Product details
Overview
P6KE7.5ARL 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 600 W peak pulse power (1 ms), 6.4 V working peak reverse voltage (VRWM), 11.3 V clamping voltage at 53 A peak pulse current (VC @ IPP), and <1 ns response time.
For engineers reviewing the P6KE7.5ARL datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, real-world protection use cases, validated alternatives, and supply-chain-ready availability details - all grounded in ON Semiconductor's official P6KE6.8A Series documentation (Rev. 10, Oct. 2009).
Technical Context
The P6KE7.5ARL operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 7.13–7.88 V breakdown range (VBR @ IT = 10 mA). Its clamping action limits transient-induced voltage to ≤11.3 V at 53 A, enabling robust protection of downstream ICs without sacrificing signal integrity.
It exhibits low leakage (<500 nA @ VRWM = 6.4 V), a temperature coefficient of 0.061 %/°C for VBR stability, and UL 497B recognition for isolated loop circuit protection - confirming suitability for safety-critical industrial and medical equipment interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W @ 1 ms - sustains single high-energy surges common in AC line or ESD events without failure |
| Working Peak Reverse Voltage | 6.4 V - sets maximum continuous DC/peak operating voltage before clamping initiates |
| Clamping Voltage | 11.3 V @ 53 A IPP - defines worst-case voltage seen by protected circuit during surge |
| Breakdown Voltage | 7.13–7.88 V @ 10 mA - precise avalanche threshold ensuring predictable turn-on behavior |
| Leakage Current | <500 nA @ 6.4 V - negligible standby power loss and minimal impact on high-impedance circuits |
| Response Time | <1 ns - fast enough to suppress ESD and lightning-induced transients before damage occurs |
| Temperature Coefficient | 0.061 %/°C - ensures stable VBR across −55°C to +150°C operating range |
Pinout & Package

| Pb-Free Option Available | P6KE7.5ARLG variant - supports RoHS-compliant manufacturing without performance trade-offs |
Applications
| Industrial Power Supply Protection | Medical Equipment Input Stage |
|---|---|
Use Scenario: 24 V DC input rail in programmable logic controller (PLC) power module exposed to load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp transients before they reach DC-DC converter ICs. Use Value: Limits voltage excursion to ≤11.3 V during 53 A surge, preventing latch-up or gate oxide damage in downstream regulators. | Use Scenario: Patient-connected sensor interface in ECG monitor requiring galvanic isolation and surge immunity per IEC 60601-1. IC Role / Device Role / Timing Role: Primary overvoltage protector on isolated analog front-end supply line, certified to UL 497B for loop protection. Use Value: Maintains signal integrity while meeting medical safety standards - no degradation in common-mode rejection due to low leakage (<500 nA). |
| Telecom Line Interface | Office Equipment Surge Defense |
Use Scenario: RS-485 data line in networked point-of-sale terminal subjected to induced lightning surges on long cable runs. IC Role / Device Role / Timing Role: Fast-response clamping device placed across differential pair, referenced to local ground plane. Use Value: Sub-1 ns response prevents data corruption; 600 W rating handles multi-kV transients without thermal runaway. | Use Scenario: 12 V auxiliary rail in multifunction printer exposed to ESD from user interaction and power-line noise. IC Role / Device Role / Timing Role: Board-level TVS on power entry, protecting motor drivers and microcontroller I/O pins. Use Value: Class 3 ESD rating (>16 kV HBM) eliminates field failures from static discharge; axial lead allows through-hole mounting for mechanical reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Surface-mount SMB package; 7.0 V VRWM; 12.5 V VC @ 48.2 A; same 600 W rating | Requires PCB re-layout for SMD placement; better high-frequency decoupling due to lower parasitic inductance | Select when space-constrained designs or automated assembly demand SMD packaging |
| P6KE7.5A | Identical electrical specs; axial-leaded but supplied in bulk (1000/unit box), not tape-and-reel | No functional difference; differs only in packaging format and reel compatibility | Select when manual assembly or low-volume prototyping favors bulk packaging |
Compared with P6KE7.5ARL, SMBJ7.0A offers superior high-frequency transient suppression in compact layouts but lacks UL 497B certification, while P6KE7.5A delivers identical protection performance with simpler logistics for non-automated production.

FAQ
What is the clamping voltage of the P6KE7.5ARL and how is it measured?
The P6KE7.5ARL has a maximum clamping voltage (VC) of 11.3 V, measured at a peak pulse current (IPP) of 53 A with a 1 ms exponential waveform per Figure 4 in the datasheet. This value represents the highest voltage the device allows across its terminals during a standardized surge event - critical for ensuring protected circuits remain below their absolute maximum ratings. The P6KE7.5ARL maintains this clamping performance across its full operating temperature range.
Does the P6KE7.5ARL meet UL safety standards?
Yes, the P6KE7.5ARL is UL Recognized under standard UL 497B (File #E210057, QVGQ2 category) for isolated loop circuit protection. This certification confirms successful completion of Strike Voltage Breakdown, Endurance Conditioning, Dielectric Withstand, and Discharge testing - making it suitable for safety-critical applications like medical and telecom isolation barriers. The P6KE7.5ARL shares this qualification with the full P6KE6.8A–P6KE200A series.
What is the working peak reverse voltage (VRWM) of the P6KE7.5ARL and why does it matter?
The P6KE7.5ARL has a VRWM of 6.4 V - the maximum continuous reverse voltage it can withstand without entering breakdown. This parameter determines the highest normal operating voltage of the protected line; selecting a VRWM ≥ system operating voltage prevents false triggering while ensuring reliable clamping during overvoltage events. For a 5 V rail, the P6KE7.5ARL provides margin; for 12 V systems, a higher-voltage variant would be required.
How does the P6KE7.5ARL handle thermal stress during repeated surges?
The P6KE7.5ARL is rated for 600 W peak pulse power at TL ≤ 25°C, with derating above that temperature per Figure 2. Its junction-to-lead thermal resistance is 20 °C/W, enabling effective heat dissipation into PCB copper or external heatsinking. For repetitive surges, average power must stay within steady-state limits (5.0 W at TL ≤ 25°C, derated above 50°C), and duty cycle must follow Figure 6 guidance - the P6KE7.5ARL itself does not specify repetitive surge endurance beyond these thermal constraints.
Is the P6KE7.5ARL RoHS compliant and what is its lead finish?
Yes, the P6KE7.5ARL is RoHS compliant. Its "RL" suffix denotes tape-and-reel packaging, and the device uses a Pb-free lead finish compatible with standard SnPb and lead-free soldering processes. Maximum lead temperature is specified at 260°C for 10 seconds at 1/16″ from the case - consistent with IPC-J-STD-020 moisture sensitivity level (MSL) requirements for through-hole components. The P6KE7.5ARL's corrosion-resistant finish ensures long-term solderability and reliability.
