt clamp on main power input, placed upstream of DC-DC converters and LDOs. Use Value: Clamps to ≤11.2 V during 446 A surges, preventing damage to downstream regulators rated for ≤16 V absolute max. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to PLC analog inputs in factory automation. IC Role / Device Role / Timing Role: Unidirectional TVS on signal line between sensor and isolation amplifier, referenced to local ground. Use Value: Limits induced lightning surges (IEC 61000-4-5 Level 3) to sub-12 V levels, preserving 24-bit ADC accuracy and avoiding latch-up. |
| Telecom DC Power Feeds | Consumer Power Adapter Outputs |
Use Scenario: Overvoltage suppression on -48 V telecom rectifier outputs exposed to field wiring faults and induced surges. IC Role / Device Role / Timing Role: Standoff-rated TVS across output terminals, sized for 5000 W pulse handling per GR-1089-CORE. Use Value: Withstands repetitive 10/1000 μs surges up to 0.01% duty cycle without degradation, enabling multi-year field deployment. | Use Scenario: Secondary-side surge protection on USB-C PD adapter 20 V output rails before USB-PD controller and port protection ICs. IC Role / Device Role / Timing Role: Final-stage clamping device after bulk capacitance, absorbing residual energy not filtered by X/Y caps and common-mode chokes. Use Value: Fast <1 ns response prevents voltage overshoot from propagating to Type-C CC logic and VCONN circuitry during hot-plug events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A | Lower peak pulse power (600 W), smaller SMB package, same VBR range (7.22–7.98 V) | Not suitable for load dump or high-energy lightning surges; limited to board-level ESD and low-energy transients | Select SMBJ6.5A only when space-constrained layouts and <1 kV/10/1000 μs threat levels apply |
| 1.5KE6.8A | Same P600 package, but lower peak pulse power (1500 W), higher VC (11.5 V @ 130 A), tighter VBR tolerance (5%) | Lacks AEC-Q101 qualification; not recommended for automotive under-hood use | Choose 1.5KE6.8A only for cost-sensitive industrial controls where AEC-Q101 is not mandated |
Compared with SMBJ6.5A and 1.5KE6.8A, the 5KP6.5A-E3/51 uniquely delivers 5000 W surge capacity in a through-hole P600 package with AEC-Q101 validation - making it the only option among the three qualified for automotive load dump and industrial 4 kV IEC 61000-4-5 compliance.

FAQ
What is the clamping voltage of the 5KP6.5A-E3/51 under maximum surge conditions?
The 5KP6.5A-E3/51 clamps to a maximum of 11.2 V when subjected to its rated peak pulse current of 446 A (10/1000 μs waveform). This value is measured per JEDEC test conditions and guarantees downstream circuit protection within safe voltage margins. The clamping voltage remains stable across temperature due to low dynamic impedance, and is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88308.
Is the 5KP6.5A-E3/51 suitable for automotive applications?
Yes, the 5KP6.5A-E3/51 is AEC-Q101 qualified, as explicitly stated in the Mechanical Data section and footnote (1) of the Vishay datasheet (document 88308). This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - confirming suitability for under-hood and chassis-mounted automotive electronics.
What does the "E3/51" suffix indicate in 5KP6.5A-E3/51?
The "E3" suffix denotes RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 1A whisker testing, while "/51" specifies the preferred packaging code: 500-piece tape-and-reel format on 7-inch diameter reels. This differs from /54 (800-piece reels) and confirms compatibility with standard SMT placement equipment when used in automated through-hole insertion processes.
How does the 5KP6.5A-E3/51 differ from the 5KP6.5CA variant?
The 5KP6.5A-E3/51 is unidirectional, whereas 5KP6.5CA is bidirectional - meaning the latter protects against surges of either polarity and has symmetrical VBR ratings. The 5KP6.5A-E3/51's unidirectional structure provides lower leakage and tighter VWM margin (6.5 V vs. 6.5 V standoff in both), but requires correct polarity installation. Bidirectional variants are used on AC lines or floating differential signals.
Can the 5KP6.5A-E3/51 be used in parallel for higher surge current handling?
No - paralleling multiple 5KP6.5A-E3/51 devices is not recommended due to mismatched dynamic impedance and avalanche turn-on thresholds, which cause current imbalance and potential thermal runaway. For higher surge ratings, select a single higher-rated device (e.g., 5KP7.0A or 5KP7.5A) or consult Vishay's application note AN949 for staged protection architectures using series inductance and coordinated clamping.
