Product details
Overview
P6KE7.5AG 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 600 W peak pulse power (1 ms), 6.4 V working peak reverse voltage (VRWM), 11.3 V clamping voltage at 53 A peak pulse current (VC @ IPP), and <1 ns response time - deployed in power supplies and industrial control systems to protect downstream ICs and regulators.
For engineers reviewing the P6KE7.5AG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin over DC bus voltage, VC/IPP trade-off for system-level surge immunity, thermal derating above 50°C ambient, and UL 497B certification for isolated loop protection compliance.
Technical Context
The P6KE7.5AG operates as a silicon avalanche diode with precise breakdown voltage (VBR = 7.13–7.88 V @ IT = 10 mA), enabling predictable clamping onset. Its unidirectional polarity requires cathode-to-rail connection for positive transient suppression, and its low leakage (<500 µA @ VRWM) ensures minimal standby power loss in always-on circuits.
Thermal design relies on junction-to-lead resistance (RJL = 20 °C/W) and steady-state power dissipation (PD = 5.0 W @ TL ≤ 25°C), with linear derating to 50 mW/°C above TL = 50°C. The device 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 |
|---|---|
| Peak Pulse Power | 600 W @ 1 ms - withstands IEC 61000-4-5 Level 4 surges without failure |
| Working Peak Reverse Voltage | 6.4 V - sets maximum continuous DC/AC peak voltage before clamping activates |
| Clamping Voltage | 11.3 V @ 53 A IPP - limits protected circuit voltage during worst-case transient |
| Breakdown Voltage | 7.13–7.88 V @ 10 mA - defines sharp avalanche onset threshold for repeatable protection |
| Leakage Current | <500 µA @ 6.4 V - avoids loading low-power rails or battery-backed circuits |
| Response Time | <1 ns - enables suppression before fast-edge ESD or lightning-induced transients propagate |
| ESD Rating | Class 3 (>16 kV HBM) - exceeds IEC 61000-4-2 Level 4 for system-level ESD robustness |

Applications
| Industrial Power Supply Protection | Medical Equipment Input Stage |
|---|---|
Use Scenario: 24 V DC input stage of programmable logic controller exposed to inductive load switching and field wiring surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +24 V rail and chassis ground to clamp transients before they reach DC-DC converters and microcontrollers. Use Value: 11.3 V clamping prevents latch-up or damage to 3.3 V/5 V logic supply ICs; 600 W rating handles repetitive 10/1000 µs surges per IEC 61000-4-4. | Use Scenario: Patient-connected monitoring device with isolated analog front-end requiring certified surge protection on auxiliary power inputs. IC Role / Device Role / Timing Role: UL 497B-recognized TVS on isolated 5 V bias rail to meet IEC 60601-1 creepage/clearance and surge immunity requirements. Use Value: Enables single-device compliance with medical safety standards - avoids redesign for secondary protection or reinforced isolation. |
| Communication System Line Interface | Business Machine Power Entry |
Use Scenario: RS-485 transceiver power pins in outdoor base station equipment subject to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Cathode tied to VCC, anode to ground - clamps positive-going transients on local 3.3 V supply feeding transceivers. Use Value: Sub-1 ns response ensures clamping occurs before transceiver ESD structures fail; 53 A IPP rating covers 4 kV direct lightning coupling events. | Use Scenario: AC-DC adapter output stage in multifunction printer where motor startup causes repeated 100 V spikes on 12 V rail. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing repetitive 600 W pulses without degradation, protecting motor driver FET gate drivers and MCU reset circuitry. Use Value: 5.0 W steady-state rating and 20 °C/W thermal resistance enable reliable operation under continuous thermal stress from frequent motor cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Surface-mount SMB package; 7.0 V VRWM; 12.5 V VC @ 48.2 A; lower 600 W rating same but smaller footprint | Requires PCB rework for SMT layout; better suited for space-constrained consumer electronics vs. industrial axial-lead assemblies | Select when board space is limited and automated assembly is preferred over through-hole mounting |
| P6KE7.5A | Identical electrical specs and package; leaded version without Pb-free designation; RoHS non-compliant | Acceptable only in legacy industrial systems where Pb-free compliance is not mandated by regulation or customer requirement | Choose only if Pb-free sourcing is not required and existing inventory or cost favors non-Pb-free variant |
Compared with SMBJ7.0A, P6KE7.5AG offers axial-leaded mechanical robustness and UL 497B certification for isolated loops, while P6KE7.5A provides identical performance without RoHS compliance - making P6KE7.5AG the default choice for new industrial, medical, and telecom designs requiring safety recognition and environmental compliance.

FAQ
What is the clamping voltage of the P6KE7.5AG and how does it relate to system protection?
The P6KE7.5AG has a maximum clamping voltage (VC) of 11.3 V at 53 A peak pulse current (IPP). This value defines the highest voltage that will appear across the protected circuit during a transient event. For example, when used on a 5 V rail, this clamping level ensures downstream components rated for 12 V absolute maximum survive - provided series impedance limits peak current to ≤53 A. The P6KE7.5AG's low VC/VBR ratio (1.59) reflects optimized avalanche characteristics for minimal overvoltage stress.
Does the P6KE7.5AG meet UL 497B, and what does that certification cover?
Yes, the P6KE7.5AG is UL 497B recognized (File #E210057, QVGQ2 category) for isolated loop circuit protection. This certification validates performance in strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge testing - confirming suitability for telecom line cards, PoE injectors, and other applications requiring safety-agency-approved surge suppression on isolated interfaces. The P6KE7.5AG's UL listing applies directly; no additional qualification is needed for compliant system design.
How does the thermal derating of the P6KE7.5AG affect its steady-state power handling?
The P6KE7.5AG dissipates 5.0 W continuously at lead temperature (TL) ≤25°C, with linear derating of 50 mW/°C above TL = 50°C. At TL = 75°C, its usable steady-state power drops to 3.75 W. This derating is critical in enclosed power supplies or high-density industrial modules where lead temperature rises due to ambient heat and adjacent components. Engineers must calculate actual TL using RJL = 20 °C/W and ensure margins exist between measured TL and 150°C max junction temperature.
Can the P6KE7.5AG be used in bidirectional protection configurations?
No - the P6KE7.5AG is strictly unidirectional and must be installed with cathode toward the protected voltage rail. Bidirectional protection requires a separate part number (e.g., P6KE7.5CA) with symmetrical breakdown in both polarities. Using P6KE7.5AG in reverse orientation risks permanent damage during negative transients, as its forward voltage (VF ≤ 3.5 V @ 50 A) offers no clamping capability below −3.5 V. Always verify polarity marking (cathode band) during placement.
What is the significance of the "G" suffix in P6KE7.5AG?
The "G" suffix in P6KE7.5AG explicitly denotes a Pb-free (RoHS-compliant) Surmetic-40 package. It confirms compliance with EU RoHS Directive 2011/65/EU and J-STD-609 moisture sensitivity level (MSL) requirements. This distinguishes it from the non-Pb-free P6KE7.5A variant. The P6KE7.5AG supports standard lead-free reflow profiles up to 260°C for 10 seconds at 1/16″ from case - matching IPC/JEDEC J-STD-020 specifications for SnAgCu soldering.
