Product details
Overview
P6KE170AG from ON Semiconductor is a unidirectional 600 W transient voltage suppressor (TVS) diode in axial-leaded Surmetic−40 package, designed for parallel clamping of high-energy transients. It features a 145 V working peak reverse voltage (VRWM), 234 V maximum clamping voltage at 2.6 A peak pulse current (IPP), and <1 ns response time-used to protect power supplies, industrial controls, and medical equipment input stages from ESD and lightning-induced surges.
For engineers reviewing the P6KE170AG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥ system DC bus voltage, VC margin below IC absolute maximum ratings, UL 497B recognition for isolated loop protection, and Pb-free axial-lead compatibility with wave-soldering processes at 230°C.
Technical Context
The P6KE170AG operates as a silicon avalanche diode, entering breakdown when reverse voltage exceeds its 162–179 V VBR range (measured at 1 mA IT). Its clamping action limits transient voltage to ≤234 V at 2.6 A IPP under 1 ms 10/1000 µs waveform, with thermal resistance of 20°C/W junction-to-lead enabling 5.0 W steady-state dissipation at TL ≤ 75°C.
It exhibits low leakage (<5 µA @ VRWM), 0.108 %/°C VBR temperature coefficient, and ESD robustness >16 kV per Human Body Model. Polarity is marked by cathode band; mounting position is unrestricted, and lead soldering tolerance is specified at 230°C for 10 seconds at 1/16″ from case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 145 V - Maximum continuous reverse operating voltage before clamping begins; must exceed circuit's peak DC or AC rectified voltage. |
| VBR (min/typ/max) | 162 / 170.5 / 179 V @ 1 mA - Breakdown onset range; defines minimum voltage at which device reliably enters avalanche conduction. |
| VC @ IPP | 234 V @ 2.6 A - Clamped voltage during 1 ms transient; determines maximum stress imposed on downstream components. |
| PPK | 600 W - Peak pulse power handling capability; validates surge immunity against IEC 61000-4-5 Level 4 (4 kV/2 Ω) events. |
| IR @ VRWM | <5 µA - Reverse leakage current; ensures minimal standby power loss and signal integrity in high-impedance sensing paths. |
| Response Time | <1 ns - Time from transient onset to clamping initiation; critical for protecting fast logic and analog front-ends. |
| UL Recognition | UL 497B QVGV2 - Certified for isolated loop circuit protection; satisfies safety compliance for telecom and industrial interfaces. |
Pinout & Package
Package: Surmetic−40 axial-leaded plastic case (Case 017AA), void-free thermosetting material, corrosion-resistant finish, cathode indicated by polarity band. Lead length standard; mounting position unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to circuit ground or lowest potential node; completes current path during reverse-biased clamping. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., DC input rail); polarity band identifies this terminal for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Withstands 1 ms 10/1000 µs surges up to 2.6 A without degradation-validates use in mains-connected power supply inputs. |
| UL 497B certification | Qualified for isolated loop protection in telecom and process control systems-reduces need for additional safety validation. |
| Pb-free axial package (G suffix) | Complies with RoHS and JEDEC J-STD-020 reflow profiles; compatible with automated wave soldering at 230°C for 10 s. |
| ESD rating >16 kV HBM | Survives handling and board-level ESD events without parameter shift-enables use in exposed front-panel interfaces. |
| 0.108 %/°C VBR tempco | Ensures stable clamping threshold across −55°C to +175°C operating range-critical for automotive under-hood and industrial ambient extremes. |
Applications
| Industrial Power Supply Input Protection | Medical Equipment ESD Shielding |
|---|---|

Use Value: Enables single-device compliance with UL 497B for isolated data ports-eliminates need for multi-stage protection circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170A | Surface-mount SMB package; same VRWM (145 V) and VC (234 V), but lower PPK (600 W vs. P6KE170AG's 600 W), identical IT and IPP. | Requires PCB re-layout for SMT assembly; unsuitable for through-hole or high-reliability axial-leaded designs. | Select when automated SMT production and board space constraints outweigh axial-lead serviceability needs. |
| 1.5KE170A | Same axial package but higher PPK (1500 W); VRWM = 145 V, VC = 234 V @ 6.4 A IPP; larger case size (Case 017AB). | Offers higher surge margin for utility-grade metering or outdoor power electronics; requires more board real estate and lead-forming. | Choose for applications demanding >600 W surge headroom where physical size and lead spacing allow. |
Compared with SMBJ170A and 1.5KE170A, the P6KE170AG delivers identical clamping performance in a cost-optimized, UL-recognized axial package ideal for legacy through-hole manufacturing and field-serviceable designs-without requiring layout changes or sacrificing safety certification.

FAQ
What is the maximum clamping voltage of the P6KE170AG under standard surge conditions?
The P6KE170AG has a maximum clamping voltage (VC) of 234 V when subjected to its rated peak pulse current (IPP) of 2.6 A under a 1 ms 10/1000 µs waveform. This value is measured per Figure 4 in the official datasheet and represents the upper limit of voltage seen by protected circuitry during a defined transient event. The P6KE170AG maintains this clamping performance across its full operating temperature range.
Does the P6KE170AG meet UL safety standards for isolated loop protection?
Yes, the P6KE170AG carries UL 497B recognition under file #E210057 and classification QVGV2 for isolated loop circuit protection. This certification covers surge withstand, dielectric voltage-withstand, endurance conditioning, and strike voltage breakdown testing-making the P6KE170AG suitable for telecom interfaces, industrial fieldbus isolators, and medical data acquisition systems requiring regulatory-compliant transient suppression.
What does the "G" suffix in P6KE170AG signify?
The "G" suffix in P6KE170AG indicates a Pb-free (RoHS-compliant) version of the device, packaged in the same Surmetic−40 axial-leaded Case 017AA. It meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements and supports wave soldering at 230°C for 10 seconds at 1/16″ from the case. The P6KE170AG retains identical electrical specifications-including VRWM, VBR, VC, and PPK-as its non-Pb-free counterpart P6KE170A.
Can the P6KE170AG be used in bidirectional signal lines?
No, the P6KE170AG is a unidirectional TVS diode and must only be used in DC-biased or ground-referenced applications. For bidirectional protection-such as AC lines or differential data buses-ON Semiconductor offers the P6KE170CA variant (with "CA" suffix), which provides symmetrical clamping in both polarities. Using the P6KE170AG on bidirectional signals risks forward conduction and failure during negative half-cycles.
What is the thermal resistance and steady-state power rating of the P6KE170AG?
The P6KE170AG has a junction-to-lead thermal resistance (RJL) of 20°C/W and a steady-state power dissipation (PD) rating of 5.0 W at lead temperature (TL) ≤ 75°C with 3/8″ lead length. Derating is required above 75°C at 50 mW/°C. This thermal profile supports reliable operation in enclosed industrial enclosures and power supply heatsink-mounted configurations where lead temperature can be controlled.
