Product details
Overview
5KP110AHE3_A/C from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on power rails and signal lines. It features 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR) at 5 mA, 177 V maximum clamping voltage (VC) at 28.2 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 5KP110AHE3_A/C datasheet, 5KP110AHE3_A/C pinout, 5KP110AHE3_A/C application, or 5KP110AHE3_A/C equivalent, key selection criteria include clamping performance under 10/1000 μs surges, AEC-Q101 qualification for automotive use, unidirectional polarity, P600 package thermal handling, and compatibility with 8.3 ms half-sine surge withstand per IEC 61000-4-5.
Technical Context
This TVS diode operates as a voltage-clamped crowbar element during overvoltage transients, leveraging a glass-passivated P600 junction to achieve low incremental surge resistance and sub-nanosecond response time. Its unidirectional structure enables DC-biased rail protection without reverse conduction leakage concerns above VWM.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient, supporting operation in engine bay and industrial control environments. It meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 2 whisker resistance (HE3 suffix), confirming robustness for automated assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for protected circuitry. |
| VBR (min/max) | 122 V / 135 V at 5 mA - Confirmed breakdown threshold range; ensures predictable turn-on across production lot and temperature. |
| VC @ IPPM | 177 V at 28.2 A - Clamped voltage during 10/1000 μs surge; determines maximum stress imposed on downstream components. |
| PPPM | 5000 W - Peak pulse power handling with 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 surge immunity testing. |
| TJ max. | 175 °C - Maximum junction temperature; enables reliable operation in under-hood automotive and high-ambient industrial settings. |
| Polarity | Unidirectional - Cathode-marked device; suitable for DC power rail protection where reverse conduction must be blocked. |
| AEC-Q101 | Qualified - Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; 9.5 mm body length; lead spacing 9.1 mm; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during positive transients on cathode side. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 12 V rail); conducts when voltage exceeds VBR, shunting surge energy to ground. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Enables single-device protection against severe lightning-induced surges (IEC 61000-4-5) without parallel staging. |
| AEC-Q101 qualification | Validates reliability for automotive power modules, body control units, and ADAS sensor power inputs. |
| 177 V clamping at 28.2 A | Limits voltage overshoot below 180 V during 10/1000 μs transients - critical for safeguarding 150 V-rated MOSFETs and gate drivers. |
| P600 thermal mass | Supports 8.0 W steady-state dissipation on infinite heatsink at TL = 75 °C, enabling passive thermal management in space-constrained designs. |
| Low incremental surge resistance | Minimizes VC rise under high di/dt events, improving clamping precision and reducing stress on downstream silicon. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Output |
|---|---|
|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and alternator transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed between power input and ground, activated within nanoseconds of overvoltage onset. Use Value: Withstands 5000 W surges while clamping to ≤177 V, preventing latch-up or destruction of microcontrollers and CAN transceivers. |
Use Scenario: Safeguarding output stage of 48 V telecom rectifiers against induced lightning surges and switching spikes. IC Role / Device Role / Timing Role: Crowbar-style transient suppressor across output terminals, diverting energy before upstream fuses open. Use Value: Enables resettable protection architecture - system resumes operation after transient clears, unlike sacrificial fuses. |
| Sensor Interface Surge Suppression | MOSFET Gate Driver Input Protection |
|
Use Scenario: Shielding analog front-end inputs of automotive pressure/temperature sensors connected to long harnesses. IC Role / Device Role / Timing Role: Unidirectional TVS on sensor supply line (VDD), referenced to local ground plane. Use Value: Low leakage (<2 μA at 110 V) avoids signal offset; fast response preserves integrity of millivolt-level sensor outputs. |
Use Scenario: Preventing gate oxide damage in high-side N-channel MOSFET drivers exposed to inductive kickback. IC Role / Device Role / Timing Role: Clamping diode from driver output to ground, limiting gate-source voltage excursion during turn-off. Use Value: 177 V clamping ensures gate voltage stays within ±20 V absolute max rating of common logic-level MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110AHE3/A | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range, AEC-Q101 qualified. | Targeted at board-level signal line protection; insufficient for bulk power rail surge handling. | Select when space-constrained layout and lower-energy transients (e.g., ESD, contact discharge) dominate. |
| 1.5KE110A | Same VWM/VBR/VC specs, 5000 W rating, DO-201 package, not AEC-Q101 qualified. | Lacks automotive qualification; thermal resistance higher than P600; no HE3 whisker rating. | Acceptable for industrial/commercial power supplies where AEC-Q101 is not mandated and manual assembly is used. |
Compared with SMBJ110AHE3/A and 1.5KE110A, the 5KP110AHE3_A/C uniquely combines AEC-Q101 qualification, P600 thermal mass for high-repetition surges, and full 5000 W capability - making it the only choice for automotive power rail protection requiring both reliability and energy-handling headroom.

FAQ
What is the clamping voltage of the 5KP110AHE3_A/C under a standard 10/1000 μs surge?
The 5KP110AHE3_A/C clamps to a maximum of 177 V when subjected to its rated peak pulse current of 28.2 A with a 10/1000 μs waveform. This value is measured per JEDEC standards and represents the upper limit of voltage seen by protected circuitry during such an event - critical for ensuring downstream components remain within their absolute maximum ratings.
Is the 5KP110AHE3_A/C suitable for automotive applications?
Yes, the 5KP110AHE3_A/C is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including HE3 suffix (JESD 201 Class 2 whisker resistance), P600 thermal robustness, and 175 °C junction rating - meets requirements for engine control modules, body electronics, and ADAS power domains per ISO 16750 and ISO 7637-2.
What does the "HE3_A/C" suffix mean in 5KP110AHE3_A/C?
The "HE3" denotes RoHS-compliant, AEC-Q101-qualified construction with JESD 201 Class 2 whisker resistance; "A/C" specifies the revision code and packaging format - 13-inch paper tape and reel, 800 units per reel, with P600 package and cathode band marking per Vishay's ordering convention.
How does the 5KP110AHE3_A/C differ from the 1.5KE110A in practical design?
The 5KP110AHE3_A/C uses a P600 package offering superior thermal dissipation (8.0 W vs. ~3.0 W for DO-201) and is AEC-Q101 qualified, whereas the 1.5KE110A is DO-201 packaged and lacks automotive qualification. Both share identical VWM/VBR/VC specs, but only the 5KP110AHE3_A/C supports sustained surge duty cycles in automotive environments.
Can the 5KP110AHE3_A/C be used in bidirectional configurations?
No, the 5KP110AHE3_A/C is unidirectional only, with cathode marked by a band. For bidirectional transient suppression, Vishay offers separate part numbers like 5KP110CA; using two unidirectional devices back-to-back is not recommended due to mismatched VBR tolerances and increased leakage risk.
