Product details
Overview
P6KE16AG from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic-40 package, designed for parallel clamping of voltage transients on DC power rails and signal lines. It features 13.6 V working peak reverse voltage (VRWM), 22.5 V maximum clamping voltage at 27 A peak pulse current, and 600 W peak pulse power rating per 1 ms waveform - deployed in industrial power supplies and medical equipment input protection.
For engineers reviewing the P6KE16AG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin over operating voltage, clamping voltage vs. protected IC absolute maximum ratings, surge current capability under IEC 61000-4-5 waveforms, and Pb-free compliance for RoHS-constrained designs.
Technical Context
The P6KE16AG operates as a silicon avalanche diode with fast turn-on response (<1 ns) and low dynamic impedance during transient events. Its breakdown voltage is tightly specified at 15.2–16.8 V @ 1 mA test current, and it maintains stable clamping performance across −55°C to +150°C junction temperature range.
Thermal design relies on junction-to-lead resistance of 20°C/W and 5.0 W steady-state power dissipation at 25°C lead temperature, derating linearly above 50°C. The device meets UL 497B for isolated loop circuit protection and carries Class 3 ESD rating (>16 kV HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 13.6 V - minimum reverse standoff voltage before significant leakage; must exceed circuit's max continuous DC voltage |
| VBR @ IT=1 mA | 15.2–16.8 V - precise avalanche onset range; ensures predictable triggering under surge conditions |
| VC @ IPP=27 A | 22.5 V - maximum clamped voltage seen by protected circuit during 1 ms 27 A transient |
| IPP | 27 A - peak pulse current capability at rated clamping voltage; supports IEC 61000-4-5 Level 3 surges |
| PPK | 600 W - non-repetitive peak power handling per 1 ms pulse; defines energy absorption limit |
| Leakage @ VRWM | <5 µA - negligible standby current draw; avoids loading sensitive reference or bias networks |
| Response Time | <1 ns - enables suppression before most microcontroller I/O or analog front-end damage thresholds are exceeded |
Pinout & Package
Surmetic-40 axial-leaded plastic package (Case 017AA), cathode indicated by polarity band. Leads are solderable per J-STD-020, rated for 260°C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes clamping path during reverse transient |
| Cathode | High-side connection point | Connected to protected line (e.g., +12 V rail); blocks normal operation, conducts during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Validated for isolated loop circuit protection - satisfies safety certification requirements without additional external components |
| Pb-Free Construction | RoHS-compliant Surmetic-40 package - eliminates lead content while maintaining mechanical robustness and thermal performance |
| ESD Robustness | Class 3 HBM (>16 kV) - withstands handling and system-level ESD events without degradation |
| Stable Temperature Coefficient | 0.086 %/°C - minimal VBR drift over temperature; preserves clamping margin across full operating range |
Applications
| Industrial Power Supply Input Protection | Medical Equipment ESD Clamping |
|---|---|
Use Scenario: 24 V 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 upstream rectifier and bulk capacitor. Use Value: Limits transient voltage to ≤22.5 V, protecting 30 V-rated input MOSFETs and enabling compliance with IEC 61000-4-5 Level 3 (1 kV/2 Ω) | Use Scenario: Front-panel USB and RS-232 ports on diagnostic imaging console subject to operator ESD contact discharge. IC Role / Device Role / Timing Role: Standoff protection element on data line pairs, grounded via short trace to chassis to shunt ESD current away from PHY ICs. Use Value: Responds in <1 ns to divert >15 kV HBM pulses, preventing latch-up or gate oxide rupture in UART transceivers |
| Process Control Sensor Interface | Business Machine Power Rail Clamp |
Use Scenario: 4–20 mA current loop interface in factory automation sensor node powered from shared 24 V bus. IC Role / Device Role / Timing Role: Reverse-polarity and surge protector mounted directly at terminal block entry, referenced to local ground plane. Use Value: Blocks reverse connection up to 13.6 V and clamps induced lightning surges to 22.5 V, preserving 24 V supply integrity and ADC reference stability | Use Scenario: +12 V main rail in multifunction printer with motor drivers and high-current solenoids. IC Role / Device Role / Timing Role: Primary overvoltage clamp on bulk supply output, located adjacent to DC-DC converter output capacitor. Use Value: Absorbs 600 W surge energy from relay coil flyback, preventing brownout resets and ensuring uninterrupted print job execution |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Surface-mount SMB package; same VRWM (13.6 V) and VC (22.5 V), but lower IPP (27.3 A vs. 27 A) and 600 W rating | Requires PCB re-layout for SMD placement; better suited for automated assembly and space-constrained designs | Select when board real estate is limited and reflow compatibility is required over axial through-hole mounting |
| 1.5KE16A | Same axial package but higher peak power (1500 W); VRWM = 13.6 V, VC = 24.4 V @ 61.5 A - looser clamping tolerance | Higher energy handling suits AC mains input stages; less precise clamping makes it less ideal for low-voltage logic rail protection | Choose for higher-energy surge environments where tighter clamping is secondary to total energy absorption |
Compared with SMBJ16A and 1.5KE16A, the P6KE16AG delivers identical clamping performance in a cost-optimized axial package with UL 497B recognition - making it optimal for through-hole industrial power inputs where layout flexibility and safety certification are prioritized over footprint size or extreme energy rating.

FAQ
What is the maximum clamping voltage of the P6KE16AG under surge conditions?
The P6KE16AG has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current of 27 A per the 1 ms exponential waveform defined in Figure 4 of the datasheet. This value is guaranteed across temperature and represents the highest voltage the protected circuit will experience during a worst-case transient event that the P6KE16AG is rated to handle.
Does the P6KE16AG meet UL safety standards?
Yes, the P6KE16AG is UL Recognized under UL 497B (File #E210057, QVGQ2 category) for isolated loop circuit protection. This certification covers the entire P6KE6.8A–P6KE200A series and validates performance in strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge testing - confirming suitability for safety-critical industrial and medical applications.
Is the P6KE16AG compatible with lead-free soldering processes?
Yes, the "G" suffix in P6KE16AG explicitly denotes a Pb-free Surmetic-40 package. It is qualified for lead-free reflow and hand-soldering per J-STD-020, with maximum lead temperature rated at 260°C for 10 seconds at 1/16″ from the case - fully compliant with RoHS Directive 2011/65/EU and IPC-J-STD-001 requirements.
How does the P6KE16AG compare to bidirectional TVS diodes?
The P6KE16AG is unidirectional and intended for DC line protection where polarity is fixed - it blocks reverse voltage up to 13.6 V and clamps positive transients only. Bidirectional variants (e.g., P6KE16CA) would be required for AC or floating signal lines. Using P6KE16AG on AC paths risks forward conduction and failure; always verify polarity alignment before deployment.
What is the thermal resistance specification for the P6KE16AG?
The P6KE16AG has a junction-to-lead thermal resistance (RJL) of 20°C/W, measured under standard mounting conditions with 3/8″ lead length. This value enables accurate thermal modeling of power dissipation during repetitive surge events and informs derating curves in Figures 1, 2, and 5 of the ON Semiconductor datasheet for P6KE6.8A Series.
