Product details
Overview
P6KE180AG 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 180 V breakdown voltage (VBR = 171–189 V), 246 V maximum clamping voltage (VC) at 2.4 A peak pulse current (IPP), and 600 W peak pulse power rating per 1 ms waveform - deployed in industrial power supplies and communication interfaces to protect downstream ICs from ESD and lightning-induced surges.
For engineers reviewing the P6KE180AG datasheet, pinout, applications, or equivalent options, key selection criteria include verified VRWM ≥ 154 V, clamping performance under IEC 61000-4-5 surge conditions, thermal derating above 50°C, and UL 497B recognition for isolated loop circuit protection.
Technical Context
The P6KE180AG operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its specified breakdown range (171–189 V at 1 mA test current). Its clamping action limits transient voltage to ≤246 V at 2.4 A peak pulse current, maintaining low leakage (<5 µA at 154 V) and fast response time (<1 ns).
Thermal design relies on junction-to-lead resistance of 20 °C/W and steady-state power dissipation of 5.0 W at 25°C lead temperature, derated linearly above 50°C. It meets UL 497B for isolated loop circuit protection and supports Pb-free soldering at 260°C for 10 seconds at 1/16″ from case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 171–189 V @ 1 mA - defines minimum voltage at which avalanche conduction begins; sets lower bound for working voltage selection. |
| Working Peak Reverse Voltage (VRWM) | 154 V - maximum continuous reverse operating voltage before significant leakage; must exceed system DC/peak AC rail. |
| Clamping Voltage (VC) | 246 V @ IPP = 2.4 A - actual voltage seen by protected circuit during worst-case 1 ms transient; determines safe margin for downstream components. |
| Peak Pulse Power (PPK) | 600 W @ 1 ms - energy-handling capability per non-repetitive surge; validated per Figure 4 waveform (tp = 1 ms, tr ≤ 10 µs). |
| Leakage Current (IR) | <5 µA @ 154 V - ensures minimal standby power loss and signal integrity in high-impedance circuits. |
| Response Time | <1 ns - enables suppression before transient propagates beyond PCB trace inductance; critical for protecting fast logic and analog inputs. |
| ESD Rating | Class 3 (>16 kV HBM) - qualifies for direct handling in automated assembly without additional ESD mitigation. |
Pinout & Package
Surmetic-40 axial-leaded plastic package (Case 017AA), cathode indicated by band. Leads are corrosion-resistant, readily solderable, rated for 260°C for 10 s at 1/16″ from case. Mounting position unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | High-side transient input | Connected to protected line (e.g., DC input, data line); polarity band identifies this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Validated for isolated loop circuit protection including strike voltage breakdown, endurance conditioning, and dielectric withstand - required for telecom and industrial safety compliance. |
| Temperature Coefficient of VBR | 0.108 %/°C - enables predictable voltage drift over −55°C to +150°C operating range; supports stable clamping in automotive under-hood environments. |
| Pb-Free Packaging | G-suffix denotes RoHS-compliant Surmetic-40 construction - eliminates lead contamination risk in reflow and wave soldering processes. |
| Surge Robustness | Rated for 100 A forward surge (8.3 ms half-sine) - withstands repetitive inrush events in AC/DC front-end designs without degradation. |
Applications
| Industrial Power Supply Protection | Telecom Line Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Surface-mount SMB package; same VRWM (154 V), slightly higher VC (259 V @ 2.3 A); lower IPP (2.3 A vs. 2.4 A). | Requires PCB redesign for SMD layout; better suited for high-density consumer electronics where axial leads are impractical. | Select when board space is constrained and automated pick-and-place is preferred over through-hole assembly. |
| 1.5KE180A | Same axial package but 1.5 kW rating; higher VC (264 V @ 5.7 A); larger case (DO-201AE vs. Surmetic-40); 10× higher IPP. | Over-specified for 600 W use cases; introduces unnecessary cost and thermal mass in compact industrial modules. | Choose only when legacy 1.5KE footprint compatibility is mandatory or surge threat level exceeds 600 W. |
Compared with SMBJ180A and 1.5KE180A, the P6KE180AG delivers optimal balance of axial-lead manufacturability, UL 497B certification, and precise 600 W clamping for mid-tier industrial systems - avoiding SMD placement complexity while remaining more compact and cost-effective than 1.5 kW alternatives.

FAQ
What is the maximum clamping voltage of the P6KE180AG under standard test conditions?
The P6KE180AG has a maximum clamping voltage (VC) of 246 V when subjected to its rated peak pulse current of 2.4 A with a 1 ms waveform (per Figure 4 in the datasheet). This value is measured at TA = 25°C and represents the upper limit of voltage imposed on the protected circuit during a transient event. The P6KE180AG maintains this clamping performance consistently across its qualified operating temperature range.
Does the P6KE180AG meet UL safety standards for circuit protection?
Yes, the P6KE180AG is UL Recognized under UL 497B (File #E210057) for isolated loop circuit protection. It has passed rigorous tests including strike voltage breakdown, endurance conditioning, temperature cycling, dielectric withstand, and discharge validation. This certification applies across the full P6KE6.8A–P6KE200A series and confirms suitability for safety-critical industrial and telecom applications where regulatory compliance is mandatory.
What does the "G" suffix in P6KE180AG signify?
The "G" suffix in P6KE180AG indicates a Pb-free (RoHS-compliant) version of the Surmetic-40 axial-leaded package. It uses lead-free terminations and conforms to JEDEC J-STD-020 moisture sensitivity level (MSL) requirements. The P6KE180AG retains identical electrical specifications, thermal characteristics, and mechanical dimensions as the non-Pb-free P6KE180A variant, enabling drop-in replacement in environmentally regulated manufacturing environments.
How does the P6KE180AG's thermal derating work above 50°C ambient?
The P6KE180AG's steady-state power dissipation (PD) is rated at 5.0 W at TL = 25°C and derates linearly at 50 mW/°C above TL = 50°C, reaching zero at TL = 150°C. Its junction-to-lead thermal resistance is fixed at 20 °C/W. For reliable operation, designers must ensure lead temperature remains within −55°C to +150°C and apply derating curves from Figures 2 and 5 in the official P6KE6.8A datasheet when estimating real-world surge handling at elevated temperatures.
Can the P6KE180AG be used in bidirectional protection configurations?
No - the P6KE180AG is strictly unidirectional and must be installed with correct polarity (cathode toward the protected line, anode to ground). For bidirectional transient suppression, ON Semiconductor offers the CA-suffixed variants (e.g., P6KE180CA), which integrate two opposing diodes in a single package. Using the P6KE180AG in reverse-biased orientation will not provide clamping and may result in catastrophic failure under positive transients.
