Product details
Overview
P6KE120A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a 102V reverse standoff voltage (VRWM), 114V minimum breakdown voltage (VBR), 165V maximum clamping voltage (VC) at 3.6A peak pulse current (IPP), and DO-15 package with glass-passivated junction - used in industrial power supply input stages to absorb lightning-induced surges.
For engineers reviewing the P6KE120A-T datasheet, P6KE120A-T pinout, P6KE120A-T application, or P6KE120A-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, peak pulse current capability under IEC 61000-4-5 surge waveforms, thermal derating above +25°C ambient, and unidirectional polarity compatibility with grounded-cathode rail protection schemes.
Technical Context
This TVS operates as a voltage-clamped crowbar device triggered by avalanche breakdown when transient voltage exceeds its VBR. Its 1.0ms 600W peak pulse rating follows the standard 10/1000μs waveform definition per REA, with fast sub-nanosecond response time enabling effective suppression of ESD and surge events before downstream components are stressed.
Thermal design relies on low RθJA (75°C/W) and RθJL (15°C/W) values, allowing 5.0W steady-state dissipation at TL = +75°C on 40mm² copper land. The DO-15 package's molded plastic body meets UL 94V-0 flammability rating and supports lead-free reflow soldering per MIL-STD-202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (10/1000μs waveform; defines maximum transient energy absorption without failure) |
| Reverse Standoff Voltage | 102V (maximum continuous DC or RMS voltage applied without significant leakage) |
| Breakdown Voltage | 114V min @ 1.0mA IT (avalanche onset threshold; ensures reliable triggering before VC is reached) |
| Clamping Voltage | 165V max @ 3.6A IPP (voltage seen by protected circuit during worst-case surge; determines safe margin for downstream ICs) |
| Package | DO-15 (axial-leaded, through-hole mount; 25.4mm body length, 5.5–7.62mm diameter; compatible with legacy PCB layouts) |
| Operating Temp | −55°C to +175°C (enables use in under-hood automotive, industrial motor drives, and outdoor telecom equipment) |
| Leakage Current | ≤5.0μA @ 102V VR (low standby power loss; avoids false triggering or battery drain in always-on systems) |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon junction, cathode-banded end marking. Body length 25.4mm, diameter 5.5–7.62mm, lead diameter 0.686–0.889mm, lead spacing 2.6–3.6mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes conduction loop during avalanche clamp event |
| Cathode | High-side connection point | Connected to protected line (e.g., +12V rail); polarity-sensitive for unidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| 600W Peak Pulse Rating | Supports IEC 61000-4-5 Level 4 (4kV line-to-line, 2kV line-to-ground) surge immunity testing |
| Glass Passivated Junction | Enhances reliability against moisture ingress and surface contamination in humid environments |
| Fast Response Time | Sub-nanosecond turn-on enables clamping before transient propagates to sensitive logic or analog circuits |
| RoHS Compliant & Halogen-Free | Meets EU Directive 2011/65/EU and Diodes' "Green" material definitions for eco-conscious manufacturing |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) Power Rails |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power module exposed to load dump and ISO 7637-2 transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND to clamp positive-going surges while blocking reverse voltage. Use Value: 165V clamping voltage provides >30% margin above 120V load dump peak, preventing damage to upstream rectifier and downstream DC-DC controller. | Use Scenario: 12V battery-fed microcontroller power domain in door module subjected to jump-start and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage protector on MCU VDD rail, coordinated with fuse and LC filter. Use Value: 114V breakdown ensures stable operation during normal 14V alternator regulation while responding within <1ns to 100V+ spikes. |
| Telecom Remote Radio Unit (RRU) DC Feeder Line | Renewable Energy Inverter DC Link Monitoring Circuit |
Use Scenario: Outdoor base station powered via 48V PoE-like feeder cable subject to induced lightning surges. IC Role / Device Role / Timing Role: First-stage transient suppressor on DC input before DC-DC conversion and Ethernet PHY isolation. Use Value: 600W rating handles 10/1000μs surges up to 3.6A without degradation, maintaining integrity across 100,000+ surge events. | Use Scenario: Voltage sensing network on 400V DC link of solar inverter, where precision resistive dividers interface with ADC. IC Role / Device Role / Timing Role: Low-leakage (≤5μA) TVS shunting transient energy away from high-impedance divider nodes. Use Value: 5.0μA IR at 102V prevents measurement offset drift and preserves ADC accuracy during long-term operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ120A-T | Same VRWM (102V), lower PPK (600W), but SMC package (surface-mount, smaller footprint) | Requires PCB redesign for SMD placement; better suited for space-constrained consumer electronics vs. industrial through-hole layouts | Select SMBJ120A-T only if board real estate is critical and thermal management via copper pour is feasible |
| 1.5KE120A-T | Higher PPK (1500W), same DO-15 package, but larger junction capacitance and slower response due to higher junction area | Better for high-energy surges (e.g., AC mains coupling), less optimal for fast ESD pulses near digital interfaces | Choose 1.5KE120A-T when system-level testing requires >1kW surge handling, accepting trade-offs in speed and layout sensitivity |
Compared with SMBJ120A-T and 1.5KE120A-T, P6KE120A-T delivers optimal balance of proven through-hole reliability, precise 165V clamping, and thermal performance in legacy industrial designs - making it preferred where mechanical robustness and serviceability outweigh miniaturization needs.

FAQ
Is P6KE120A-T RoHS compliant and halogen-free?
Yes. P6KE120A-T meets EU Directive 2011/65/EU (RoHS 2) with all applicable exemptions applied, and conforms to Diodes Incorporated's "Green" material definition - meaning it is both lead-free and halogen-free, with antimony-free flame retardants per their published specifications.
What is the maximum operating temperature for P6KE120A-T?
P6KE120A-T has an operating and storage temperature range of −55°C to +175°C. Its junction-to-ambient thermal resistance is 75°C/W, and derating begins above +25°C ambient - full 600W pulse capability is maintained only at TA ≤ +25°C, with linear reduction per the pulse derating curve in DS21502.
Can P6KE120A-T be used in bidirectional configurations?
No. P6KE120A-T is unidirectional (denoted by 'A' suffix). For bidirectional operation, the correct part is P6KE120CA-T, which lacks cathode band marking and clamps symmetrically for AC or floating-rail applications - using P6KE120A-T in bidirectional circuits risks catastrophic failure during negative transients.
How does P6KE120A-T compare to SMAJ120A in terms of surge handling?
P6KE120A-T offers 600W peak pulse power in DO-15 package with 165V clamping at 3.6A, while SMAJ120A provides 400W in SMA package with 165V clamping at 2.4A. The P6KE version sustains higher surge current and benefits from superior thermal mass and lead-to-board heat transfer - critical for repeated surge exposure in industrial environments.
