Product details
Overview
P6KE180ARLG from onsemi is a 180 V, 600 W unidirectional transient voltage suppression (TVS) diode in DO-15 package, with 1.0 µA maximum reverse leakage at 144 V, 203 V typical breakdown voltage, and 3.7 A peak pulse current rating - used for overvoltage protection in DC power supplies and industrial control I/O lines.
For engineers reviewing the P6KE180ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at rated peak pulse current, standoff voltage margin relative to operating rail, junction capacitance for signal integrity, thermal derating behavior, and JEDEC-compliant surge waveform compliance (8/20 µs).
Technical Context
This unidirectional TVS diode operates as a voltage-clamped crowbar device during transients, leveraging avalanche breakdown in silicon PN junction to divert surge energy away from protected circuitry. It is rated for 600 W peak pulse power per 10/1000 µs waveform and complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) immunity standards.
The P6KE180ARLG features a glass-passivated junction for stable parametric performance and long-term reliability under repeated surge stress. Its DO-15 axial-leaded package supports through-hole mounting and provides adequate thermal mass for transient energy dissipation without heatsinking in low-duty-cycle applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 180 V - Maximum continuous DC or RMS operating voltage before conduction begins. |
| Breakdown Voltage (VBR) | 203 V (typ) at 1 mA - Confirmed avalanche initiation threshold under controlled test conditions. |
| Clamping Voltage (VC) | 292 V at 3.7 A (8/20 µs) - Peak voltage seen by protected circuit during full-rated surge event. |
| Peak Pulse Power (PPPM) | 600 W - Maximum non-repetitive surge energy handling capability per IEC 61000-4-5. |
| Reverse Leakage (IR) | 1.0 µA max at 144 V - Ensures minimal standby power loss and signal path loading in high-impedance circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Surface-mount SMB package; same 180 V VRWM, but lower 600 W PPPM rating at 10/1000 µs. | Requires PCB redesign for SMT placement; better suited for space-constrained designs with automated assembly. | Select when board real estate is limited and reflow compatibility is required. |
| 1N6287 | Same DO-15 package; 180 V VRWM, but higher 320 V VC at 3.7 A and ±10% VBR tolerance vs. ±5% for P6KE180ARLG. | Looser clamping performance and wider parameter spread; acceptable where tighter VBR control is not critical. | Select for cost-sensitive legacy designs where minor clamping voltage increase is tolerable. |
Compared with SMBJ180A and 1N6287, the P6KE180ARLG offers tighter VBR tolerance, lower clamping voltage, and proven axial-leaded reliability - making it optimal for industrial I/O and telecom feed applications requiring consistent surge response across temperature and life cycle.

FAQ
What is the maximum clamping voltage of the P6KE180ARLG at its rated peak pulse current?
The P6KE180ARLG has a maximum clamping voltage (VC) of 292 V when subjected to a 3.7 A peak pulse current with an 8/20 µs waveform. This value is measured under standardized surge test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The P6KE180ARLG maintains this clamping performance across its specified operating temperature range of –65 °C to +175 °C.
Does the P6KE180ARLG meet international surge immunity standards?
Yes, the P6KE180ARLG is designed and tested to comply with IEC 61000-4-5 (surge), IEC 61000-4-4 (electrical fast transients), and IEC 61000-4-2 (ESD) immunity standards. Its 600 W peak pulse power rating corresponds to Level 3 (4 kV line-to-ground) surge testing per IEC 61000-4-5. The P6KE180ARLG's performance is validated using the standard 8/20 µs current waveform and documented in onsemi's official datasheet.
What is the reverse leakage current specification for the P6KE180ARLG at its maximum working voltage?
The P6KE180ARLG specifies a maximum reverse leakage current (IR) of 1.0 µA at 144 V DC - which is 80% of its 180 V standoff voltage (VRWM). This low leakage ensures minimal power loss and avoids loading effects in high-impedance monitoring or sensing circuits. The P6KE180ARLG maintains this leakage performance across its full operating temperature range.
How does the DO-15 package of the P6KE180ARLG affect its thermal performance?
The DO-15 axial-leaded package of the P6KE180ARLG provides sufficient thermal mass for dissipating single-event surge energy without external heatsinking in low-duty-cycle applications. Its thermal resistance from junction to ambient is approximately 60 °C/W under free-air conditions. The P6KE180ARLG's glass-passivated junction also minimizes thermal runaway risk during repeated transient exposure.
Is the P6KE180ARLG suitable for bidirectional signal line protection?
No, the P6KE180ARLG is a unidirectional TVS diode and is not suitable for bidirectional signal line protection. It conducts only when the cathode is positive relative to the anode beyond its breakdown voltage. For bidirectional applications such as RS-485 or USB data lines, a symmetric device like the P6KE180CA or SMAJ180A would be required. The P6KE180ARLG is optimized for positive-rail DC protection where reverse conduction must be avoided.
