Product details
Overview
1.5KE100ARL4 from ON Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) diode designed for parallel protection of sensitive electronics against ESD, lightning surges, and inductive switching transients. It features a 85.5 V working peak reverse voltage (VRWM), 100 V breakdown voltage (VBR) at 1 mA test current, and clamps to 137 V at 11 A peak pulse current, making it suitable for industrial power supply input protection and telecom line interface circuits.
For engineers reviewing the 1.5KE100ARL4 datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin over operating DC voltage, clamping voltage vs. protected IC's absolute maximum rating, surge current capability under 1 ms pulse, and UL 497B recognition for isolated loop circuit compliance.
Technical Context
This device operates as a silicon avalanche diode with fast turn-on response (<1 ns) and low dynamic impedance, enabling effective suppression of sub-microsecond transients. Its unidirectional configuration provides reverse-biased clamping only, requiring correct polarity placement across the protected line-to-ground path.
The 1.5KE100ARL4 uses a Surmetic axial-leaded plastic package (Case 41A) with Pb-free terminations and is rated for 1500 W non-repetitive peak pulse power per 1 ms waveform (Figure 5), with thermal derating above 75°C lead temperature and steady-state dissipation limited to 5.0 W at TL ≤ 75°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 85.5 V - Maximum continuous reverse operating voltage before clamping begins; must exceed system DC bus or signal swing. |
| VBR @ IT=1 mA | 100 V (min) to 105 V (max) - Breakdown threshold range defining onset of avalanche conduction. |
| VC @ IPP=11 A | 137 V - Clamped voltage during 1 ms surge; determines maximum stress on downstream components. |
| PPK | 1500 W @ 1 ms - Peak transient energy absorption capacity; defines single-event surge robustness. |
| IR @ VRWM | 5 μA max - Reverse leakage at working voltage; ensures minimal standby power loss and signal integrity. |
| Response Time | <1 ns - Enables suppression of fast-rising ESD events before protected circuitry responds. |
| UL Recognition | UL 497B QVGQ2 - Certified for isolated loop circuit protection, including strike voltage and endurance testing. |
Pinout & Package
1.5KE100ARL4 is housed in an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a colored band. Leads are tin-plated, solderable at 260°C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground-reference terminal | Connected to system ground or low-impedance return path; forms clamping path during reverse transient. |
| Cathode | Line-protection terminal | Connected to protected line (e.g., DC input, signal line); polarity band marks this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges without degradation. |
| ESD rating >16 kV HBM | Meets or exceeds Class 3 ESD immunity requirements for end-equipment qualification. |
| Low zener impedance | Minimizes voltage overshoot during fast transients, improving clamping precision under high di/dt. |
| UL 497B certification | Validates suitability for safety-critical telecom and industrial isolated loop applications. |
| Pb-free axial package | Complies with RoHS Directive 2011/65/EU and supports automated through-hole assembly. |
Applications
| Industrial Power Supply Input Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: 48 V DC input stage of programmable logic controller (PLC) power module exposed to load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp transients before they reach upstream rectifier and downstream DC-DC controller. Use Value: Clamps 137 V at 11 A ensures protected 60 V-rated MOSFETs and controllers remain within safe operating area during 1 ms surges. | Use Scenario: T1/E1 line interface card in central office equipment subject to lightning-induced longitudinal surges. IC Role / Device Role / Timing Role: Primary protection element on tip/ring pair, coordinated with gas discharge tube (GDT) and series impedance for hybrid surge filtering. Use Value: UL 497B recognition confirms compliance with isolation barrier requirements for telecom safety standards. |
| Medical Equipment AC/DC Adapter Input | Automotive Body Control Module (BCM) Power Rail |
Use Scenario: Secondary-side DC output (24 V) of medical-grade AC/DC adapter feeding patient-monitoring analog front-end. IC Role / Device Role / Timing Role: Final-stage transient clamp after filter inductors, safeguarding low-noise op-amps and ADC references from conducted noise. Use Value: 5 μA max leakage at 85.5 V prevents signal offset drift and maintains microamp-level bias stability. | Use Scenario: 12 V battery rail in BCM exposed to ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 2a (load dump). IC Role / Device Role / Timing Role: Parallel-connected TVS on main power input, selected for VRWM ≥ 85.5 V to tolerate cold-crank undervoltage while clamping load dump spikes. Use Value: 1500 W rating handles 100 A/100 ms load dump events when used with appropriate upstream fusing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Lower peak power (600 W), SMC package, 100 V VBR min, 156 V VC @ 3.8 A | Better suited for space-constrained PCBs; insufficient for 1500 W surge events | Select 1.5KE100ARL4 when 1 ms surge energy exceeds 1.5 J or UL 497B certification is mandatory |
| 1N6295AG | Same family, identical electrical specs, but packaged in 500-unit box instead of 1500-unit tape-and-reel | No functional difference; differs only in packaging format and ordering unit | Choose 1.5KE100ARL4 for automated pick-and-place production; select 1N6295AG for manual prototyping or low-volume repair |
Compared with SMBJ100A, the 1.5KE100ARL4 delivers 2.5× higher surge energy handling and certified isolation-loop compliance; versus 1N6295AG, it offers identical protection performance but optimized for high-volume SMT assembly via tape-and-reel delivery.

FAQ
What is the clamping voltage of the 1.5KE100ARL4 under standard surge conditions?
The 1.5KE100ARL4 clamps to a maximum of 137 V when subjected to its rated 11 A peak pulse current (IPP), measured using the standardized 1 ms exponential waveform per Figure 5 in the datasheet. This value defines the upper voltage limit imposed on protected circuitry during transient events and must be compared directly against the absolute maximum ratings of downstream components to ensure safe operation.
Does the 1.5KE100ARL4 meet UL safety standards for isolated circuit protection?
Yes, the 1.5KE100ARL4 carries UL 497B recognition (File #E210057, category QVGQ2) for protectors used in isolated loop circuits. This certification covers rigorous testing including strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge performance-validating its use in telecom, industrial control, and medical systems requiring reinforced insulation barriers.
What is the maximum steady-state power dissipation rating for the 1.5KE100ARL4?
The 1.5KE100ARL4 has a steady-state power dissipation rating of 5.0 W at a lead temperature (TL) of ≤75°C, with thermal derating at 20 mW/°C above that temperature. This rating applies only to continuous DC or low-frequency reverse bias conditions-not transient suppression-and must be verified against actual board layout, copper area, and ambient conditions in the final design.
How does the 1.5KE100ARL4 differ from the 1N6295AG variant?
The 1.5KE100ARL4 and 1N6295AG share identical electrical specifications, thermal characteristics, and mechanical dimensions. The sole difference is packaging: 1.5KE100ARL4 ships in 1500-unit tape-and-reel format optimized for automated assembly, whereas 1N6295AG is supplied in 500-unit boxes for manual handling or low-volume use. Both are Pb-free and fully interchangeable electrically.
Can the 1.5KE100ARL4 be used in bidirectional transient protection applications?
No, the 1.5KE100ARL4 is a unidirectional TVS diode and conducts only in reverse breakdown. For bidirectional protection (e.g., AC lines or data buses), a symmetric device such as the 1.5KE100A (dual-diode configuration) or separate back-to-back unidirectional devices would be required. Using 1.5KE100ARL4 in forward bias risks permanent damage due to excessive forward current beyond its 200 A surge rating.
