Product details
Overview
MX15KP54CA/TR from Microchip Technology is a bidirectional axial-lead transient voltage suppressor (TVS) diode designed for high-energy surge protection in industrial power supplies and telecom infrastructure. It features a 54 V working standoff voltage (VWM), 60.0 V minimum breakdown voltage (V(BR)), 87.5 V maximum clamping voltage (VC) at 171 A peak pulse current, and 15,000 W peak pulse power rating at 10/1000 µs waveform.
For engineers reviewing the MX15KP54CA/TR datasheet, MX15KP54CA/TR pinout, MX15KP54CA/TR application, or MX15KP54CA/TR equivalent, this device is evaluated for secondary lightning protection per IEC 61000-4-5 (2 Ω source impedance, Class 4), ESD immunity per IEC 61000-4-2, and EFT suppression per IEC 61000-4-4 in AC/DC front-end and DC bus interfaces.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient overvoltages before they damage downstream circuitry. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating signal/power lines, with <5 ns response time and <100 ps theoretical turn-on delay from 0 V to V(BR) min.
It is rated for continuous operation from –65 °C to +150 °C junction temperature, features 20 °C/W thermal resistance (junction-to-lead), and is qualified to MIL-PRF-19500 upscreening standards for enhanced reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 54 V DC - Maximum continuous reverse voltage before leakage exceeds 10 µA; sets minimum operating margin above system nominal voltage. |
| V(BR) min | 60.0 V at 5 mA - Guaranteed avalanche initiation threshold; ensures predictable turn-on during transients. |
| VC max | 87.5 V at 171 A (10/1000 µs) - Peak clamped voltage seen by protected circuit; defines worst-case stress on downstream ICs. |
| PPP | 15,000 W - Peak power dissipation capability; supports single-event surges up to 171 A without failure. |
| ID max | 10 µA at VWM - Low standby leakage; minimizes power loss and avoids false triggering in high-impedance bias networks. |
| TJ range | –65 °C to +150 °C - Wide operational temperature envelope suitable for outdoor enclosures and uncooled industrial cabinets. |
| RθJL | 20 °C/W - Thermal resistance from junction to lead; enables reliable heat transfer to PCB copper when mounted with 10 mm lead length. |
Pinout & Package
MX15KP54CA/TR uses the DO-204AR (Axial Lead) package: void-free UL94V-0 epoxy body, tin-lead or RoHS-compliant matte-tin plating, cathode band omitted due to bidirectional configuration, and ~1.4 g mass. Leads are 0.048–0.052 inch diameter, body length 1.100–1.500 inch, body diameter 0.240–0.250 inch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient current entry point (bidirectional) | Accepts positive or negative surge polarity; no polarity marking required for bidirectional operation. |
| Cathode (Lead 2) | Transient current exit point (bidirectional) | Completes low-impedance path to ground or return rail during either polarity event; symmetric with Anode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines, differential buses, or floating DC rails without polarity constraints. |
| 100% surge tested | Each unit validated at rated 15,000 W pulse, ensuring field reliability without batch sampling uncertainty. |
| MIL-PRF-19500 upscreening option | Available with wafer/lot traceability, 3σ ID screening, and moisture level 1 (no dry pack required), supporting aerospace-grade BOM continuity. |
| IEC 61000-4-5 Class 4 compliance (2 Ω) | Validated for secondary lightning protection in long-line telecom and utility metering applications with 2 Ω source impedance. |
| RoHS-compliant plating | Meets environmental regulations without compromising solderability or thermal performance (MIL-STD-750, method 2026). |
Applications
| AC Power Input Protection | Telecom Line Interface |
|---|---|
Use Scenario: AC mains input stage of industrial PLC power supply exposed to utility switching transients and nearby lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed across bridge rectifier output or AC line terminals. Use Value: Limits transient voltage to ≤87.5 V during 171 A events, protecting downstream bulk capacitors and controller ICs rated for 100 V max. |
Use Scenario: T1/E1 line interface card in central office equipment subjected to induced RFI and longitudinal surges. IC Role / Device Role / Timing Role: Bidirectional shunt protector across transformer secondary or line driver outputs. Use Value: Clamps both polarities equally, preserving signal integrity while meeting IEC 61000-4-5 Class 4 (2 Ω) requirements for telecom infrastructure. |
| DC Bus Surge Suppression | Motor Drive Control Board |
Use Scenario: 48 V DC distribution bus in factory automation cabinet experiencing inductive kickback from solenoid switching. IC Role / Device Role / Timing Role: Parallel-connected TVS across bus rails to absorb repetitive 15,000 W pulses. Use Value: Withstands >1000 surge events at rated power due to robust silicon die and low RθJL (20 °C/W), extending board service life. |
Use Scenario: Gate driver supply rail in 3-phase inverter where MOSFET switching induces fast dv/dt transients. IC Role / Device Role / Timing Role: Fast-response (<5 ns) clamp protecting isolated gate drivers and bootstrap capacitors. Use Value: Sub-100 ps turn-on latency prevents voltage overshoot beyond 87.5 V, avoiding driver latch-up or bootstrap capacitor overvoltage failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ54A | Unidirectional, 54 V VWM, 87.1 V VC @ 152 A, 400 W PPP, SMA package | Lower power rating; suited for PCB-level point-of-load protection, not primary AC/DC surge handling | Select for space-constrained designs requiring surface-mount footprint and lower-cost alternatives where 400 W suffices. |
| ON Semiconductor 1.5KE54A | Unidirectional, 54 V VWM, 87.1 V VC @ 152 A, 1500 W PPP, DO-201 package | Medium-power rating; appropriate for secondary protection stages or lower-energy industrial controls | Choose when legacy DO-201 mounting is required and peak surge energy does not exceed 1500 W. |
Compared with MX15KP54CA/TR, SMAJ54A and 1.5KE54A offer smaller footprints and lower cost but deliver only 400 W and 1500 W peak pulse power respectively-insufficient for primary IEC 61000-4-5 Class 4 (2 Ω) protection where 15,000 W capability is mandatory.

FAQ
What is the clamping voltage of MX15KP54CA/TR under standard test conditions?
The MX15KP54CA/TR has a maximum clamping voltage (VC) of 87.5 V when subjected to a 10/1000 µs surge waveform at its rated peak pulse current of 171 A. This value is measured across the device terminals during transient conduction and defines the upper voltage limit imposed on protected circuitry during surge events.
Is MX15KP54CA/TR unidirectional or bidirectional?
MX15KP54CA/TR is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative polarity transients without requiring polarity-specific placement. This makes it ideal for AC line protection, differential signaling, or floating DC bus applications where voltage reversal is possible.
Does MX15KP54CA/TR meet IEC 61000-4-5 Class 4 requirements?
Yes, MX15KP54CA/TR is validated for IEC 61000-4-5 Class 4 secondary lightning protection when tested with a 2 Ω source impedance. The device's 15,000 W peak pulse power rating and 87.5 V clamping voltage ensure compliance under the full Class 4 test profile defined in the standard.
What is the thermal resistance specification for MX15KP54CA/TR?
MX15KP54CA/TR has a thermal resistance of 20 °C/W from junction to lead (RθJL), measured at 0.375 inch (10 mm) from the body. This low value enables effective heat dissipation into PCB copper traces or chassis mounts, supporting repeated surge events without thermal runaway.
Can MX15KP54CA/TR be used in RoHS-compliant designs?
Yes, MX15KP54CA/TR is available in RoHS-compliant versions with annealed matte-tin plating, fully compliant with Directive 2011/65/EU. The device meets solderability requirements per MIL-STD-750, method 2026, and requires no dry pack due to IPC/JEDEC J-STD-020F Level 1 moisture sensitivity.
