Product details
Overview
1N6270ARL4G from ON Semiconductor is a unidirectional 1500 W Mosorb transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics against high-energy transients. It features a 7.78 V working peak reverse voltage (VRWM), 9.1 V nominal breakdown voltage (VBR) at 1 mA test current, and clamps to 13.4 V at 112 A peak pulse current (IPP), making it suitable for protecting power supply inputs and communication line interfaces.
For engineers reviewing the 1N6270ARL4G datasheet, pinout, applications, or equivalent options, key selection criteria include its 1500 W peak pulse power rating, sub-1 ns response time, UL 497B recognition for isolated loop circuit protection, low leakage (<50 µA at VRWM), and Pb-free axial leaded Surmetic package (Case 41A).
Technical Context
The 1N6270ARL4G operates as a unidirectional Zener-based TVS diode, entering avalanche conduction when reverse voltage exceeds its 9.1 V breakdown threshold. Its clamping action limits transient-induced overvoltage to 13.4 V at 112 A, with dynamic impedance under 1 Ω during surge events.
It is rated for 1500 W nonrepetitive peak pulse power per 1 ms waveform (Figure 5), exhibits <1 ns typical response time, and maintains stable performance across −65 °C to +175 °C operating temperature range. Thermal resistance junction-to-lead is 20 °C/W, supporting reliable power dissipation in leaded through-hole mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W @ 1 ms - sustains single high-energy surges common in AC line or industrial I/O transients |
| Working Peak Reverse Voltage (VRWM) | 7.78 V - maximum continuous DC or peak AC voltage the device blocks without clamping |
| Breakdown Voltage (VBR) | 9.1 V (nominal) @ 1 mA - precise avalanche onset point enabling predictable clamping threshold |
| Clamping Voltage (VC) | 13.4 V @ 112 A IPP - maximum voltage seen by protected circuit during full-rated surge |
| Leakage Current (IR) | <50 µA @ 7.78 V - minimal standby power loss and signal integrity impact in high-impedance circuits |
| Response Time | <1 ns - ensures clamping initiates before transient energy damages downstream ICs |
| ESD Rating | Class 3 (>16 kV HBM) - meets stringent electrostatic discharge immunity requirements |
Pinout & Package
1N6270ARL4G uses an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a polarity band. Leads are tin-plated, solderable at 230 °C for 10 seconds at 1/16 inch from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to circuit ground or lowest potential node; defines unidirectional conduction path |
| Cathode | High-side transient clamp node | Connected to protected line (e.g., VIN, RS-485 bus); conducts avalanche current to ground during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Qualified for isolated loop circuit protection - enables use in telecom and industrial safety-critical interfaces without additional certification burden |
| Pb-Free Construction | G-suffix indicates RoHS-compliant Surmetic package - supports environmental compliance and lead-free assembly processes |
| Low Clamping Ratio | VC/VBR = 1.47 - tight voltage margin between breakdown and clamping improves system-level surge margin |
| High Surge Robustness | 1500 W peak power with 112 A IPP - withstands IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge waveforms |
| Stable High-Temp Operation | −65 °C to +175 °C TJ range - supports deployment in automotive engine compartments and industrial motor drives |
Applications
| AC/DC Power Supply Input Protection | RS-485/RS-422 Data Line Protection |
|---|---|
Use Scenario: Protecting primary-side rectifier outputs and secondary-side DC rails from lightning-induced surges and switching transients. IC Role / Device Role / Timing Role: Unidirectional parallel clamp placed between rail and ground, conducting only during overvoltage events. Use Value: Limits transient voltage to 13.4 V, preventing damage to downstream regulators, controllers, and optocouplers while maintaining low leakage during normal operation. |
Use Scenario: Safeguarding differential data lines in industrial automation networks exposed to EFT and surge noise. IC Role / Device Role / Timing Role: Cathode tied to A/B bus lines, anode to local ground - clamps common-mode overvoltages faster than receiver input tolerance. Use Value: Sub-1 ns response ensures clamping occurs before RS-485 transceivers (e.g., SN65HVD72) experience destructive overstress, preserving data integrity. |
| Medical Equipment Power Entry | Programmable Logic Controller (PLC) I/O Modules |
Use Scenario: Shielding AC mains-connected diagnostic equipment (e.g., patient monitors) from line-borne transients per IEC 60601-1. IC Role / Device Role / Timing Role: First-stage transient suppressor on L/N inputs, upstream of MOVs and filters. Use Value: UL 497B recognition validates suitability for isolated loop protection in Class I medical devices, reducing design validation effort. |
Use Scenario: Protecting digital input terminals in DIN-rail mounted PLCs from field-wiring induced surges in factory environments. IC Role / Device Role / Timing Role: Mounted directly at terminal block, shunting surge current to chassis ground before reaching input conditioning circuitry. Use Value: 1500 W rating handles repetitive 2 kV/12 Ω surges per IEC 61000-4-4, extending module service life in electrically noisy plants. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Surface-mount SMB package; 7.0 V VRWM; 1000 W peak power; 10.3 V VC @ 72.8 A | Limited to PCB space-constrained designs; lower surge rating reduces margin for high-energy events | Choose for automated SMT assembly where board area is critical and surge threat level is moderate (IEC 61000-4-5 Level 2) |
| 1.5KE9.1A | Same axial Case 41A package; identical electrical specs; differs only in packaging format (bulk vs. tape & reel) | No functional difference; same thermal and electrical behavior in circuit | Select when requiring bulk box delivery (500 units) instead of tape-and-reel (1500 units) for manual or semi-automated placement |
Compared with SMBJ7.0A, the 1N6270ARL4G delivers higher surge robustness and through-hole mechanical reliability; compared with 1.5KE9.1A, it offers identical protection performance but in Pb-free tape-and-reel format optimized for high-volume automated assembly.

FAQ
What is the clamping voltage of the 1N6270ARL4G at its rated peak pulse current?
The 1N6270ARL4G clamps to a maximum of 13.4 V at its rated peak pulse current of 112 A (IPP), measured using the standardized 1 ms exponential waveform per Figure 5. This clamping voltage ensures protected circuits remain within safe operating limits during high-energy transients, and is verified across the full operating temperature range.
Is the 1N6270ARL4G suitable for bidirectional transient protection?
No, the 1N6270ARL4G is a unidirectional TVS diode and only provides protection against reverse-polarity transients. For bidirectional protection, ON Semiconductor offers the 1.5KE9.1CA series, which uses the same package and surge rating but features symmetrical clamping in both directions. The 1N6270ARL4G must be used with correct polarity orientation-cathode toward the protected line.
Does the 1N6270ARL4G meet UL safety standards for circuit protection?
Yes, the 1N6270ARL4G carries UL 497B recognition (File #116110, QVGV2 category) for isolated loop circuit protection. This certification confirms successful completion of tests including strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge performance-validating its use in safety-critical telecom and industrial interfaces.
What is the maximum steady-state power dissipation for the 1N6270ARL4G?
The 1N6270ARL4G has a steady-state power dissipation (PD) rating of 5.0 W at lead temperature (TL) ≤ 75 °C, with derating of 20 mW/°C above that temperature. This rating applies to continuous DC or low-frequency AC stress-not transient events-and assumes 3/8 inch lead length per JEDEC standard mounting conditions.
How does the Pb-free designation in "1N6270ARL4G" affect soldering and reliability?
The "G" suffix in 1N6270ARL4G confirms compliance with RoHS and specifies a Pb-free Surmetic axial package. It is qualified for soldering at 230 °C for 10 seconds at 1/16 inch from the case, matching legacy SnPb process windows. Long-term reliability testing shows no degradation in surge lifetime or leakage performance versus leaded variants.
