Product details
Overview
P6KE36ARLG from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic−40 package, designed for parallel clamping of high-energy transients. It features 36 V working peak reverse voltage (VRWM), 49.9 V maximum clamping voltage at 12 A peak pulse current, 600 W peak pulse power rating, and <1 ns response time-used to protect power supplies, industrial controls, and medical equipment inputs against ESD and lightning-induced surges.
For engineers reviewing the P6KE36ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥ circuit operating voltage, VC margin relative to IC absolute maximum ratings, UL 497B certification for isolated loop protection, and Pb-free tape-and-reel packaging for automated assembly.
Technical Context
The P6KE36ARLG operates as a silicon avalanche diode with precisely controlled breakdown characteristics, triggered when reverse voltage exceeds its 34.2–37.8 V VBR range at 1 mA test current. Its clamping action limits transient-induced overvoltage to ≤49.9 V under 12 A 10/1000 µs waveform, enabling robust protection without crowbar behavior.
Thermal design relies on junction-to-lead thermal resistance of 20 °C/W and steady-state power dissipation derated from 5.0 W at TL ≤ 75 °C. The device exhibits low leakage (<5 µA at VRWM) and a temperature coefficient of 0.099 %/°C for VBR stability across −55 to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 30.8 V - maximum continuous reverse operating voltage before clamping begins |
| VBR @ IT=1 mA | 34.2–37.8 V - precise avalanche onset range ensuring predictable turn-on threshold |
| VC @ IPP=12 A | 49.9 V - clamped voltage during 10/1000 µs surge, defining protected circuit's worst-case overvoltage |

| Response Time | <1 ns - enables suppression before sensitive downstream components experience overvoltage stress |
| Leakage Current | <5 µA @ 30.8 V - negligible standby power loss and minimal impact on high-impedance signal paths |

|---|---|
Use Scenario: DC input stage of programmable logic controller (PLC) power module exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed across input terminals to clamp positive-going surges before they reach bulk capacitor and regulator ICs. Use Value: Limits transient voltage to 49.9 V, preventing overvoltage failure of 36 V-rated input capacitors and 40 V-max LDOs while maintaining 30.8 V nominal operation. | Use Scenario: Analog sensor interface in patient-monitoring device where ECG leads connect to front-end amplifier. IC Role / Device Role / Timing Role: Low-capacitance TVS on differential signal pair to suppress ESD without distorting sub-mV biopotential waveforms. Use Value: Sub-1 ns response ensures clamping occurs before amplifier input stages saturate; <5 µA leakage avoids DC offset errors in high-gain instrumentation paths. |
| Telecom Isolated Loop Interface | Process Control Fieldbus Node Protection |
Use Scenario: 4–20 mA current loop transmitter connected to central control system via long cable runs susceptible to induced lightning surges. IC Role / Device Role / Timing Role: UL 497B-certified TVS installed at loop entry point to absorb common-mode transients while preserving loop integrity. Use Value: Certified compliance ensures system-level safety approval; 30.8 V VRWM matches typical loop supply headroom, avoiding false triggering during normal operation. | Use Scenario: PROFIBUS DP slave node mounted in factory floor cabinet with shared ground and adjacent motor drives. IC Role / Device Role / Timing Role: Bidirectional protection not required-unidirectional P6KE36ARLG clamps positive transients on VCC rail caused by nearby contactor switching. Use Value: 600 W rating withstands repetitive 100 A surge currents from nearby 480 VAC motor starters; axial package allows through-hole mounting on ruggedized PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Surface-mount SMB package; 36 V VRWM; 58.1 V VC @ 10.3 A; same 600 W rating | Requires PCB redesign for SMT vs axial through-hole; lower profile but higher thermal resistance (RθJL = 35 °C/W) | Select SMBJ36A only when board space constraints prohibit axial components and thermal management supports SMT layout. |
| 1.5KE36A | Same axial package; identical VRWM and VC specs; 1500 W peak power rating (higher surge capacity) | Higher cost and larger physical size; may require mechanical rework due to increased lead spacing and body length | Choose 1.5KE36A when legacy designs demand higher surge margin beyond IEC 61000-4-5 Level 4 requirements. |
Compared with SMBJ36A and 1.5KE36A, the P6KE36ARLG offers optimal balance of proven axial reliability, UL 497B certification, Pb-free tape-and-reel automation readiness, and cost-effective 600 W surge handling for industrial and medical power rail protection.

FAQ
What is the clamping voltage of P6KE36ARLG at its rated peak pulse current?
The P6KE36ARLG has a maximum clamping voltage (VC) of 49.9 V when subjected to its rated peak pulse current of 12 A under the standard 10/1000 µs waveform. This value is measured per Figure 4 in the official ON Semiconductor datasheet and defines the upper voltage limit imposed on protected circuits during surge events. Maintaining VC below downstream IC absolute maximum ratings is critical for reliable system-level protection using the P6KE36ARLG.
Does P6KE36ARLG meet UL safety standards for isolated loop protection?
Yes, the P6KE36ARLG carries UL 497B recognition under file #E210057 for protector classification (QVGV2), covering strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge testing. This certification applies specifically to the P6KE6.8A–P6KE200A series and validates its use in telecom and industrial isolated loop interfaces where safety-critical transient suppression is mandated. The P6KE36ARLG's UL listing is documented in the February 2007 Rev. 8 datasheet.
What is the meaning of the 'RLG' suffix in P6KE36ARLG?
The 'RLG' suffix in P6KE36ARLG indicates an axial-leaded, Pb-free device supplied in tape-and-reel packaging (4000 units per reel). The 'R' denotes tape-and-reel format, 'L' specifies axial lead configuration, and 'G' confirms compliance with RoHS Directive 2011/65/EU. This packaging enables automated pick-and-place assembly while meeting environmental regulations-distinct from the 'A' (bulk box) or 'AG' (Pb-free bulk) variants. All electrical specifications remain identical across suffixes.
How does the temperature coefficient affect P6KE36ARLG's breakdown voltage stability?
The P6KE36ARLG has a maximum temperature coefficient of 0.099 %/°C for its breakdown voltage (VBR), meaning VBR increases by up to 0.099% per degree Celsius rise in junction temperature. Over the full −55 to +175 °C operating range, this results in approximately ±12% VBR shift relative to 25 °C nominal. Designers must account for this drift when selecting VRWM margin-e.g., a 30.8 V VRWM part may exhibit ~34.5 V VBR at 125 °C, ensuring safe operation without premature clamping in high-temperature environments using the P6KE36ARLG.
Can P6KE36ARLG be used in bidirectional transient protection applications?
No, the P6KE36ARLG is a unidirectional TVS diode intended only for clamping positive-going transients on DC-biased lines. Its cathode-anode polarity is fixed, and it does not conduct in forward bias beyond typical diode drop (~3.5 V). For bidirectional protection (e.g., AC lines or data buses), ON Semiconductor specifies separate P6KE36CA devices. Using P6KE36ARLG in reverse-biased configurations risks permanent damage, as it lacks symmetrical avalanche characteristics-always verify polarity alignment in schematic and layout for the P6KE36ARLG.
