Product details
Overview
P6KE16ARL from ON Semiconductor is a unidirectional 600 W transient voltage suppressor (TVS) diode in axial-leaded Surmetic-40 package, designed for parallel clamping protection of DC power rails and signal lines. It features a 13.6 V working peak reverse voltage (VRWM), 16 V nominal breakdown voltage (VBR) at 1 mA test current, 22.5 V maximum clamping voltage (VC) at 27 A peak pulse current, and sub-1 ns response time - deployed in industrial power supplies and medical equipment input stages.
For engineers reviewing the P6KE16ARL datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin over operating voltage, VC vs. protected IC's absolute maximum rating, surge current capability under IEC 61000-4-5 waveform, and thermal derating above 25°C ambient.
Technical Context
The P6KE16ARL operates as a silicon avalanche diode with sharp reverse-breakdown knee and low dynamic impedance during transient events. Its clamping action begins at VRWM = 13.6 V and fully engages by VBR = 16 V (min 15.2 V, max 16.8 V), limiting voltage to ≤22.5 V at IPP = 27 A under 1 ms 10/1000 µs waveform per Figure 4.
It exhibits <5 µA leakage at VRWM, 0.086 %/°C temperature coefficient of VBR, and UL 497B recognition for isolated loop circuit protection. Thermal resistance junction-to-lead is 20 °C/W, enabling 5.0 W steady-state dissipation at TL ≤ 25°C with 3/8″ lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 13.6 V - Maximum continuous reverse voltage before significant leakage; must exceed system DC rail or signal peak. |
| VBR @ IT=1 mA | 15.2–16.8 V - Breakdown range defining turn-on threshold; ensures reliable conduction before protected device overstress. |
| VC @ IPP=27 A | 22.5 V - Clamped voltage during 1 ms surge; must stay below downstream IC's absolute max rating. |
| IPP | 27 A - Peak pulse current capacity under standard 10/1000 µs waveform; defines surge energy handling (600 W). |
| Leakage @ VRWM | <5 µA - Negligible standby power loss and minimal impact on high-impedance bias networks. |
| Response Time | <1 ns - Enables suppression of fast transients (e.g., ESD, relay bounce) before propagation into sensitive circuitry. |
| Package | Surmetic-40 axial lead (Case 017AA) - Through-hole mounting with cathode band; compatible with wave soldering at 260°C for 10 s. |
Pinout & Package
Surmetic-40 axial-leaded package (Case 017AA): cylindrical black epoxy body, 8.38–8.89 mm length (A), 3.30–3.68 mm diameter (B), 0.94–1.09 mm lead diameter (D), 25.4–31.75 mm lead length (K). Cathode indicated by single silver or white band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or lowest potential point in protected circuit; completes clamping path during reverse surge. |
| Cathode | High-side transient input | Connected to line being protected (e.g., +12 V rail); avalanche conduction occurs when voltage exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV, 2 Ω source) without failure when properly mounted. |
| UL 497B recognition | Validated for isolated loop protection in telecom and industrial interfaces - meets dielectric withstand and endurance requirements. |
| ESD Class 3 (>16 kV HBM) | Withstands human-body-model discharges common in handling and board-level integration without parameter shift. |
| Low temperature coefficient (0.086 %/°C) | Ensures stable VBR across −55°C to +150°C operating range - critical for automotive and outdoor equipment. |
| Pb-free option (P6KE16ARLG) | RoHS-compliant variant available with identical electrical specs and soldering profile (260°C, 10 s). |
Applications
| Industrial Power Supply Input Protection | Medical Equipment ESD Shielding |

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 SMB package (vs. axial P6KE16ARL); same VRWM (13.6 V), slightly lower VC (23.2 V @ 25.1 A). | Requires PCB re-layout; better suited for high-density consumer electronics where through-hole is impractical. | Select SMBJ16A when board space is constrained and automated SMT assembly is used. |
| 1.5KE16A | Same axial package but higher peak power (1500 W); VRWM = 13.6 V, VC = 24.4 V @ 61.5 A - larger junction area. | Over-specified for 600 W needs; introduces higher junction capacitance (~150 pF vs. ~50 pF), potentially affecting high-speed signal lines. | Select 1.5KE16A only when legacy 1.5 kW surge testing (e.g., MIL-STD-1275) applies and layout permits. |
Compared with SMBJ16A and 1.5KE16A, the P6KE16ARL delivers optimal balance of proven axial reliability, 600 W surge margin, low clamping voltage, and cost-effective tape-and-reel packaging - making it ideal for industrial power entry designs where manual or selective soldering is standard.

FAQ
What is the maximum clamping voltage of the P6KE16ARL under surge conditions?
The P6KE16ARL has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current of 27 A under the standard 1 ms 10/1000 µs waveform. This value is guaranteed across temperature and represents the upper limit of voltage seen by downstream circuitry during transient events - critical for ensuring compatibility with 24 V system ICs rated to 28 V absolute maximum.
Does the P6KE16ARL meet UL safety standards for circuit protection?
Yes, the P6KE16ARL carries UL 497B recognition (File #E210057, QVGQ2 category) for isolated loop circuit protection. This certification covers dielectric withstand, endurance conditioning, temperature stability, and discharge performance - confirming suitability for safety-critical telecom, industrial, and medical applications where regulatory compliance is mandatory.
How does the P6KE16ARL differ from the P6KE16A or P6KE16AG variants?
The P6KE16ARL is identical electrically to P6KE16A and P6KE16AG but supplied in 4000-piece tape-and-reel format (vs. 1000-unit box for A/G variants). The "RL" suffix denotes reel packaging; "G" indicates Pb-free construction. All share identical VRWM (13.6 V), VBR (15.2–16.8 V), and VC (22.5 V), with P6KE16ARLG being the Pb-free tape-and-reel version.
Can the P6KE16ARL be used in bidirectional protection circuits?
No - the P6KE16ARL is strictly unidirectional and must be installed with correct polarity (cathode toward the protected line). For bidirectional surge suppression, ON Semiconductor offers the P6KE16CA series. Using P6KE16ARL in reverse-biased AC applications risks catastrophic failure due to lack of forward conduction path during negative half-cycles.
What is the thermal derating behavior of the P6KE16ARL above 25°C ambient?
The P6KE16ARL's steady-state power dissipation derates linearly above 25°C ambient: 50 mW/°C reduction from its 5.0 W rating at TL ≤ 25°C. At 75°C ambient, usable PD drops to 4.0 W. Pulse power remains 600 W up to TL = 25°C but requires derating per Figure 2 - e.g., 70% of peak power at TL = 75°C - to avoid junction overheating and parameter drift.
