Product details
Overview
P6KE75ARL from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic-40 package, designed for parallel clamping of high-energy transients. It features 75 V breakdown voltage (VBR = 71.3–78.8 V @ IT = 1 A), 103 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPP), and 600 W peak pulse power rating per 1 ms waveform - deployed in industrial power supplies and communication interface protection.
For engineers reviewing the P6KE75ARL datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (VRWM = 64.1 V), low leakage (<5 µA @ VRWM), sub-1 ns response time, UL 497B recognition for isolated loop circuits, and Pb-free tape-and-reel packaging (4000 pcs/reel).
Technical Context
The P6KE75ARL operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its specified VBR range. Its clamping action limits transient overvoltage to ≤103 V under 5.8 A 1 ms pulses, maintaining circuit integrity during ESD or lightning-induced surges.
Thermal design relies on junction-to-lead resistance (RJL = 20 °C/W) and steady-state power dissipation (PD = 5.0 W @ TL ≤ 25°C), derated linearly above 50°C. It meets Class 3 ESD immunity (>16 kV HBM) and complies with UL 497B for isolated loop protection in telecom and process control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Surface-mount SMB package; same VRWM (64.1 V), slightly higher VC (121 V @ 4.9 A) | Requires PCB re-layout; better suited for high-density designs where axial leads are impractical | Select SMBJ75A when space-constrained layouts or automated assembly without axial lead handling is required. |
| 1.5KE75A | Same axial package but higher peak power (1500 W); VC = 121 V @ 12.3 A; larger physical size (Case 017AB) | Used where higher surge energy (e.g., AC mains coupling) demands greater robustness than 600 W | Choose 1.5KE75A only if validated surge threat exceeds 600 W; otherwise P6KE75ARL offers optimal cost/performance balance. |
Compared with SMBJ75A and 1.5KE75A, the P6KE75ARL delivers best-in-class surge robustness per unit volume among 600 W axial TVS diodes, with UL 497B certification and Pb-free tape-and-reel delivery - making it ideal for certified industrial and medical systems requiring proven reliability and supply chain continuity.

FAQ
What is the maximum clamping voltage of the P6KE75ARL under surge conditions?
The P6KE75ARL has a maximum clamping voltage (VC) of 103 V when subjected to its rated peak pulse current of 5.8 A with a 1 ms waveform. This value is measured per Figure 4 in the official ON Semiconductor datasheet and defines the upper voltage limit imposed on protected circuitry during transient events. The P6KE75ARL maintains this clamping performance across its full operating temperature range.
Does the P6KE75ARL meet UL safety standards for isolated loop protection?
Yes, the P6KE75ARL is UL recognized under standard UL 497B (File #E210057, category QVGQ2) for isolated loop circuit protection. This certification covers the entire P6KE6.8A series, including the P6KE75ARL, and validates performance in strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge testing - critical for telecom and medical applications.
What is the working peak reverse voltage (VRWM) specification for the P6KE75ARL?
The P6KE75ARL has a working peak reverse voltage (VRWM) of 64.1 V, meaning it can continuously block up to this DC or peak AC voltage without entering breakdown. This parameter ensures compatibility with 48 V and 60 V nominal systems while providing margin for ripple and tolerance. Exceeding VRWM risks premature clamping or increased leakage in normal operation.
Is the P6KE75ARL supplied in Pb-free packaging?
Yes, the "RLG" suffix in P6KE75ARLG denotes Pb-free construction, and the P6KE75ARL variant is also Pb-free per ON Semiconductor's compliance documentation. Both versions use RoHS-compliant materials and are qualified for lead-free soldering at 260°C for 10 seconds - fully supporting modern environmental and manufacturing requirements.
How does the P6KE75ARL compare to bidirectional TVS diodes in surge protection?
The P6KE75ARL is unidirectional and optimized for DC or polarized signal lines where reverse conduction must be blocked during normal operation. Unlike bidirectional variants, it does not conduct in forward bias beyond ~3.5 V, making it unsuitable for AC lines. For DC power rails or unidirectional data lines like RS-485, the P6KE75ARL provides tighter VRWM control and lower capacitance than equivalent bidirectional parts.
