Product details
Overview
1.5KE62ARL4G 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), 85 V maximum clamping voltage (VC) at 17.7 A peak pulse current (IPP), and sub-1 ns response time - deployed in power supply input stages, industrial I/O interfaces, and telecom line cards.
For engineers reviewing the 1.5KE62ARL4G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin relative to protected IC VMAX, VRWM alignment with DC bus voltage, surge current capability under 1 ms 8.3 ms waveform, and UL 497B recognition for isolated loop circuit compliance.
Technical Context
This device operates as a silicon avalanche diode in reverse-biased mode, entering controlled breakdown when transient voltage exceeds VBR (58.9–65.1 V). Its low dynamic impedance (<1 Ω typical near IPP) ensures stable clamping during high-energy pulses, while the Surmetic axial leaded package (Case 41A) provides robust thermal conduction via leads rated for 260°C soldering.
It complies with Class 3 HBM ESD rating (>16 kV), meets UL 497B for isolated loop protection, and is characterized per non-repetitive 1 ms pulse (Figure 5 waveform) with derating above 25°C ambient or 75°C lead temperature - requiring layout-aware placement near protected nodes to minimize parasitic inductance-induced overshoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 53 V - Maximum continuous reverse operating voltage before leakage exceeds 5 µA; sets minimum system DC bus tolerance. |
| VBR @ IT=1 A | 58.9–65.1 V - Breakdown range defining turn-on threshold; used to verify margin over VRWM and protected IC absolute max rating. |
| VC @ IPP=17.7 A | 85 V - Clamped voltage during full 1500 W surge; determines maximum stress on downstream components. |
| PPK | 1500 W @ 1 ms - Peak pulse power handling per JEDEC test waveform; defines single-event surge survivability. |
| Response Time | <1 ns - Avalanche initiation delay; enables suppression before logic-level transients damage CMOS/MOS inputs. |
| ESD Rating | Class 3 HBM (>16 kV) - Confirmed human-body-model immunity; supports robustness validation in end-equipment ESD testing. |
| UL Recognition | UL 497B QVGQ2 - Certified for isolated loop circuit protection; satisfies safety agency requirements for telecom and industrial interfaces. |
Pinout & Package
1.5KE62ARL4G uses an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a polarity band. Leads are tin-plated copper, solderable at 260°C for 10 seconds at 1/16″ from case. Mounting position is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or lowest potential rail; completes clamping path during transient events. |
| Cathode | High-side transient sensing node | Connected to protected line (e.g., +12 V rail); avalanche conduction begins here when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges without external series impedance. |
| 85 V clamping at 17.7 A | Provides ≥20% margin below typical 100 V absolute max ratings of industrial-grade DC-DC controllers and interface ICs. |
| UL 497B certification | Validates suitability for telecom line interface protection where isolation barrier integrity must be maintained during surge events. |
| Sub-1 ns response | Minimizes voltage overshoot in high-speed digital I/O protection, especially critical for RS-485/RS-232 transceivers with <100 ns propagation delays. |
| Pb-free axial package | Complies with RoHS Directive 2011/65/EU and supports wave-solder reflow compatibility in legacy through-hole manufacturing. |

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 | Surface-mount SMB package; 64 V VRWM; 1000 W PPK; 104 V VC @ 9.6 A | Lower power rating and higher clamping voltage; suited for PCB space-constrained designs with lower surge exposure. | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3 (2 kV/2 Ω). |
| 1.5KE62A | Same electrical specs and axial package; differs only in packaging format (bulk vs. tape-and-reel) | No functional difference; identical performance and mounting; differs only in logistics and assembly handling. | Choose 1.5KE62A for manual prototyping or low-volume hand-soldering; 1.5KE62ARL4G for automated pick-and-place. |
Compared with SMBJ64A, 1.5KE62ARL4G delivers 50% higher surge power handling and 19 V lower clamping voltage - critical for protecting 60 V-rated gate drivers. Compared with 1.5KE62A, it offers identical protection performance but optimized for high-volume SMT assembly via 1500-unit tape-and-reel packaging.

FAQ
What is the clamping voltage of the 1.5KE62ARL4G and how is it measured?
The 1.5KE62ARL4G has a maximum clamping voltage (VC) of 85 V, measured at a peak pulse current (IPP) of 17.7 A using the standardized 1 ms exponential waveform defined in Figure 5 of the datasheet. This value represents the highest voltage the device allows across its terminals during a full 1500 W transient event - a critical parameter for ensuring protected ICs remain within their absolute maximum voltage ratings. The 1.5KE62ARL4G achieves this clamping performance with low dynamic impedance and sub-1 ns response.
Does the 1.5KE62ARL4G meet UL safety standards for circuit protection?
Yes, the 1.5KE62ARL4G is UL recognized under standard UL 497B (File #E210057, category QVGQ2) for isolated loop circuit protection. This certification covers rigorous testing including strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge performance - confirming its suitability for telecom, industrial control, and medical applications where regulatory compliance is mandatory. The 1.5KE62ARL4G shares this UL recognition with the full 1.5KE6.8A–1.5KE250A series.
What is the working peak reverse voltage (VRWM) of the 1.5KE62ARL4G and why does it matter?
The 1.5KE62ARL4G has a VRWM of 53 V - the maximum continuous DC or peak AC voltage the device can block without exceeding 5 µA leakage current. This parameter is essential for proper selection: VRWM must be ≥ the normal operating voltage of the protected line (e.g., 48 V DC bus) to prevent false triggering, while remaining low enough to ensure timely clamping before downstream components fail. The 1.5KE62ARL4G's 53 V VRWM provides optimal margin for 48 V systems and compatibility with 60 V-rated interface ICs.
How does the 1.5KE62ARL4G differ from the 1.5KE62A variant?
The 1.5KE62ARL4G and 1.5KE62A share identical electrical specifications, thermal characteristics, mechanical dimensions, and surge performance - differing only in packaging format. The "RL4G" suffix denotes 1500-unit tape-and-reel packaging optimized for automated SMT assembly, while "A" indicates bulk or box packaging (500 units) intended for manual or low-volume placement. Both use the same Surmetic axial Case 41A package and Pb-free construction. The 1.5KE62ARL4G is functionally interchangeable with 1.5KE62A in all circuit applications.
Is the 1.5KE62ARL4G suitable for protecting RS-485 transceivers?
Yes, the 1.5KE62ARL4G is widely used for RS-485 transceiver protection due to its 85 V clamping voltage, which stays well below the 100 V absolute maximum rating of devices like the MAX1487 or SN65HVD7x families. Its sub-1 ns response prevents overshoot during fast transients, and its 1500 W rating handles IEC 61000-4-4 EFT bursts and induced surges on long bus runs. For optimal performance, place the 1.5KE62ARL4G within 2 mm of the transceiver pins with minimal trace inductance - a practice validated in ON Semiconductor application notes AN-1040 and AN-1052.
