Product details
Overview
P6KE62ARL from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic-40 package, rated for 600 W peak pulse power at 1 ms, with 53 V working peak reverse voltage (VRWM), 62 V nominal breakdown voltage (VBR), and 85 V maximum clamping voltage (VC) at 7.1 A peak pulse current (IPP). It protects power supplies and industrial control circuits against ESD and lightning-induced transients.
For engineers reviewing the P6KE62ARL datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥ system DC bus voltage, VC margin below IC absolute maximum ratings, low leakage (<5 µA @ VRWM), UL 497B recognition for isolated loop protection, and sub-1 ns response time for fast transient suppression.
Technical Context
The P6KE62ARL operates as a silicon avalanche diode, entering conduction when reverse voltage exceeds its 62 V breakdown threshold (VBR), clamping transient energy to ≤85 V at 7.1 A. Its thermal resistance (RJL = 20 °C/W) and 5.0 W steady-state power rating enable reliable operation under repeated surge conditions when mounted with 3/8″ lead length.
Designed for parallel protection of DC rails, it exhibits <1 ns intrinsic response time and negligible junction inductance-though external PCB layout (short leads, proximity to protected IC) critically determines actual overshoot performance. UL 497B recognition confirms compliance for isolated loop circuit protection in telecom and industrial systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W @ 1 ms pulse - sustains single high-energy surges without failure |
| Working Peak Reverse Voltage | 53 V - maximum continuous DC or peak AC voltage before clamping initiates |
| Breakdown Voltage | 62 V (nominal) @ 1 mA test current - precise avalanche turn-on threshold |
| Clamping Voltage | 85 V @ 7.1 A IPP - limits transient voltage seen by downstream components |
| Leakage Current | <5 µA @ 53 V - minimal standby power loss and signal integrity impact |
| Response Time | <1 ns - enables suppression of nanosecond-scale ESD events |
| ESD Rating | Class 3 (>16 kV HBM) - meets IEC 61000-4-2 Level 4 immunity requirements |
Pinout & Package
Surmetic-40 axial-leaded plastic package (Case 017AA), cathode indicated by polarity band. Leads are solderable per J-STD-020, max solder temperature 260°C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to system ground or lower-potential rail in unidirectional TVS configuration |
| Cathode | Protected line connection | Connected to the line being protected (e.g., +12 V rail); polarity band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Validated for isolated loop circuit protection - eliminates need for separate certification testing in telecom/industrial designs |
| Low Clamping Ratio (VC/VBR) | 1.37 (85 V / 62 V) - tight voltage margin ensures robust protection without over-clamping |
| Pb-Free Packaging Option | P6KE62ARLG variant available - supports RoHS-compliant manufacturing without derating or performance trade-offs |
| Temperature Coefficient of VBR | 0.104 %/°C - predictable VBR drift over −55°C to +150°C operating range |
Applications
| Industrial Power Supply Protection | Medical Equipment Input Stage |
|---|---|
Use Scenario: 48 V 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 across input terminals to clamp surges before they reach upstream rectifier and downstream DC-DC controller. Use Value: 85 V clamping voltage ensures MOSFETs and controllers rated for 100 V abs max remain within safe operating area during 100 V/100 A surge events. | Use Scenario: Patient-connected sensor interface in diagnostic imaging equipment requiring isolation barrier compliance per IEC 60601-1. IC Role / Device Role / Timing Role: UL 497B-recognized TVS on secondary side of isolated DC-DC converter powering analog front-end. Use Value: Certified protection enables direct integration into safety-critical isolated loops without additional barrier validation overhead. |
| Telecom Line Interface | Automotive Body Control Module |
Use Scenario: RS-485 data line in base station remote radio unit subjected to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Paired unidirectional TVS devices (one per line) referenced to isolated ground plane to suppress differential and common-mode transients. Use Value: Sub-1 ns response prevents data corruption during 8/20 µs surges; low capacitance avoids signal integrity degradation at 10 Mbps. | Use Scenario: 12 V battery rail in BCM exposed to ISO 7637-2 Pulse 1 (−150 V/50 Ω) and Pulse 3a (−200 V/50 Ω) transients.

Use Value: 600 W peak power rating withstands repetitive automotive load dump pulses without parametric shift or catastrophic failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | Surface-mount SMB package; 60 V VRWM; 93 V VC @ 6.5 A IPP; 600 W rating | Requires PCB rework for SMT vs. through-hole; higher VC reduces margin for 60 V systems | Select when board space constraints mandate SMT or automated assembly is required |
| 1.5KE62A | Same axial package but 1.5 kW rating; 53 V VRWM; 100 V VC @ 15 A IPP; higher thermal mass | Over-spec'd for 600 W use cases; larger physical size may conflict with mechanical clearance | Select only when legacy 1.5KE footprint compatibility is mandatory or multi-pulse endurance beyond 600 W is verified |
Compared with SMBJ60A and 1.5KE62A, the P6KE62ARL offers optimal balance of through-hole manufacturability, UL 497B certification, and precise 85 V clamping for 48–60 V DC systems-without over-engineering thermal capacity or sacrificing safety compliance.

FAQ
What is the maximum clamping voltage of the P6KE62ARL and under what test condition?
The P6KE62ARL has a maximum clamping voltage (VC) of 85 V, measured at a peak pulse current (IPP) of 7.1 A using a 1 ms exponential waveform per Figure 4 in the datasheet. This value defines the highest voltage the device allows to pass through during a transient event, directly protecting downstream components rated for 100 V absolute maximum.
Does the P6KE62ARL meet UL safety standards, and which standard applies?
Yes, the P6KE62ARL is UL Recognized under UL 497B (File #E210057) for protector applications in isolated loop circuits. This certification covers tests including strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge performance-validating its suitability for telecom and industrial isolation barriers where safety-critical transient suppression is required.
What is the operating temperature range for the P6KE62ARL, and how does thermal derating affect its power handling?
The P6KE62ARL operates from −55°C to +150°C. Its steady-state power dissipation is derated linearly above 50°C ambient: 5.0 W at ≤50°C, decreasing by 50 mW/°C up to 150°C. For pulsed operation, peak power remains 600 W at TL ≤25°C but must be reduced per Figure 2's derating curve when lead temperature exceeds 25°C.
How does the P6KE62ARL differ from the P6KE62A and P6KE62ARLG variants?
The P6KE62ARL is identical in electrical and thermal specifications to P6KE62A but supplied in tape-and-reel (4000 units) instead of bulk box. The P6KE62ARLG adds Pb-free plating while maintaining all performance parameters-including UL 497B recognition-making it compliant with RoHS Directive 2011/65/EU without design or qualification changes to the P6KE62ARL.
Can the P6KE62ARL be used in bidirectional protection configurations?
No-the P6KE62ARL is a unidirectional TVS diode, designed only for reverse-biased operation with cathode connected to the protected line. For bidirectional protection (e.g., AC lines or data buses), a dedicated bidirectional device such as P6KE62CA or SMAJ62CA must be used; substituting P6KE62ARL would result in forward conduction and potential failure during positive half-cycle transients.
