Product details
Overview
MX15KP36A/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 36 V working standoff voltage (VWM), 40.0 V minimum breakdown voltage (V(BR)), 59.7 V maximum clamping voltage (VC) at 251 A peak pulse current, and 15,000 W peak pulse power rating at 10/1000 µs waveform - deployed in industrial AC/DC power supplies and telecom line interfaces.
For engineers reviewing the MX15KP36A/TR datasheet, MX15KP36A/TR pinout, MX15KP36A/TR application, or MX15KP36A/TR equivalent, key selection criteria include VWM ≥ system DC operating voltage, VC < protected IC's absolute maximum rating, IPP margin against expected surge threat level, and DO-204AR axial package compatibility with through-hole PCB layouts.
Technical Context
This device operates as a silicon avalanche diode with fast response (<5 ns rise time) and low dynamic impedance during clamping. Its unidirectional polarity enables DC-biased line protection without reverse leakage concerns above VWM, while its 20 °C/W junction-to-lead thermal resistance supports sustained surge dissipation when mounted per MIL-STD-750 soldering standards.
The MX15KP36A/TR is rated for –65 °C to +150 °C junction temperature and complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (lightning-induced surges with 2–42 Ω source impedance). Its 100% surge testing and 3σ lot screening on standby current ensure reliability in mission-critical industrial and telecom infrastructure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous DC or peak repetitive voltage applied without conduction; must exceed circuit's normal operating voltage. |
| V(BR) min | 40.0 V at 5 mA - Avalanche onset threshold; defines minimum voltage where clamping begins under standardized test current. |
| VC max | 59.7 V at 251 A (10/1000 µs) - Clamped voltage seen by downstream circuitry during worst-case surge; must stay below protected device's absolute max rating. |
| PPP | 15,000 W - Peak power handling capability at 10/1000 µs waveform; determines survivability against lightning-induced transients. |
| ID max | 10 µA at VWM - Leakage current at rated standoff voltage; ensures minimal power loss and no false triggering in standby. |
| IPP max | 251 A - Peak surge current the device can shunt without failure; directly correlates with IEC 61000-4-5 Class 3/4 compliance at 42 Ω source. |
| αV(BR) | 41 mV/°C - Temperature coefficient of breakdown voltage; used to calculate V(BR) derating over operating temperature range. |
Pinout & Package
MX15KP36A/TR uses the DO-204AR axial-lead package: void-free thermosetting epoxy body (UL94V-0), tin-lead or RoHS-compliant matte-tin plating, cathode indicated by band, weight ≈1.4 g, and mechanical dimensions per Figure 5-1 (LL: 27.95–38.1 mm, BD: 6.1–6.35 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage rail; completes current path during positive surge events. |
| Cathode | High-side surge input terminal | Connected to protected line; avalanche conduction initiates here when voltage exceeds V(BR); marked by band. |

IC Role / Device Role / Timing Role: TVS installed at connector entry point to shunt ESD events per IEC 61000-4-2 (±8 kV contact, ±15 kV air) before signals reach optocouplers or level shifters. Use Value: 10 µA max ID at 36 V ensures negligible loading on 24 V sensing circuits, while sub-5 ns response prevents logic upset during fast transients. |
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 SMAJ36A | Same VWM (36 V), lower PPP (400 W), DO-214AC package (SMD), 64.5 V VC at 6.5 A. | Targeted at board-level ESD/EFT only; insufficient for IEC 61000-4-5 Class 3/4 lightning protection. | Select when space-constrained SMD layout required and surge threat level is limited to IEC 61000-4-2/4-4. |
| ON Semiconductor 1.5KE36A | Same VWM (36 V), same DO-204AR package, 60.0 V VC at 250 A, but no MIL-PRF-19500 upscreening options. | Lacks high-reliability screening and lot traceability; not qualified for aerospace or defense programs requiring MIL spec compliance. | Select for cost-sensitive industrial applications where military-grade reliability is not mandated. |
Compared with MX15KP36A/TR, SMAJ36A offers surface-mount convenience but sacrifices >97% peak power capacity, while 1.5KE36A matches form-factor and basic electrical specs yet omits upscreening and statistical leakage control - making MX15KP36A/TR the sole choice for high-reliability, high-energy surge environments.

FAQ
What is the clamping voltage of the MX15KP36A/TR under a 251 A surge?
The MX15KP36A/TR has a maximum clamping voltage (VC) of 59.7 V when subjected to a 251 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions in Table 3-1 of the official Microchip datasheet DS00005222B and represents the upper limit of voltage imposed on protected circuitry during worst-case surge events. Designers must verify that this clamping level remains safely below the absolute maximum ratings of downstream components.
Is the MX15KP36A/TR RoHS compliant?
Yes, the MX15KP36A/TR is available in RoHS-compliant versions with annealed matte-tin plating, as confirmed in the Product Overview and Mechanical Packaging sections of Microchip's DS00005222B datasheet. The "TR" suffix denotes tape-and-reel packaging, which aligns with EIA-296 standards and supports automated assembly - and RoHS compliance applies to both bulk and TR variants unless otherwise specified in ordering codes.
Can the MX15KP36A/TR be used for bidirectional surge protection?
No, the MX15KP36A/TR is a unidirectional TVS diode, as indicated by its part number suffix "A" and explicit designation in Microchip's datasheet. Bidirectional variants in the same family use "CA" suffixes (e.g., MX15KP36CA). Using MX15KP36A/TR on AC lines or floating references without proper polarity orientation will result in unintended conduction or failure to clamp negative transients - always confirm polarity marking (cathode band) and circuit biasing before integration.
What is the thermal resistance specification for the MX15KP36A/TR?
The MX15KP36A/TR has a thermal resistance of 20 °C/W from junction to lead (RθJL) when mounted with 0.375 inch (10 mm) lead length from the body, per Table 1-1 in DS00005222B. This parameter is critical for estimating junction temperature rise during repeated surge events and confirms suitability for through-hole mounting on FR4 PCBs with adequate copper pour - unlike RθJA (80 °C/W), RθJL reflects direct heat transfer to the PCB traces via leads.
Does the MX15KP36A/TR meet IEC 61000-4-5 for lightning surge immunity?
Yes, the MX15KP36A/TR is explicitly rated for secondary lightning protection per IEC 61000-4-5 across multiple classes and source impedances: it supports Class 1–4 with 42 Ω source, Class 1–2 with 12 Ω, and Class 2 with 2 Ω, as detailed in the Applications/Benefits section of DS00005222B. Its 15,000 W peak pulse power and 251 A IPP capability enable compliance without external series impedance - provided PCB layout follows Microchip's recommended pad and trace guidelines.
