Product details
Overview
MX15KP60A/TR from Microchip Technology is a unidirectional axial-lead transient voltage suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 60 V working standoff voltage (VWM), 66.7 V minimum breakdown voltage (V(BR)), 97.3 V maximum clamping voltage (VC) at 154 A peak pulse current, and 15,000 W peak pulse power rating at 10/1000 µs waveform - deployed in industrial AC/DC front-ends and telecom line interfaces.
For engineers reviewing the MX15KP60A/TR datasheet, MX15KP60A/TR pinout, MX15KP60A/TR application, or MX15KP60A/TR equivalent, key selection criteria include clamping performance under IEC61000-4-5 Class 3 (42 Ω source), standoff margin relative to DC bus voltage, thermal resistance (RθJL = 20 °C/W), and RoHS-compliant tin-lead plating compatibility with wave soldering.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient overvoltages within nanoseconds. Its unidirectional polarity (cathode band marked) enables asymmetric protection on DC rails, and its DO-204AR axial package supports through-hole mounting with 1.4 g mass and UL94V-0 epoxy encapsulation.
It meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and secondary lightning immunity per IEC61000-4-5 across Classes 1–4 using 42 Ω, 12 Ω, and 2 Ω source impedances - with validated clamping at 97.3 V for 154 A pulses and <100 ps response time from 0 V to V(BR) min.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V DC - maximum continuous reverse voltage before leakage exceeds 10 µA; sets minimum operating margin above 48 V DC bus. |
| V(BR) min | 66.7 V at 5 mA - guaranteed avalanche initiation threshold; ensures reliable conduction onset during transients. |
| VC @ IPP | 97.3 V at 154 A (10/1000 µs) - peak clamped voltage seen by protected ICs; defines worst-case stress on downstream circuitry. |
| PPP | 15,000 W - peak power dissipation capability; enables survival of 4 kV/2 Ω lightning surges per IEC61000-4-5. |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; allows direct heatsinking via PCB copper pads without external heatsink. |
| ID @ VWM | 10 µA max - standby leakage at rated standoff; negligible loading on 48 V supply rails. |
| TJ range | –65 to +150 °C - operational junction temperature span; supports deployment in outdoor enclosures and industrial cabinets. |
Pinout & Package
MX15KP60A/TR uses the DO-204AR axial-lead package: void-free UL94V-0 epoxy body, tin-lead or RoHS matte-tin plating, cathode indicated by colored band, 1.4 g mass, and mechanical dimensions (mm): LL = 27.95–38.1, BL = 9.27–9.52, BD = 6.1–6.35, LD = 1.22–1.32.

|---|---|
Use Scenario: Secondary-side 48 V DC distribution in base station power systems exposed to induced RFI and switching transients from nearby relays or motors. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +48 V rail and chassis ground to clamp positive-going surges while blocking normal DC bias. Use Value: Limits transient voltage to ≤97.3 V, protecting downstream DC-DC controllers (e.g., LM5017) and PMICs from destructive overvoltage events. |
Use Scenario: Protection of Ethernet PHY interface circuits connected to outdoor cabling subject to lightning-induced surges per IEC61000-4-5. IC Role / Device Role / Timing Role: Front-end TVS on PSE-powered data lines, coordinated with common-mode chokes to divert differential-mode energy. Use Value: Clamps 154 A surges within 100 ps, maintaining signal integrity and preventing latch-up in Gigabit Ethernet transceivers (e.g., DP83867IR). |
| Automotive Body Control Module (BCM) Power Rail | Renewable Energy Inverter DC Link |
Use Scenario: 12 V/24 V battery-fed BCM modules subjected to load dump and ISO 7637-2 Pulse 5a transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power input, positioned upstream of LDO regulators and microcontrollers. Use Value: Absorbs 15,000 W peak energy without failure, enabling compliance with automotive EMC requirements while minimizing PCB area vs. multi-stage designs. |
Use Scenario: DC link protection in solar string inverters where PV array transients couple into 600–1000 V DC buses. IC Role / Device Role / Timing Role: Standoff-rated TVS on intermediate DC stage (e.g., post-boost, pre-inverter) to limit voltage overshoot during rapid MPPT transitions. Use Value: Provides 60 V VWM margin above nominal 48 V auxiliary control rail, ensuring stable operation during grid fault recovery sequences. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | Lower PPP (600 W), SMC package, 101 V VC @ 53.3 A - 3.7× lower surge capacity than MX15KP60A/TR. | Targeted at board-level ESD/EFT only; insufficient for IEC61000-4-5 Class 3 lightning. | Select SMBJ60A only for space-constrained consumer electronics where 15 kW surge immunity is not required. |
| 15KPA60A | Same 15 kW rating and DO-204AR package, but higher VC (102 V) and wider V(BR) tolerance (60–66.7 V vs. 66.7 V min). | Acceptable for general-purpose surge suppression but less precise clamping control in safety-critical systems. | Choose 15KPA60A if tighter V(BR) spec and guaranteed 66.7 V min onset are needed for predictable trip timing. |
Compared with SMBJ60A and 15KPA60A, MX15KP60A/TR delivers superior clamping precision (97.3 V max), guaranteed minimum breakdown (66.7 V), and full IEC61000-4-5 Class 3 compliance - making it optimal for industrial power systems requiring deterministic overvoltage protection.

FAQ
What is the clamping voltage of MX15KP60A/TR at its rated peak pulse current?
The MX15KP60A/TR has a maximum clamping voltage (VC) of 97.3 V when subjected to its rated peak pulse current of 154 A under the 10/1000 µs waveform. This value is measured per Figure 4-2 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is MX15KP60A/TR RoHS compliant and compatible with lead-free assembly processes?
Yes, MX15KP60A/TR is available in RoHS-compliant versions with annealed matte-tin plating that meets MIL-STD-750 Method 2026 solderability requirements. Its moisture sensitivity level is rated IPC/JEDEC J-STD-020F Level 1, eliminating the need for dry packing or baking prior to wave or reflow soldering.
Does MX15KP60A/TR meet IEC61000-4-5 for lightning surge immunity?
Yes, MX15KP60A/TR is certified for secondary lightning protection per IEC61000-4-5 across Classes 1–4 using 42 Ω, 12 Ω, and 2 Ω source impedances. For example, it supports Class 3 (42 Ω) up to 240 V VWM devices, and MX15KP60A/TR itself is validated for this class at its 60 V rating.
What is the thermal resistance specification for MX15KP60A/TR and how does it impact PCB layout?
MX15KP60A/TR has a junction-to-lead thermal resistance (RθJL) of 20 °C/W. This allows efficient heat transfer from the silicon die to the PCB leads, enabling reliable operation without external heatsinks when mounted on FR4 with 4 mm² copper pads and 1 mm wide traces - per JEDEC test conditions in Table 1-1.
How does the "TR" suffix in MX15KP60A/TR affect packaging and ordering?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, intended for automated pick-and-place assembly. MX15KP60A/TR is supplied in reels optimized for SMT production lines, with quantities and reel specifications available upon request from Aetrix Electronics or directly from Microchip.
