Product details
Overview
P6KE100ARLG from onsemi is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic-40 package, designed for parallel clamping of high-energy transients. It features 100 V breakdown voltage (VBR = 95–105 V @ IT = 1 A), 137 V maximum clamping voltage (VC) at 4.4 A peak pulse current (IPP), and 600 W peak power dissipation (1 ms). It protects power supplies, industrial controls, and medical equipment against ESD and lightning-induced surges.
For engineers reviewing the P6KE100ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (VRWM = 85.5 V), clamping performance under 1 ms surge, Pb-free tape-and-reel packaging (4000/reel), UL 497B recognition for isolated loop protection, and <1 ns response time.
Technical Context
The P6KE100ARLG operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its specified VBR range. Its clamping action limits transient voltage to ≤137 V at IPP = 4.4 A, ensuring downstream circuit protection without conduction during normal operation below VRWM = 85.5 V.
It exhibits low leakage (<5 µA @ VRWM), a temperature coefficient of 0.106 %/°C for VBR, and thermal resistance RJL = 20 °C/W. Designed for leaded through-hole mounting, it supports steady-state power dissipation of 5.0 W at TL ≤ 25°C, derating linearly above 50°C.

Applications
| Industrial Power Supply Protection | Medical Equipment Surge Suppression |
|---|---|
Use Scenario: DC input stage of DIN-rail mounted 24 V/48 V industrial power supply exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed across input terminals to clamp transients before they reach upstream rectifier and downstream DC-DC controller. Use Value: Limits transient voltage to ≤137 V, preventing damage to MOSFETs and PWM controllers while maintaining system uptime under EN 61000-4-5 Level 3 stress. | Use Scenario: Patient-connected auxiliary power rail in diagnostic imaging equipment requiring compliance with IEC 60601-1 surge immunity. IC Role / Device Role / Timing Role: Primary overvoltage protector on isolated 5 V or 12 V auxiliary supply feeding analog front-end sensors. Use Value: UL 497B recognition validates suitability for medical isolated loops; <1 ns response ensures clamping precedes ADC saturation or op-amp latch-up. |
| Communication System Interface Protection | Numerical Control Input Protection |
Use Scenario: RS-485 transceiver power rail in factory-floor PLC communication modules subject to cable-induced surges. IC Role / Device Role / Timing Role: Standoff TVS on VCC line of isolated RS-485 transceiver, coordinated with series impedance for IEC 61000-4-5 compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Surface-mount SMB package; same VRWM (85.5 V), slightly lower VC (136 V @ 4.5 A), 600 W rating | Requires re-layout for SMT; better high-frequency transient response due to lower parasitic inductance | Select for space-constrained designs where automated assembly and reduced board area outweigh through-hole reliability preferences |
| 1.5KE100A | Same axial package but higher peak power (1500 W); VRWM = 85.5 V, VC = 137 V @ 11 A | Higher surge margin for infrequent but extreme events (e.g., outdoor telecom cabinets); larger physical size and thermal mass | Select when legacy 1.5 kW surge standards apply or where long-term reliability under repeated marginal surges is prioritized over cost and footprint |
Compared with SMBJ100A and 1.5KE100A, the P6KE100ARLG offers optimal balance of axial-leaded robustness, UL 497B certification for isolated systems, and cost-effective 600 W protection - making it preferred for industrial control and medical auxiliary rails where regulatory compliance and mechanical durability are critical.

FAQ
What is the working peak reverse voltage (VRWM) specification for P6KE100ARLG?
The P6KE100ARLG has a working peak reverse voltage (VRWM) of 85.5 V. This value defines the maximum continuous DC or peak AC voltage the device can block in normal operation without entering avalanche conduction. It must be selected ≥ the circuit's maximum steady-state operating voltage to ensure reliable standoff behavior - for example, it is appropriate for 72–80 VDC industrial bus lines.
Does P6KE100ARLG meet UL safety standards for surge protection?
Yes, the P6KE100ARLG is UL 497B recognized (File #E210057, QVGQ2 category) for isolated loop circuit protection. This certification confirms successful completion of strike voltage breakdown, endurance conditioning, temperature, dielectric withstand, and discharge testing - validating its use in safety-critical applications such as medical auxiliary supplies and industrial control interfaces.
What is the clamping voltage of P6KE100ARLG under surge conditions?
The P6KE100ARLG clamps to a maximum of 137 V when subjected to its rated peak pulse current of 4.4 A (1 ms exponential waveform per Figure 4). This VC value is the upper bound of voltage seen by downstream components during transient events, directly determining whether connected ICs (e.g., microcontrollers or gate drivers) remain within absolute maximum ratings.
Is P6KE100ARLG compatible with lead-free soldering processes?
Yes, the "RLG" suffix in P6KE100ARLG explicitly denotes a Pb-free package compliant with RoHS Directive 2011/65/EU. It supports standard lead-free reflow profiles with maximum lead temperature of 260°C at 1/16″ from the case for 10 seconds, as verified in the onsemi Soldering and Mounting Techniques Reference Manual.
How does the response time of P6KE100ARLG affect circuit protection performance?
The P6KE100ARLG has a typical response time of <1 ns, enabling it to begin clamping before most fast-rising transients (e.g., ESD or inductive spikes) propagate into sensitive circuitry. This rapid turn-on minimizes voltage overshoot - especially critical when protecting high-speed logic or precision analog stages - provided layout keeps lead lengths short and the device is placed adjacent to the protected node.
