Product details
Overview
5KP9.0AHE3_A/C from Vishay General Semiconductor is a unidirectional 5000 W transient voltage suppressor (TVS) diode in P600 package, with 9.0 V stand-off voltage, 10.0–11.1 V breakdown voltage at 5 mA, and 325 A peak pulse current (10/1000 μs). It protects MOSFETs and ICs in automotive power supplies against lightning-induced surges and inductive switching transients.
For engineers reviewing the 5KP9.0AHE3_A/C datasheet, 5KP9.0AHE3_A/C pinout, 5KP9.0AHE3_A/C application, or 5KP9.0AHE3_A/C equivalent, key selection criteria include clamping voltage (15.4 V), AEC-Q101 qualification, unidirectional polarity, P600 thermal performance, and 175 °C max junction temperature for under-hood automotive use.
Technical Context
This TVS diode uses a glass-passivated P600 chip junction optimized for high-energy transient suppression. Its low incremental surge resistance and fast response time enable effective clamping of 10/1000 μs surges up to 5000 W without degradation under repetitive 0.01 % duty cycle conditions.
Designed for crowbar-circuit replacement in switching power supply outputs, it sustains 500 A non-repetitive forward surge current (8.3 ms half-sine) and maintains stable clamping up to 175 °C junction temperature, with ±0.081 %/°C VBR temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum reverse operating voltage before conduction begins; sets system-level overvoltage trip threshold |
| VBR (min/max) | 10.0 V / 11.1 V at 5 mA - guaranteed breakdown range ensures consistent turn-on across production lots |
| VC @ IPPM | 15.4 V - clamping voltage during 325 A transient; limits downstream device stress below safe thresholds |
| PPPM | 5000 W - peak pulse power handling with 10/1000 μs waveform; supports high-energy surge standards like ISO 7637-2 |
| TJ max | +175 °C - enables under-hood placement in automotive ECUs without derating concerns |
| Polarity | Unidirectional - provides reverse-biased surge protection only; requires correct cathode orientation in PCB layout |
| AEC-Q101 | Qualified - validated for automotive reliability including temperature cycling, HTRB, and ESD per AEC standard |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; 9.5 mm body length; color band denotes cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or return path); defines unidirectional conduction direction |
| Cathode | Reverse-biased surge clamping node | Connected to protected line (e.g., 12 V rail); absorbs positive transients by avalanche breakdown |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Enables single-device protection against severe ISO 7637-2 Pulse 5a/b transients without parallel staging |
| AEC-Q101 qualification | Validates long-term reliability in automotive environments including thermal shock and humidity exposure |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes voltage overshoot during clamping-critical for safeguarding 12 V logic interfaces and gate drivers |
| P600 thermal mass | Supports 8.0 W steady-state dissipation on infinite heatsink at 75 °C lead temperature-reduces need for external heatsinking |
| 175 °C junction rating | Permits operation in engine compartment locations where ambient exceeds 125 °C |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS clamps positive surges on main power input before they reach PMICs and microcontrollers. Use Value: Clamps to 15.4 V at 325 A, preventing latch-up or gate oxide damage in downstream 16 V-rated components. | Use Scenario: Safeguarding programmable logic controllers (PLCs) powered from 24 V industrial supplies exposed to relay coil flyback. IC Role / Device Role / Timing Role: Standoff at 9.0 V allows normal operation; conducts within nanoseconds when transients exceed 10.0 V. Use Value: Withstands 500 A surge current (8.3 ms) without failure, enabling fuse coordination and system reset capability. |
| Switching Power Supply Output | Automotive Sensor Signal Line |
Use Scenario: Replacing crowbar circuits on secondary-side outputs of 12 V SMPS in ADAS domain controllers. IC Role / Device Role / Timing Role: Acts as self-resetting overvoltage clamp-absorbs energy then returns to high-impedance state. Use Value: Eliminates need for SCR-based crowbar + fuse replacement; reduces BOM count and improves MTBF. | Use Scenario: Protecting LIN bus transceivers and Hall-effect sensor inputs from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low capacitance (<100 pF at VWM) avoids signal integrity degradation on 20 kbps LIN lines. Use Value: Meets IEC 61000-4-2 Level 4 (15 kV air, 8 kV contact) while maintaining <1 ns response time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0AHE3_A/H | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range | Not suitable for ISO 7637-2 Pulse 5; limited to board-level ESD and lower-energy transients | Select when space-constrained and surge energy ≤600 W; verify thermal margin in continuous operation |
| 5KP9.0A-E3/54 | Same electrical specs and P600 package; differs only in packaging format (tape-and-reel vs. ammo pack) | No functional difference; identical AEC-Q101 qualification and performance | Choose based on assembly line feed requirements-not an electrical alternative |
Compared with 5KP9.0AHE3_A/C, SMBJ9.0AHE3_A/H offers footprint reduction but sacrifices 83 % peak power handling, while 5KP9.0A-E3/54 is a packaging variant-not a design alternative-requiring no schematic or layout change.

FAQ
What is the clamping voltage of the 5KP9.0AHE3_A/C under maximum surge conditions?
The 5KP9.0AHE3_A/C clamps to a maximum of 15.4 V when subjected to its rated peak pulse current of 325 A (10/1000 μs waveform). This value is measured at the device terminals and represents the upper limit of voltage seen by downstream circuitry during surge events, ensuring compatibility with 16 V-rated components.
Is the 5KP9.0AHE3_A/C qualified for automotive applications?
Yes, the 5KP9.0AHE3_A/C carries AEC-Q101 qualification, confirmed in Vishay's official documentation (Document Number 88308, Revision 16-Mar-2023). This includes testing for temperature cycling, highly accelerated life testing (HALT), and ESD robustness-making it suitable for under-hood and chassis-mounted automotive modules.
What does the "HE3" suffix indicate in 5KP9.0AHE3_A/C?
The "HE3" suffix in 5KP9.0AHE3_A/C indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. The "_A/C" denotes the packaging configuration: "C" stands for 13-inch paper tape and reel, base quantity 800 units, per Vishay's ordering nomenclature.
Can the 5KP9.0AHE3_A/C be used in bidirectional configurations?
No, the 5KP9.0AHE3_A/C is unidirectional only, as explicitly stated in the Vishay datasheet. It protects against positive transients on the cathode side and must be oriented with the banded end toward the protected line. For bidirectional protection, two devices in series opposition or a dedicated bidirectional TVS (e.g., 5KP9.0CA) would be required.
What is the maximum junction temperature rating for the 5KP9.0AHE3_A/C?
The 5KP9.0AHE3_A/C has a maximum junction temperature (TJ) rating of +175 °C, verified per JEDEC test conditions. This allows reliable operation in high-ambient environments such as engine control units, where sustained case temperatures may exceed 125 °C, provided thermal design meets the derating curve in Figure 2 of the datasheet.
