Product details
Overview
P6KE82AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of sensitive electronics. It features a 70.1 V standoff voltage (VWM), 77.9–86.1 V breakdown voltage (VBR) at 1 mA, 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the P6KE82AHE3/54 datasheet, P6KE82AHE3/54 pinout, P6KE82AHE3/54 application, or P6KE82AHE3/54 equivalent, key selection criteria include clamping performance under 5.3 A surge, thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and DO-15 lead-form compatibility with legacy PCB footprints.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to transient overvoltages induced by inductive switching or ESD events. Its unidirectional polarity uses a cathode band marking and exhibits low incremental surge resistance, enabling effective voltage clamping without significant forward conduction during normal operation.
The P6KE82AHE3/54 is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; its 5.0 W steady-state power dissipation on infinite heatsink (TL = 75 °C) supports reliable operation in thermally constrained industrial environments.

|---|---|
|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and inductive kickback in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp transients before they reach the input stage of the sensor interface IC. Use Value: Limits clamped voltage to 113 V during 5.3 A surge, preventing latch-up or gate oxide damage in 3.3 V/5 V interface ICs. |
Use Scenario: Shielding digital input channels on programmable logic controllers from field-wiring surges caused by relay coil de-energization or lightning-induced coupling. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input terminals, coordinated with upstream fuse and series impedance. Use Value: Delivers 600 W pulse handling with <1 ns response, ensuring transient energy is shunted before reaching optocoupler or microcontroller input pins. |
| Consumer Power Adapter Input | Telecom Line Interface Protection |
|
Use Scenario: Secondary-side surge suppression on 12 V output rails of AC/DC adapters used in set-top boxes and network routers. IC Role / Device Role / Timing Role: Standoff-rated TVS across regulated output to absorb cross-regulation spikes and rectifier reverse recovery energy. Use Value: 70.1 V VWM provides 15 % margin above nominal 12 V output, avoiding leakage while enabling robust 113 V clamping during fault conditions. |
Use Scenario: Front-end protection of Ethernet PHY or RS-485 transceivers connected to outdoor cabling exposed to ESD and induced surges. IC Role / Device Role / Timing Role: First-line defense on differential pairs, paired with common-mode chokes and GDTs in multi-stage protection schemes. Use Value: Low RθJL (20 °C/W) allows direct mounting to ground plane, sustaining repeated 10/1000 μs pulses without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ80A | DO-214AA package; 80 V VWM, 125 V VC @ 4.8 A; 600 W rating; surface-mount | Requires SMT rework; higher clamping voltage reduces margin for 5 V logic interfaces | Select when board space is constrained and reflow assembly is preferred over through-hole |
| 1.5KE82A | Same DO-15 package; 70.1 V VWM, 113 V VC @ 5.3 A; identical electrical specs but commercial-grade (non-AEC-Q101) | Lacks automotive qualification; unsuitable for under-hood or safety-critical systems | Acceptable for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated |
Compared with SMBJ80A and 1.5KE82A, P6KE82AHE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and 113 V clamping at 5.3 A - making it the preferred choice for automotive and industrial designs requiring proven reliability and legacy footprint support.

FAQ
What is the clamping voltage of P6KE82AHE3/54 and how is it measured?
The P6KE82AHE3/54 has a maximum clamping voltage (VC) of 113 V, measured at 5.3 A peak pulse current using a standardized 10/1000 μs waveform per Figure 1 in Vishay Document 88369. This value represents the upper limit of voltage seen by protected circuitry during worst-case surge events and is guaranteed across temperature and production lots.
Is P6KE82AHE3/54 suitable for automotive applications?
Yes, P6KE82AHE3/54 is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision dated 27-Sep-2021. The HE3 suffix explicitly denotes AEC-Q101 qualification, covering tests including temperature cycling, high-temperature reverse bias, and ESD robustness - making P6KE82AHE3/54 appropriate for engine control units, body electronics, and ADAS sensor interfaces.
What does the "HE3/54" suffix mean in P6KE82AHE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery with 4000 units per reel. This ordering code ensures traceable, automotive-grade material with verified lead finish and packaging integrity for P6KE82AHE3/54.
How does P6KE82AHE3/54 compare to P6KE82A-E3/54?
P6KE82AHE3/54 and P6KE82A-E3/54 share identical electrical specifications and DO-15 packaging, but differ in qualification: P6KE82AHE3/54 is AEC-Q101 qualified (HE3), whereas P6KE82A-E3/54 is commercial grade (E3). Both meet RoHS, but only P6KE82AHE3/54 is validated for automotive reliability requirements - critical for safety-relevant systems.
What is the thermal resistance of P6KE82AHE3/54 and why does it matter?
P6KE82AHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, per Vishay's Thermal Characteristics table. This low value enables efficient heat transfer from the silicon junction to PCB copper pours or chassis mounts, allowing sustained operation at elevated ambient temperatures - essential for under-hood automotive use and enclosed industrial enclosures where airflow is limited.
