Product details
Overview
P6KE62AG 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 delivers 600 W peak pulse power at 1 ms, clamps at 85 V under 7.1 A peak pulse current, and features <1 ns response time with 53 V working peak reverse voltage - used in industrial power supplies and communication interfaces.
For engineers reviewing the P6KE62AG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥53 V, VC ≤85 V at IPP=7.1 A, low leakage (<5 µA @ VRWM), UL 497B recognition for isolated loop protection, and Pb-free axial lead compatibility with standard through-hole reflow.
Technical Context
The P6KE62AG operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 58.9–65.1 V breakdown range (VBR @ IT=1 A). Its clamping action limits transient-induced overvoltage to ≤85 V during 1 ms pulses, with thermal resistance of 20 °C/W enabling reliable surge dissipation without external heatsinking at TL ≤25 °C.
It complies with UL 497B for isolated loop circuit protection and meets Class 3 ESD immunity (>16 kV HBM). The device exhibits negligible capacitive delay but requires minimized PCB trace inductance to suppress overshoot - critical in fast-edge digital I/O and AC/DC front-end protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W @ 1 ms - sustains single high-energy surges common in lightning-induced or inductive-switching events |
| Working Peak Reverse Voltage (VRWM) | 53 V - sets maximum continuous operating voltage before clamping initiates |
| Clamping Voltage (VC) | 85 V @ IPP = 7.1 A - defines worst-case protected-circuit voltage during surge |
| Breakdown Voltage (VBR) | 58.9–65.1 V @ IT = 1 A - ensures predictable turn-on threshold across temperature and unit variation |
| Response Time | <1 ns - enables protection of high-speed logic and analog circuits before damage occurs |
| Leakage Current | <5 µA @ VRWM - avoids signal integrity degradation or standby power loss in low-power systems |
| ESD Rating | Class 3 (>16 kV HBM) - qualifies for direct handling in automated assembly without special ESD controls |
Pinout & Package
Surmetic-40 axial-leaded plastic package (Case 017AA), cathode indicated by polarity band; leads are solderable per J-STD-020, rated for 260 °C at 1/16″ from case for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during clamping | Connected to ground or low-impedance return path to shunt surge energy safely |
| Cathode | Protected line connection | Connected to input/output line requiring overvoltage protection; polarity band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Validated for isolated loop circuit protection - eliminates need for additional certification in telecom and industrial control designs |
| Pb-Free Construction | RoHS-compliant Surmetic-40 package - supports lead-free manufacturing without derating or process change |
| Low Temperature Coefficient | 0.104 %/°C on VBR - ensures stable clamping threshold across −55 to +150 °C operating range |
| High Surge Robustness | 100 A forward surge rating (IFSM) - withstands repetitive inrush or fault currents without degradation |
Applications
| Industrial Power Supply Input Protection | RS-485 Communication Line Protection |
|---|---|
Use Scenario: Protecting AC/DC converter inputs from line surges and load-dump transients in factory automation controllers. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed across DC bus rails to clamp overvoltage before it reaches rectifier, bulk capacitor, or controller IC. Use Value: Limits transient voltage to ≤85 V, preventing MOSFET gate oxide rupture and electrolytic capacitor overvoltage failure under IEC 61000-4-5 Level 4 stress. | Use Scenario: Safeguarding differential data lines in industrial PLC backplanes exposed to EFT and lightning-induced coupling. IC Role / Device Role / Timing Role: Paired unidirectional TVS devices (one per line) referenced to local ground, absorbing common-mode surges before receiver inputs. Use Value: Maintains RS-485 signal integrity by clamping transients within 1 ns while adding only ~10 pF capacitance - no data rate limitation up to 10 Mbps. |
| Medical Equipment Mains Interface | Automotive Body Control Module Inputs |
Use Scenario: Isolated power entry protection in diagnostic imaging equipment meeting UL 60601-1 creepage/clearance and surge requirements. IC Role / Device Role / Timing Role: Primary-side TVS on secondary winding of isolation transformer, referenced to earth ground to divert surge energy away from patient-connected circuits. Use Value: UL 497B listing confirms compliance for isolated loop protection - reduces design validation effort and accelerates regulatory submission. | Use Scenario: Protecting 12 V sensor inputs (e.g., door latch, seat position) from load dump and jump-start transients in automotive BCMs. IC Role / Device Role / Timing Role: Unidirectional TVS connected between sensor line and chassis ground, activated only during positive overvoltage events. Use Value: Withstands 7.1 A peak pulse at 85 V clamping, surviving ISO 7637-2 Pulse 5a (load dump) without degradation or latch-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | Surface-mount SMB package; 58 V VRWM; 600 W rating; 93.6 V VC @ 6.4 A | Requires PCB redesign for SMT placement; lower profile but higher thermal resistance (RθJA = 40 °C/W vs. 20 °C/W) | Select for space-constrained designs where board area is premium and thermal management allows SMT mounting. |
| 1.5KE62A | Same axial package; identical VRWM (53 V) and VC (85 V); 1500 W rating; larger physical size (Case 017AB) | Higher surge capacity but requires 30% more board space and different mounting hole pattern | Select when system-level surge testing exceeds IEC 61000-4-5 Level 4 and legacy axial footprint must be retained. |
Compared with SMBJ58A and 1.5KE62A, the P6KE62AG offers optimal balance of proven axial reliability, UL 497B certification, and compact Surmetic-40 footprint - making it preferred for cost-sensitive, through-hole industrial designs requiring certified loop protection.

FAQ
What is the clamping voltage of the P6KE62AG and how is it measured?
The P6KE62AG has a maximum clamping voltage (VC) of 85 V, measured at a peak pulse current (IPP) of 7.1 A with a 1 ms exponential waveform per Figure 4 in the datasheet. This value represents the worst-case voltage seen by downstream components during a surge event and is guaranteed across temperature and production lot variations.
Does the P6KE62AG meet UL safety standards for circuit protection?
Yes, the P6KE62AG is UL Recognized under UL 497B (File #E210057, QVGQ2 category) for isolated loop circuit protection. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown - confirming suitability for telecom, industrial control, and medical isolation barrier applications.
What is the meaning of the "G" suffix in P6KE62AG?
The "G" suffix in P6KE62AG indicates a Pb-free (RoHS-compliant) version of the Surmetic-40 axial package. It uses lead-free terminations and halogen-free molding compound, fully compatible with lead-free soldering processes per J-STD-020, without performance or reliability trade-offs versus the non-G variant.
Can the P6KE62AG be used in bidirectional protection circuits?
No, the P6KE62AG is strictly unidirectional. Its cathode-anode polarity means it only clamps positive transients on the cathode side relative to anode (ground). For bidirectional protection, a separate P6KE62CA (center-tap or complementary pair) or dedicated bidirectional TVS must be used - the P6KE62AG does not conduct or clamp in forward bias beyond its 3.5 V VF limit.
What is the thermal resistance and steady-state power rating of the P6KE62AG?
The P6KE62AG has a junction-to-lead thermal resistance (RJL) of 20 °C/W and a steady-state power dissipation (PD) of 5.0 W at TL ≤25 °C, derating linearly to zero at TL = 125 °C. This allows safe operation in ambient temperatures up to +150 °C when mounted with proper lead length (3/8″) and minimal thermal impedance to copper planes.
