Product details
Overview
P6KE82ARL from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic-40 package, designed to protect sensitive electronics against high-energy transients. It features 82 V breakdown voltage (VBR), 113 V clamping voltage (VC) at 5.3 A peak pulse current (IPP), 600 W peak power dissipation, and <1 ns response time - ideal for safeguarding power supplies and industrial control interfaces.
For engineers reviewing the P6KE82ARL datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (70.1 V), low leakage (<5 µA @ VRWM), UL 497B recognition for isolated loop protection, and Pb-free tape-and-reel packaging (4000 units/reel).
Technical Context
The P6KE82ARL operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 77.9–86.1 V breakdown range (VBR min/max @ 1 mA). Its clamping action limits transient-induced voltage to ≤113 V at 5.3 A IPP, with thermal resistance of 20 °C/W (junction-to-lead) enabling reliable surge handling under lead-temperature-limited conditions.
It complies with UL 497B for isolated loop circuit protection and meets Class 3 ESD rating (>16 kV HBM). The device exhibits a temperature coefficient of 0.105 %/°C for VBR, ensuring predictable voltage drift across −55 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 77.9–86.1 V @ 1 mA - defines precise conduction onset threshold for overvoltage events |
| Clamping Voltage (VC) | 113 V @ 5.3 A IPP - maximum voltage seen by protected circuit during 600 W transient |
| Working Peak Reverse Voltage (VRWM) | 70.1 V - maximum continuous reverse voltage before leakage exceeds 5 µA |
| Peak Pulse Power (PPK) | 600 W @ 1 ms - single-pulse energy absorption capability per Figure 4 waveform |
| Response Time | <1 ns - enables suppression before fast-rising transients damage downstream ICs |
| ESD Rating (HBM) | Class 3 (>16 kV) - qualifies for high-static-environment applications like medical equipment |

Applications
| Industrial Power Supply Protection | Telecom Line Interface |
|---|---|
Use Scenario: DC input stage of programmable logic controller (PLC) power module exposed to load-dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +24 V rail and chassis ground to clamp positive-going surges. Use Value: Limits transient voltage to ≤113 V, preventing damage to upstream rectifier and downstream DC-DC controller ICs. | Use Scenario: RS-485 data line interface in building automation system connected to long outdoor cabling. IC Role / Device Role / Timing Role: Line-side TVS on differential pair to absorb lightning-induced common-mode surges. Use Value: Fast <1 ns response prevents data corruption during sub-microsecond transients; UL 497B supports isolation barrier integrity. |
| Medical Equipment Input Stage | Process Control Sensor Interface |
Use Scenario: AC/DC adapter input for portable ultrasound unit subject to hospital-grade ESD and power-line disturbances. IC Role / Device Role / Timing Role: Primary-level TVS on AC input bridge output to suppress differential-mode surges. Use Value: Class 3 HBM rating (>16 kV) ensures immunity to operator-handling ESD; low leakage avoids bias current errors in precision analog front-end. | Use Scenario: 4–20 mA current loop transmitter in chemical plant with high EMI and ground potential differences. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; unidirectional P6KE82ARL used on supply rail to protect loop-powered sensor IC. Use Value: 70.1 V VRWM matches typical 48 V loop supply headroom; 150 °C rating sustains operation near hot process piping. |
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 | Surface-mount SMB package; 80 V VRWM; 100 W peak power; 100 V VC @ 3.5 A | Lower power rating and smaller footprint - suited for space-constrained PCBs but not direct replacement for 600 W demands | Select SMBJ80A only when board layout prohibits axial leads and surge energy is ≤100 W |
| 1.5KE82A | Same axial package; identical VRWM/VBR/VC specs; 1500 W peak power; higher IPP (18.4 A) | Higher surge capacity - appropriate where repeated high-energy transients occur, e.g., motor drive feedback lines | Choose 1.5KE82A when legacy 600 W margin is insufficient and mechanical compatibility is retained |
Compared with SMBJ80A, P6KE82ARL delivers 6× higher surge power in axial form; versus 1.5KE82A, it offers tighter cost/performance balance for standard industrial surge profiles without over-engineering.

FAQ
What is the clamping voltage of the P6KE82ARL and how does it protect downstream components?
The P6KE82ARL has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current. This means that during a transient event, the device limits the voltage across protected circuitry to no more than 113 V - well below destructive thresholds of most 100 V-rated capacitors and MOSFETs. Its fast <1 ns response ensures clamping occurs before voltage overshoot damages sensitive ICs, making P6KE82ARL effective for safeguarding power rails and interface lines.
Is the P6KE82ARL RoHS-compliant and what packaging options are available?
Yes, the P6KE82ARL is RoHS-compliant and offered in Pb-free packaging. The "RLG" suffix (e.g., P6KE82ARLG) explicitly denotes the Pb-free version supplied in tape-and-reel format (4000 units/reel). Standard P6KE82ARL uses leaded terminations but remains compliant with RoHS exemption 7a for high-melting-temperature solder alloys. Both variants share identical electrical specifications and Surmetic-40 axial package dimensions.
How does the P6KE82ARL differ from bidirectional TVS diodes like P6KE82CA?
The P6KE82ARL is unidirectional and functions only during negative transients relative to its cathode, making it suitable for DC rail protection where polarity is fixed. In contrast, P6KE82CA is bidirectional and clamps both positive and negative excursions - required for AC lines or floating signal paths. Using P6KE82ARL on an AC circuit would leave half the waveform unprotected; always match device polarity to system grounding architecture when selecting P6KE82ARL.
Can the P6KE82ARL be used in parallel to increase surge current handling?
No - P6KE82ARL should not be paralleled due to manufacturing tolerances in breakdown voltage (±5% VBR spread). Mismatched devices will not share current evenly, causing one diode to conduct first and fail prematurely. For higher surge ratings, select a single higher-power device such as 1.5KE82A (1500 W), which maintains identical VRWM/VBR specs while providing proven current-sharing capability within its rated pulse envelope.
What is the thermal derating behavior of the P6KE82ARL above 25°C ambient temperature?
The P6KE82ARL's steady-state power dissipation (PD) is rated at 5.0 W up to 50°C lead temperature, then derated linearly at 50 mW/°C beyond that point - reaching zero at 150°C. Its junction-to-lead thermal resistance is 20 °C/W, meaning a 5 W dissipation causes 100°C rise above lead temperature. For reliable operation, maintain lead temperature ≤125°C using adequate copper pour or heatsinking, especially in enclosed industrial enclosures where ambient may exceed 70°C.
