Product details
Overview
1N6276ARL4 from ON Semiconductor is a unidirectional 1500 W Mosorb transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics. It features a 13.6 V working peak reverse voltage (VRWM), 16 V breakdown voltage (VBR) at 1 mA test current, and clamps to 22.5 V at 67 A peak pulse current - ideal for safeguarding power supply rails and I/O lines in industrial control systems.
For engineers reviewing the 1N6276ARL4 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin relative to system operating voltage, surge current handling under 1 ms pulses, UL 497B recognition for isolated loop protection, and Pb-free axial lead compatibility with wave soldering at 230°C.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified VBR (15.2–16.8 V). Its low dynamic impedance and sub-1 ns response time enable rapid voltage clamping during ESD or lightning-induced transients.
Designed for single-pulse suppression per IEC 61000-4-5 waveform (1.2/50 μs voltage, 8/20 μs current), it delivers 1500 W peak power at TL ≤ 25°C and derates linearly above 75°C ambient, with thermal resistance of 20°C/W from junction to lead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 13.6 V - maximum continuous reverse operating voltage before clamping begins |
| VBR @ IT=1 mA | 15.2–16.8 V - precise breakdown threshold ensuring reliable turn-on without premature conduction |
| VC @ IPP=67 A | 22.5 V - clamped voltage during 1 ms surge, defining worst-case overvoltage seen by protected circuit |
| PPK | 1500 W - peak transient power dissipation capability under standardized 1 ms pulse |
| IR @ VRWM | <5 μA - negligible leakage current preserving signal integrity and power efficiency |
| Response Time | <1 ns - enables suppression before fast transients damage CMOS/MOS/Bipolar ICs |
| ESD Rating | Class 3 (>16 kV HBM) - meets stringent electrostatic discharge immunity requirements |
Pinout & Package
Package: Axial leaded Surmetic plastic case (Case 41A), void-free transfer-molded thermoset, cathode indicated by polarity band, lead finish Pb-free, rated for 230°C soldering (1/16″ from case, 10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink (reverse bias) | Connected to ground or low-impedance return path during transient clamping |
| Cathode | Current source (reverse bias) | Connected to protected line; polarity band identifies this terminal for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Qualified for isolated loop circuit protection - supports safety-critical telecom and medical equipment compliance |
| 1500 W Peak Pulse Power | Withstands high-energy surges (e.g., induced lightning, inductive switching) without degradation |
| Low Clamping Ratio (VC/VBR ≈ 1.41) | Minimizes overvoltage stress on downstream components while maintaining robust margin |
| Pb-Free Axial Leads | Complies with RoHS and JEDEC J-STD-020 reflow/soldering standards for automated assembly |
| Surmetic Package Reliability | Void-free molding ensures consistent thermal performance and long-term mechanical stability under thermal cycling |
Applications
| Industrial Power Supply Protection | Medical Equipment I/O Isolation |
|---|---|
Use Scenario: Protecting 12 V DC input rails in programmable logic controllers against load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed in parallel with input filter capacitor to clamp transients before they reach DC-DC converters. Use Value: Limits voltage excursion to 22.5 V during 67 A surges, preventing latch-up or gate oxide rupture in downstream regulators. | Use Scenario: Safeguarding analog sensor inputs in patient monitoring devices connected to isolated front-end circuits. IC Role / Device Role / Timing Role: Transient suppressor on isolated signal lines compliant with UL 497B for loop-powered sensors. Use Value: Provides certified surge immunity up to 1500 W without compromising galvanic isolation integrity or signal fidelity. |
| Telecom Line Interface Protection | Process Control Signal Conditioning |
Use Scenario: Shielding RS-485 transceivers in base station backhaul links from induced surges on long cable runs. IC Role / Device Role / Timing Role: Primary clamping device on differential bus lines, coordinated with common-mode chokes. Use Value: Sub-1 ns response ensures clamping occurs before transceiver ESD structures are overstressed, preserving data integrity. | Use Scenario: Protecting 4–20 mA current loop inputs in PLC analog modules from field wiring transients. IC Role / Device Role / Timing Role: Reverse-biased TVS across loop terminals to shunt surge energy away from precision op-amp input stages. Use Value: Low leakage (<5 μA) avoids loading the current loop; 13.6 V VRWM matches typical loop supply headroom. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Surface-mount SMC package; 600 W PPK; 16 V VBR; 25.5 V VC @ 23.3 A | Lower surge rating and different mounting - suited for space-constrained PCBs but not direct replacement for axial leaded designs | Select SMBJ16A only when board layout allows SMT placement and 600 W surge capacity suffices |
| 1N6276A | Same electrical specs and case 41A package; differs only in packaging - bulk (500/unit box) vs. tape-and-reel (1500/unit) | No functional difference; identical performance and footprint - interchangeability confirmed by ON Semi ordering matrix | Choose 1N6276A for manual prototyping or low-volume assembly; 1N6276ARL4 for automated pick-and-place |
Compared with SMBJ16A, 1N6276ARL4 offers 2.5× higher surge power and proven axial reliability in high-vibration environments; versus 1N6276A, it provides identical protection with optimized logistics for high-volume production.

FAQ
What is the clamping voltage of the 1N6276ARL4 under maximum surge conditions?
The 1N6276ARL4 clamps to 22.5 V when subjected to its rated peak pulse current of 67 A, measured per the standard 1 ms exponential decay waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is validated per ON Semiconductor's test methodology in the 1N6267A Series datasheet Rev. 6.
Is the 1N6276ARL4 RoHS-compliant and lead-free?
Yes, the 1N6276ARL4 uses a Pb-free external lead finish, fully compliant with RoHS Directive 2011/65/EU. Its axial leads are designed for soldering at 230°C for 10 seconds at 1/16 inch from the case, and the device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for through-hole assembly processes.
Does the 1N6276ARL4 have UL recognition for safety-critical applications?
Yes, the 1N6276ARL4 carries UL 497B recognition (File #116110, Category QVGV2) for isolated loop circuit protection. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown testing - confirming suitability for medical equipment, telecom interfaces, and other safety-regulated systems.
How does the 1N6276ARL4 differ from the 1N6276A variant?
The 1N6276ARL4 and 1N6276A share identical electrical specifications, package (Case 41A), and marking - differing only in packaging format: 1N6276ARL4 is supplied in 1500-unit tape-and-reel for automated assembly, whereas 1N6276A comes in 500-unit boxes for manual or low-volume use. Both are drop-in replacements electrically and mechanically.
What is the maximum steady-state power dissipation for the 1N6276ARL4?
The 1N6276ARL4 has a steady-state power dissipation rating of 5.0 W at lead temperature (TL) ≤ 75°C, with thermal resistance RJL = 20°C/W. Power must be derated linearly above 75°C - e.g., at TL = 100°C, allowable PD drops to 0 W - making it unsuitable for continuous forward conduction but optimal for transient-only duty cycles.
