Product details
Overview
1.5KE62A from ON Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics against ESD, lightning surges, and inductive switching transients. It features a 53 V working peak reverse voltage (VRWM), 62 V nominal breakdown voltage (VBR) at 1 mA, 85 V maximum clamping voltage (VC) at 17.7 A peak pulse current (IPP), and sub-nanosecond response time. It is used in power supply input stages, industrial I/O interfaces, and telecom line cards.
For engineers reviewing the 1.5KE62A datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, VRWM compatibility with DC bus voltage, surge current capability under 1 ms 8.3 ms waveform, and UL 497B recognition for isolated loop circuit protection.
Technical Context
The 1.5KE62A operates as a silicon avalanche diode with sharp Zener-like breakdown characteristics above VBR. Its clamping action begins at VRWM = 53 V and fully engages at VC = 85 V when subjected to IPP = 17.7 A per the standard 1 ms exponential pulse (Figure 5). Thermal resistance is 20 °C/W junction-to-lead, enabling 5.0 W steady-state dissipation at TL ≤ 75 °C with 3/8″ lead length.
It exhibits low leakage (<5 µA at VRWM), 0.104 %/°C VBR temperature coefficient, and ESD robustness exceeding 16 kV per Human Body Model (HBM). The device is housed in a void-free Surmetic axial-leaded plastic package (Case 41A) with cathode band polarity marking and Pb-free plating compliant with RoHS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W @ 1 ms - sustains single high-energy transients without failure |
| Working Peak Reverse Voltage (VRWM) | 53 V - maximum continuous DC or peak AC voltage the device blocks before clamping |
| Breakdown Voltage (VBR) | 62 V ±5% @ 1 mA - precise avalanche onset threshold for predictable clamping initiation |
| Clamping Voltage (VC) | 85 V @ 17.7 A IPP - maximum voltage seen by protected circuit during full-rated surge |
| Response Time | <1 ns - enables suppression before most ICs experience overstress |
| Leakage Current | <5 µA @ 53 V - negligible standby power loss and signal integrity impact |
| UL Recognition | UL 497B QVGQ2 - certified for isolated loop circuit protection in safety-critical systems |
Pinout & Package
1.5KE62A uses an axial-leaded plastic package (ON Semiconductor Case 41A, JEDEC DO-201AD), with cathode identified by a colored band. Leads are tinned, solderable, and rated for 260 °C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-potential rail; completes clamping path during transient |
| Cathode | High-side connection point | Marked with band; connected to protected line; conducts avalanche current into ground |
Key Features

Applications
| Industrial PLC I/O Protection | AC/DC Power Supply Input |
|---|---|
Use Scenario: 24 V DC digital input module exposed to field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input terminal and common rail to clamp transients before reaching optocoupler or MCU GPIO. Use Value: Limits voltage to ≤85 V during 17.7 A surge, preserving optocoupler CTR and preventing MCU latch-up or damage. | Use Scenario: Secondary-side DC bus (48 V) in telecom power supply subject to lightning-induced ring waves. IC Role / Device Role / Timing Role: Primary overvoltage clamp on output rail, coordinated with upstream MOV and fuse. Use Value: Clamps 1500 W surges within 1 ns, reducing downstream capacitor stress and avoiding regulator shutdown. |
| Medical Equipment Signal Lines | Automotive Body Control Module Inputs |
Use Scenario: RS-485 communication lines between patient monitor and bedside unit in hospital environments. IC Role / Device Role / Timing Role: Line-to-ground TVS on each differential pair, referenced to isolated signal ground. Use Value: UL 497B recognition ensures compliance with medical isolation barrier standards while suppressing EFT bursts up to 4 kV. | Use Scenario: 12 V sensor inputs (e.g., door switch, seatbelt latch) in BCM exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on each input, placed adjacent to connector. Use Value: With VRWM = 53 V, it remains non-conducting during 14 V alternator regulation but clamps 120 V load dump spikes to safe levels. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Lower peak power (600 W), smaller SMB package (surface-mount), 64 V VRWM, 104 V VC @ 5.8 A | Not suitable for 1500 W surge events; limited to board-level ESD and lower-energy transients | Select when space-constrained PCB layout requires SMT and surge threat level is ≤IEC 61000-4-2 Level 4 |
| 1N6290AG | Same die, identical electrical specs, Pb-free axial package - direct ON Semiconductor variant of 1.5KE62A | No functional difference; differs only in ordering code and packaging format (tape & reel vs. bulk box) | Choose for automated assembly with tape-and-reel feed or when sourcing from ON's preferred part list |
Compared with SMBJ64A, the 1.5KE62A delivers 2.5× higher surge energy handling and axial through-hole mounting for high-reliability chassis connections; compared with 1N6290AG, it shares identical protection performance but differs in packaging logistics and orderable part number formatting.

FAQ
What is the clamping voltage of the 1.5KE62A under maximum rated surge current?
The 1.5KE62A has a maximum clamping voltage (VC) of 85 V when subjected to its rated peak pulse current (IPP) of 17.7 A, measured using the standard 1 ms exponential waveform per Figure 5 of the datasheet. This value defines the upper voltage limit imposed on the protected circuit during worst-case transient events and must be verified against the absolute maximum ratings of downstream components to ensure safe operation.
Is the 1.5KE62A suitable for bidirectional transient protection?
No, the 1.5KE62A is a unidirectional TVS diode, designed only for clamping positive transients relative to ground. It conducts in avalanche mode when cathode voltage exceeds anode by ≥62 V but blocks reverse voltage up to −53 V. For bidirectional protection-such as AC lines or differential data buses-a symmetric device like 1.5KE62CA or separate back-to-back configuration is required.
Does the 1.5KE62A meet UL 497B certification?
Yes, the 1.5KE62A is UL Recognized under file QVGQ2 to UL 497B for protectors, covering isolated loop circuit applications. This certification confirms successful completion of strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge testing-validating its use in safety-critical telecom and industrial isolation barriers without requiring additional third-party evaluation.
What is the thermal resistance and steady-state power rating of the 1.5KE62A?
The 1.5KE62A has a junction-to-lead thermal resistance (RJL) of 20 °C/W and a steady-state power dissipation (PD) rating of 5.0 W at lead temperature (TL) ≤ 75 °C with 3/8″ lead length. Derating is linear at 20 mW/°C above TL = 75 °C. These parameters govern continuous power handling in non-transient conditions, such as leakage-based heating or sustained overvoltage scenarios.
How does the 1.5KE62A compare to the 1N6290AG in terms of electrical performance?
The 1.5KE62A and 1N6290AG are electrically identical: both specify VRWM = 53 V, VBR = 62 V (min 58.9 V, max 65.1 V), VC = 85 V @ 17.7 A, and share the same Surmetic axial package (Case 41A). The 1N6290AG is ON Semiconductor's JEDEC-registered part number for the same device, with "G" denoting Pb-free compliance and "AG" indicating bulk packaging-no performance or reliability differences exist between them.
