Product details

Overview

5KP10A-E3/51 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 10.0 V stand-off voltage (V_WM), and 17.0 V clamping voltage (V_C) at 294 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.

For engineers reviewing the 5KP10A-E3/51 datasheet, 5KP10A-E3/51 pinout, 5KP10A-E3/51 application, or 5KP10A-E3/51 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and RoHS-compliant matte tin-plated leads per J-STD-002.

Technical Context

This TVS diode operates as a voltage-clamping device triggered by overvoltage transients-such as those from inductive load switching or lightning-induced surges-and conducts excess energy to ground while limiting downstream voltage to ≤17.0 V. Its glass-passivated P600 junction enables fast response time and stable breakdown behavior under repetitive 0.01% duty cycle conditions.

The 5KP10A-E3/51 features a fixed unidirectional polarity (cathode marked by color band), requires no biasing circuitry, and functions without control signals. Its 8.0 W steady-state power dissipation on infinite heatsink and 600 A IFSM rating support robust fault handling in DC power rail protection applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	10.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC blocking level.
V_BR min/max	11.1 V / 12.3 V - Breakdown voltage range at 5.0 mA test current; ensures predictable turn-on threshold.
V_C @ I_PPM	17.0 V - Clamped voltage at 294 A peak pulse current (10/1000 μs); limits stress on protected ICs.
P_PPM	5000 W - Peak pulse power handling capability; sustains high-energy transients without failure.
I_FSM	600 A - Non-repetitive forward surge current (8.3 ms half-sine); supports crowbar-like fault clearing.
T_J max	175 °C - Maximum junction temperature; enables operation in under-hood automotive environments.
Polarity	Unidirectional - Cathode-anode configuration; used where reverse-bias surge protection is required only.

Pinout & Package

Package: P600 molded epoxy case with glass-passivated chip junction; UL 94 V-0 rated; matte tin-plated leads solderable per J-STD-002; cathode denoted by color band.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry during forward conduction or surge clamping	Connected to protected circuit's ground or low-side return path; forms clamping loop with cathode.
Cathode	Current exit during clamping; marked by color band	Connected to protected line (e.g., 12 V rail); voltage rise above V_WM triggers avalanche conduction to anode.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock per JESD22.
5000 W peak pulse power	Handles high-energy transients (e.g., ISO 7637-2 Pulse 5a) without degradation across ≥1000 cycles.
Low incremental surge resistance	Minimizes V_C overshoot during fast-rising transients, improving clamping precision for sensitive logic.
RoHS-compliant E3 suffix	Meets JESD201 Class 1A whisker test; suitable for lead-free reflow and long-term storage in humid environments.
Fast response time	Sub-nanosecond avalanche turn-on ensures protection before transient reaches vulnerable downstream components.

Applications

Automotive Power Rail Protection	Industrial DC Power Supply Output
Use Scenario: Protecting 12 V battery-fed ECUs against load dump transients (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed between power rail and chassis ground; activates within nanoseconds of overvoltage onset.

Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) in engine bay harnesses from coupled EMI and ESD. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on signal line referenced to local ground; cathode tied to signal, anode to ground. Use Value: 17.0 V clamping prevents latch-up in op-amps and ADC inputs while maintaining signal integrity up to 1 MHz.	Use Scenario: Preventing gate oxide rupture in high-side N-channel MOSFETs driven by PWM controllers in motor drives. IC Role / Device Role / Timing Role: Clamp placed between gate and source; suppresses Miller-induced voltage spikes during fast switching transitions. Use Value: Fast response and low V_C limit gate-source voltage to safe levels (<20 V), avoiding destructive avalanche in the MOSFET.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ10A	Lower peak pulse power (600 W), smaller SMB package, same V_WM = 10 V	Not suitable for load dump; limited to board-level ESD and low-energy transients	Select when space-constrained and surge energy <500 W; not a drop-in replacement for 5KP10A-E3/51.
1.5KE10A	Same P600 package and 5000 W rating, but higher V_C = 18.2 V at 275 A, non-AEC-Q101	Lacks automotive qualification; higher clamping increases risk to 3.3 V/5 V logic interfaces	Acceptable for industrial power supplies where AEC-Q101 is not mandated and 1.2 V higher clamping is tolerable.

Compared with SMBJ10A and 1.5KE10A, the 5KP10A-E3/51 delivers superior automotive-grade reliability, lower clamping voltage, and verified performance under high-duty-cycle surge conditions-making it optimal for safety-critical 12 V rail protection where thermal stability and transient repeatability are essential.

FAQ

What is the clamping voltage of the 5KP10A-E3/51 under maximum surge conditions?

The 5KP10A-E3/51 clamps to 17.0 V at its rated peak pulse current of 294 A (10/1000 μs waveform). This value is guaranteed per JEDEC-registered test conditions and represents the maximum voltage seen by protected circuitry during a full-power transient event. The low clamping ratio (V_C/V_BR ≈ 1.45) reflects optimized junction design for minimal overshoot.

Is the 5KP10A-E3/51 suitable for automotive applications?

Yes, the 5KP10A-E3/51 is AEC-Q101 qualified and explicitly rated for automotive use-including under-hood environments up to 175 °C junction temperature. Its P600 package, matte tin plating, and 0.01% duty cycle capability meet ISO 16750-2 load dump and ISO 7637-2 pulse immunity requirements when properly mounted on adequate copper area.

Does the 5KP10A-E3/51 have bidirectional polarity?

No, the 5KP10A-E3/51 is unidirectional only, with cathode indicated by a color band. It conducts during positive transients on the cathode side relative to anode (i.e., protects against overvoltage on a positive rail). For AC or bipolar protection, a separate bidirectional part such as 5KP10CA must be selected.

What is the maximum steady-state power dissipation for the 5KP10A-E3/51?

The 5KP10A-E3/51 has a DC power dissipation rating of 8.0 W when mounted on an infinite heatsink at lead temperature (T_L) = 75 °C. In real-world PCB layouts, derating is required based on copper area and ambient temperature; typical practical dissipation ranges from 1.5 W to 4.0 W depending on thermal design.

How does the 5KP10A-E3/51 compare to standard Zener diodes in surge protection?

Unlike general-purpose Zeners, the 5KP10A-E3/51 is optimized for transient suppression-not regulation-with 5000 W peak pulse capability, lower dynamic impedance, and faster response. Its glass-passivated P600 junction handles repetitive surges without parameter drift, whereas standard Zeners lack pulse power ratings and degrade under similar stress.
