Product details
Overview
5KP120AHE3_A/C from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 120 V stand-off voltage (VWM), and 193 V clamping voltage (VC) at 25.9 A peak pulse current - deployed in automotive power supply outputs and industrial sensor signal lines.
For engineers reviewing the 5KP120AHE3_A/C datasheet, 5KP120AHE3_A/C pinout, 5KP120AHE3_A/C application, or 5KP120AHE3_A/C equivalent, key selection criteria include clamping performance under 10/1000 μs transients, AEC-Q101 qualification for automotive use, unidirectional polarity, and P600 package thermal handling per JESD 22-B106 soldering spec.
Technical Context
This TVS diode uses a glass passivated chip junction in a P600 molded epoxy case rated UL 94 V-0, delivering low incremental surge resistance and sub-nanosecond response to voltage transients. It operates across -55 °C to +175 °C junction temperature range and supports repetitive surge duty cycle up to 0.01 %.
Designed for crowbar circuit replacement in switching power supplies, it withstands 500 A non-repetitive forward surge (8.3 ms half-sine) while maintaining 3.5 V forward voltage at 100 A - enabling fuse/breaker coordination without device failure during overvoltage events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 120 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 133 V / 147 V at 5 mA - breakdown threshold range defining turn-on consistency |
| VC @ IPPM | 193 V at 25.9 A - clamped voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 5000 W - peak transient energy absorption capability per JEDEC standard waveform |
| IFSM | 500 A - surge current handling for 8.3 ms half-sine, supporting breaker/fuse coordination |
| TJ max | +175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| Polarity | Unidirectional - cathode marked by color band; blocks reverse current until breakdown |
Pinout & Package
Package: P600 - axial-leaded, molded epoxy body with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating and AEC-Q101 qualification (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to system ground or low-side return; conducts during positive surge on cathode side |
| Cathode | Protected line connection | Connected to protected line (e.g., 12 V rail); clamps transients above VWM to VC level |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Enables single-device protection against lightning-induced surges (IEC 61000-4-5 Level 4) on 12 V/24 V rails |
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements including HTGB, HTRB, and TCT |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), improving IC-level ESD robustness |
| P600 package thermal mass | Supports 8.0 W steady-state dissipation at TL = 75 °C, allowing direct PCB mounting without heatsink in moderate-duty cycles |
| Color-banded cathode marking | Ensures correct polarity orientation during manual or automated assembly, preventing reverse-bias failure |
Applications
| Automotive Power Supply Protection | Industrial Sensor Signal Line Guarding |
|---|---|

Use Value: Absorbs 5000 W transients per IEC 61000-4-5, reducing need for multi-stage protection and lowering BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ120A-E3/52 | Lower PPPM (600 W), smaller SMB package, same VWM (120 V), higher VC (199 V) | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when space-constrained layouts preclude P600 and surge energy remains ≤600 W |
| 1.5KE120A | Same VWM (120 V) and VC (193 V), but lower PPPM (1500 W), DO-201 package, no AEC-Q101 qualification | Lacks automotive qualification and thermal robustness for under-hood deployment | Choose only for cost-sensitive, non-automotive applications with verified <1500 W surge exposure |
Compared with SMBJ120A-E3/52 and 1.5KE120A, the 5KP120AHE3_A/C delivers 3.3× and 3.3× higher peak pulse power respectively, maintains AEC-Q101 compliance, and provides superior thermal margin in P600 - making it the sole choice for automotive load-dump and industrial high-energy surge scenarios.

FAQ
What is the clamping voltage of the 5KP120AHE3_A/C under a 10/1000 μs surge?
The 5KP120AHE3_A/C clamps to a maximum of 193 V when subjected to its rated peak pulse current of 25.9 A using the standardized 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting for downstream components such as DC-DC converters and microcontrollers in automotive and industrial systems.
Is the 5KP120AHE3_A/C qualified for automotive applications?
Yes, the 5KP120AHE3_A/C carries the HE3 suffix indicating full AEC-Q101 qualification. It has passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), making it suitable for under-hood and powertrain applications where reliability under thermal and electrical stress is critical.
What does the "A/C" in 5KP120AHE3_A/C signify?
The "A/C" in 5KP120AHE3_A/C denotes the preferred packaging code per Vishay's ordering nomenclature: "C" indicates 13-inch diameter paper tape and reel packaging with a base quantity of 800 units. The "A" is a revision identifier for the manufacturing lot, consistent with Vishay's internal change control protocol for the HE3 variant.
Can the 5KP120AHE3_A/C replace a crowbar circuit?
Yes, the 5KP120AHE3_A/C was explicitly designed to replace traditional SCR-based crowbar circuits in switching power supplies. Its 5000 W peak pulse power and 500 A surge current rating allow it to absorb fault energy long enough for fuses or breakers to interrupt - enabling system reset without device replacement, unlike sacrificial crowbars.
What is the maximum operating temperature for the 5KP120AHE3_A/C junction?
The 5KP120AHE3_A/C has a maximum junction temperature (TJ max) of +175 °C, validated per JEDEC standards. This enables reliable operation in high-ambient environments such as automotive engine compartments or industrial motor drive enclosures, provided PCB copper area and airflow meet Vishay's P600 thermal derating guidelines.
