Product details
Overview
P6KE75ARLG 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 600 W peak pulse power (1 ms), 75.05 V breakdown voltage at 1 mA test current, 103 V maximum clamping voltage at 5.8 A peak pulse current, and <1 ns response time. It protects power supplies, industrial controls, and communication interfaces against ESD and lightning-induced surges.
For engineers reviewing the P6KE75ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (64.1 V), clamping performance under 5.8 A surge, Pb-free tape-and-reel packaging (4000 units), and UL 497B recognition for isolated loop circuit protection.
Technical Context
The P6KE75ARLG operates as a silicon avalanche diode with unidirectional polarity, activated when reverse voltage exceeds its 71.3–78.8 V breakdown range. Its clamping action limits transient voltages to ≤103 V at 5.8 A, with low leakage (<5 µA at 64.1 V) and a temperature coefficient of 0.105 %/°C for stable VBR over temperature.
It uses a thermoset plastic case (Case 017AA), rated for −55 °C to +150 °C operation, with 20 °C/W junction-to-lead thermal resistance and 100 A forward surge capability (8.3 ms half-sine). The cathode band identifies polarity, and mounting position is unrestricted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W @ 1 ms - sustains single high-energy transients without failure |
| Working Peak Reverse Voltage | 64.1 V - sets minimum operating voltage threshold before clamping begins |
| Breakdown Voltage | 71.3–78.8 V @ 1 mA - defines precise avalanche onset range for reliable triggering |
| Clamping Voltage | 103 V @ 5.8 A - maximum voltage imposed on protected circuit during worst-case surge |
| Response Time | <1 ns - ensures suppression before sensitive downstream components experience overvoltage |
| ESD Rating | Class 3 (>16 kV HBM) - meets stringent electrostatic discharge immunity requirements |
| UL Recognition | UL 497B (QVGQ2) - certified for isolated loop circuit protection in safety-critical systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Surface-mount SMB package; same 75 V VBR range but 600 W rating at 10/1000 µs waveform | Requires PCB redesign for SMT placement; better high-frequency response due to lower parasitic inductance | Select when board space is constrained and automated assembly is preferred |
| 1.5KE75A | Higher 1.5 kW peak power rating; larger DO-201AD package; identical VBR and clamping specs | Used where higher surge repetition or longer pulse durations (e.g., 10 ms) are expected | Select when legacy through-hole footprint compatibility is required and 1.5 kW headroom is needed |
Compared with SMBJ75A and 1.5KE75A, the P6KE75ARLG offers optimal balance of axial-leaded manufacturability, UL 497B certification for loop protection, and cost-effective 600 W surge handling - making it ideal for volume industrial power and interface designs where tape-and-reel supply and proven reliability are prioritized.

FAQ
What is the clamping voltage of the P6KE75ARLG at its rated peak pulse current?
The P6KE75ARLG has a maximum clamping voltage (VC) of 103 V when subjected to its specified peak pulse current (IPP) of 5.8 A, measured using the 1 ms exponential waveform per Figure 4 in the datasheet. This value ensures protected circuits remain within safe operating limits during transient events. The P6KE75ARLG's low clamping ratio supports robust design margins for downstream components.
Is the P6KE75ARLG RoHS-compliant and halogen-free?
Yes, the P6KE75ARLG is a Pb-free (RoHS-compliant) device, as indicated by the "G" and "RLG" suffixes in its ordering code. ON Semiconductor confirms compliance with JEDEC JS709 and IPC-1752 standards for halogen content. The P6KE75ARLG's Surmetic-40 package uses thermosetting plastic with corrosion-resistant, solderable leads - fully aligned with modern environmental and manufacturing requirements.
Can the P6KE75ARLG be used in bidirectional protection configurations?
No, the P6KE75ARLG is a unidirectional TVS diode and must be used with correct polarity - cathode connected to the line being protected. For bidirectional protection, two P6KE75ARLG devices may be connected anode-to-anode, but this is not recommended due to asymmetric clamping behavior. The P6KE75A series does not include a factory-bidirectional variant; use CA-suffix parts (e.g., P6KE75CA) instead for true bidirectional operation.
What is the maximum steady-state power dissipation for the P6KE75ARLG?
The P6KE75ARLG has a steady-state power dissipation (PD) of 5.0 W at lead temperature (TL) ≤ 25 °C, derating linearly above 50 °C at 50 mW/°C. This rating applies only to continuous DC or low-frequency conditions - the device is intended for transient suppression, not sustained power dissipation. Thermal design must ensure TL remains within limits; the P6KE75ARLG's 20 °C/W RJL requires adequate lead heatsinking for repeated surges.
Does the P6KE75ARLG meet UL 497B requirements for isolated loop circuits?
Yes, the P6KE75ARLG is explicitly covered under ON Semiconductor's UL 497B recognition (File #E210057, Category QVGQ2) for isolated loop circuit protection - confirmed in the datasheet's Application Notes section. This certification validates its use in safety-isolated interfaces such as 4–20 mA loops, fieldbus segments, and other galvanically separated systems where transient suppression must not compromise insulation integrity. The P6KE75ARLG's construction and testing satisfy all required dielectric withstand, endurance, and strike voltage tests.
