Product details
Overview
P6KE160A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 136V reverse standoff voltage (VRWM), 152V minimum breakdown voltage (VBR), 219V maximum clamping voltage (VC) at 2.7A peak pulse current (IPP), and DO-15 package with glass-passivated junction-used in industrial power supplies and automotive ECU input protection.
For engineers reviewing the P6KE160A-T datasheet, P6KE160A-T pinout, P6KE160A-T application, or P6KE160A-T equivalent, key selection criteria include clamping performance under 1.0ms 600W pulses, thermal derating above +25°C ambient, unidirectional polarity marking (cathode band), and compliance with IATF 16949 manufacturing for automotive-qualified variants.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR (152–168V), it avalanches to divert surge current away from downstream circuitry. Its 219V VC at IPP = 2.7A ensures protected ICs see limited overvoltage during standardized 8/20μs or 1.0ms pulses.
Constructed with glass-passivated silicon die in a DO-15 molded plastic case (UL 94V-0), it delivers fast response time (<1.0ns), low leakage (<5.0μA @ VRWM), and stable clamping across -55°C to +175°C operating range-enabling use in harsh-environment power entry stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive pulse-defines maximum single-event surge energy absorption capability |
| Reverse Standoff Voltage | 136V (VRWM)-maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage | 152–168V (VBR @ 1.0mA)-avalanche onset range determining clamping threshold precision |
| Clamping Voltage | 219V max @ 2.7A IPP-voltage seen by protected load during full-rated surge event |
| Package | DO-15-axial-leaded, through-hole mountable package with 0.4g mass and 75°C/W junction-to-ambient thermal resistance |
| Operating Temp | -55°C to +175°C-supports under-hood automotive and industrial power converter deployments |
| Leakage Current | ≤5.0μA @ VRWM-ensures minimal standby power loss in high-impedance bias networks |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon junction in molded plastic body (UL 94V-0), cathode indicated by band on unidirectional variant. Leads are solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection in unidirectional configuration | Connected to ground or return path; current flows anode-to-cathode during clamping |
| Cathode | High-side connection; marked with band | Connected to protected line; avalanche conduction initiates when cathode voltage exceeds VBR relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| 600W Peak Pulse Rating | Enables robust protection against IEC 61000-4-5 Level 4 surges (4kV/2Ω) on 24V–48V systems |
| Glass-Passivated Junction | Improves long-term reliability and moisture resistance vs. epoxy-passivated alternatives |
| Fast Response Time | <1.0ns reaction to transients-prevents voltage overshoot before clamping engages |
| RoHS-Compliant Lead Finish | Lead-free plating meets EU Directive 2011/65/EU with full exemption documentation |
| Unidirectional Polarity | Cathode-band marking eliminates orientation errors during manual or automated assembly |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) Power Rail |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Shunt TVS device clamping voltage spikes before they reach upstream rectifier and downstream DC-DC controller ICs. Use Value: Limits transient voltage to ≤219V, preventing damage to 36V-rated input capacitors and 40V MOSFETs in primary-side regulation. | Use Scenario: 12V battery-fed power rail in BCM controlling door locks, lighting, and window motors. IC Role / Device Role / Timing Role: Primary overvoltage clamp during ISO 7637-2 Pulse 5a (load dump up to 60V for 400ms). Use Value: Absorbs 600W surge energy without degradation, maintaining system uptime during vehicle alternator regulation failure. |
| Telecom Remote Radio Unit (RRU) DC Feed Line | Renewable Energy Inverter DC Link Protection |
Use Scenario: -48V DC power feed to outdoor RRU mounted on cellular tower, subject to lightning-induced surges. IC Role / Device Role / Timing Role: First-line transient suppressor on DC input before isolation and DC-DC conversion stages. Use Value: Clamps induced surges to 219V within nanoseconds, protecting sensitive RF front-end ICs rated for ≤24V absolute maximum. | Use Scenario: 600V DC link between PV array and grid-tie inverter, requiring protection against switching transients and grid faults. IC Role / Device Role / Timing Role: Secondary clamping device supplementing MOV-based primary protection on high-voltage DC bus. Use Value: Provides precise 136V standoff and fast response where MOVs exhibit higher clamping tolerance and slower reaction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-T | Same VRWM (136V) and VC (219V), but SMB package (surface-mount); 600W rating retained | Requires PCB re-layout for SMT assembly; lower thermal resistance (RθJA = 40°C/W) improves power handling in compact designs | Select for space-constrained, high-volume production where automated placement is preferred |
| 1.5KE160A | Legacy 1.5kW series; same DO-15 package but higher 1.5kW rating and 225V VC @ 6.7A IPP | Over-spec'd for 600W requirements; larger junction capacitance may affect high-speed signal integrity | Choose only if legacy design reuse or higher surge margin is mandatory; not drop-in due to different surge profile |
Compared with SMBJ160A-T and 1.5KE160A, P6KE160A-T offers optimal balance of through-hole manufacturability, thermal performance in ambient air, and cost-efficiency for mid-power industrial and automotive protection-without over-engineering or footprint compromise.

FAQ
Is P6KE160A-T still in active production?
No-P6KE160A-T is officially obsolete per Diodes Incorporated's DS21502 Rev. 20-4 (August 2024). It is discontinued and no longer manufactured. Aetrix Electronics maintains limited legacy stock for last-time buy and repair programs, with full traceability and RoHS documentation.
What is the difference between P6KE160A and P6KE160CA?
P6KE160A is unidirectional (cathode-banded), while P6KE160CA is bidirectional (no polarity marking, symmetrical clamping). Both share identical VRWM (136V), VBR (152–168V), and VC (219V), but P6KE160CA supports AC line protection where polarity reversal occurs.
Can P6KE160A-T be used in automotive AEC-Q101 qualified designs?
While P6KE160A-T itself is not AEC-Q101 certified, Diodes offers automotive-grade variants (e.g., P6KE160AHE3_A/H) manufactured in IATF 16949 facilities and PPAP-capable. Standard P6KE160A-T is suitable for non-safety-critical automotive applications where qualification is not mandated.
What is the maximum steady-state power dissipation for P6KE160A-T?
At TL = +75°C with 9.5mm lead length mounted on 40mm² copper land, PD = 5.0W. Derating follows Fig. 5: power drops linearly to zero at +200°C lead temperature, with RθJL = 15°C/W and RθJA = 75°C/W typical values.
