Product details
Overview
P6KE120AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 120 V breakdown voltage (VBR = 114–126 V at 1 mA), 102 V stand-off voltage (VWM), 165 V maximum clamping voltage (VC) at 3.6 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability - deployed in engine control units and battery management systems.
For engineers reviewing the P6KE120AHE3/54 datasheet, P6KE120AHE3/54 pinout, P6KE120AHE3/54 application, or P6KE120AHE3/54 equivalent, this page delivers verified electrical parameters, DO-15 package mechanical data, clamping behavior under surge, thermal resistance (RθJL = 20 °C/W), and real-world automotive/industrial protection use cases - all confirmed from Vishay's official 88369 document revision 27-Sep-2021.
Technical Context
The P6KE120AHE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to ESD and lightning-induced transients. Its unidirectional polarity uses a cathode band marking, and it conducts only during reverse overvoltage events while blocking forward current up to 102 V.
It is rated for 100 A non-repetitive forward surge (8.3 ms half-sine), 5.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and operates across –55 °C to +175 °C junction temperature range - supporting under-hood automotive environments and industrial motor drives where thermal cycling and high-energy surges coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 114 V / 126 V at 1 mA - defines precise avalanche initiation threshold for predictable clamping onset |
| VWM | 102 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 165 V at 3.6 A - limits transient voltage seen by protected ICs during 10/1000 µs surge |
| PPPM | 600 W - peak surge energy absorption capability under standardized waveform |
| RθJL | 20 °C/W - enables accurate junction temperature estimation from lead temperature in PCB layout |
| TJ max. | +175 °C - supports operation in high-ambient under-hood or industrial power converter locations |

|---|---|
Use Scenario: Protects microcontroller GPIO and CAN transceiver power rails from load dump and alternator ripple in 12 V vehicle systems. IC Role / Device Role / Timing Role: Primary clamping device placed at board-level input filter stage to limit transient voltage before LDOs and logic ICs. Use Value: Clamps 12 V rail surges up to 165 V within 1 ns, preventing latch-up or gate oxide damage in 3.3 V/5 V logic devices. | Use Scenario: Shields 24 V digital input circuitry from field-wiring induced surges caused by relay coil de-energization or nearby motor switching. IC Role / Device Role / Timing Role: Standoff-rated TVS placed directly across input terminals to absorb >600 W surge energy without failure. Use Value: Maintains 102 V working voltage while clamping 3.6 A pulses to ≤165 V, ensuring input optocoupler and conditioning circuit survival. |
| Telecom Power Supply Front-End | Consumer Appliance Motor Drive Board |
Use Scenario: Guards AC/DC adapter secondary-side 48 V output against lightning-induced surges entering via Ethernet or PoE lines. IC Role / Device Role / Timing Role: Secondary-side transient suppressor located after bulk capacitor, upstream of DC-DC converters.

IC Role / Device Role / Timing Role: Localized protection element mounted near microcontroller pins to suppress fast-edge EMI coupling. Use Value: Responds in <1 ns to sub-microsecond spikes, holding clamped voltage below 165 V while dissipating 600 W peak energy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ120A | Same VBR range (114–126 V), but SMA package (surface-mount); lower PPPM = 400 W | Requires PCB rework for SMT layout; unsuitable for through-hole legacy designs | Select when board space is constrained and thermal management allows lower surge rating |
| 1.5KE120A | Higher PPPM = 1500 W, same DO-15 package and VBR, but not AEC-Q101 qualified | Acceptable for industrial/commercial use; lacks automotive qualification documentation and stress testing | Select for cost-sensitive non-automotive applications needing higher surge margin |
Compared with P6KE120AHE3/54, SMAJ120A trades package compatibility and surge rating for miniaturization, while 1.5KE120A offers greater energy handling without automotive qualification - making P6KE120AHE3/54 the optimal choice where AEC-Q101 compliance and through-hole assembly are mandatory.

FAQ
What is the clamping voltage of P6KE120AHE3/54 at its rated peak pulse current?
The P6KE120AHE3/54 has a maximum clamping voltage (VC) of 165 V at its rated peak pulse current (IPPM) of 3.6 A under the standard 10/1000 µs waveform. This value is measured per Vishay Document 88369 and ensures protected downstream components experience no more than 165 V during worst-case surge events - a key parameter for validating safe operating margins in 12 V or 24 V systems.
Is P6KE120AHE3/54 suitable for automotive applications?
Yes, P6KE120AHE3/54 is AEC-Q101 qualified, as explicitly stated in Vishay's datasheet revision 27-Sep-2021. The HE3 suffix denotes RoHS-compliant, AEC-Q101-qualified construction, including stress testing for high-temperature reverse bias, unbiased high-temperature storage, and temperature cycling - making P6KE120AHE3/54 appropriate for engine control modules, body control units, and other automotive electronics requiring certified reliability.
What does the "HE3/54" suffix mean in P6KE120AHE3/54?
The "HE3" suffix in P6KE120AHE3/54 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "54" refers to the preferred package code for 13-inch paper tape and reel packaging with 4000 units per reel. This full ordering code ensures traceable, automotive-grade delivery format - distinct from commercial-grade "E3/54" variants lacking AEC-Q101 validation.
How does P6KE120AHE3/54 differ from bidirectional P6KE120CA?
P6KE120AHE3/54 is unidirectional with cathode band marking and specified forward voltage (VF = 5.0 V at 50 A), while P6KE120CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The "A" suffix denotes unidirectional; "CA" denotes bidirectional. P6KE120AHE3/54 is used where DC polarity is fixed (e.g., 12 V supply rails), whereas P6KE120CA suits AC-coupled or dual-polarity signal lines.
What is the thermal resistance from junction to lead for P6KE120AHE3/54?
The typical thermal resistance from junction to lead (RθJL) for P6KE120AHE3/54 is 20 °C/W, per Vishay Document 88369. This value enables accurate thermal modeling when the device is soldered to copper traces acting as heat paths - critical for maintaining junction temperature below 175 °C during repetitive surge events or elevated ambient conditions in automotive under-hood applications.
