Product details
Overview
MDA3KP13A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails and signal lines. It features a 13 V reverse standoff voltage (VWM), 14.4–15.9 V breakdown voltage (V(BR)), 21.5 V maximum clamping voltage at 139.4 A peak pulse current, and operates from −55 °C to +150 °C - used in industrial motor drives, telecom power supplies, and railway signaling interfaces.
For engineers reviewing the MDA3KP13A datasheet, MDA3KP13A pinout, MDA3KP13A application, or MDA3KP13A equivalent, key selection criteria include clamping performance under 10/1000 µs surge, standoff voltage margin relative to DC rail, thermal derating above 25 °C, and compliance with IEC61000-4-2/4-4/4-5 secondary lightning test levels.
Technical Context
The MDA3KP13A employs silicon avalanche diode technology optimized for fast response (<100 ps rise time) and high-energy absorption in unidirectional configuration. Its 3000 W peak pulse power rating is validated per 10/1000 µs waveform with ≤0.05% duty cycle, and it meets MIL-PRF-19500 screening options for high-reliability programs.
It delivers 5 µA maximum standby current at 13 V, supports 260 °C soldering per MIL-STD-750 Method 2026, and uses void-free UL94V-0 epoxy packaging with tin-lead or matte-tin terminations - polarity defined by dot marking and odd-numbered pins as cathodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 14.4–15.9 V @ 1 mA - ensures reliable avalanche initiation before system damage occurs |
| VC @ IPP | 21.5 V @ 139.4 A - limits downstream voltage stress during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - enables protection against IEC61000-4-5 Class 1–4 secondary lightning surges |
| ID @ VWM | ≤5 µA - minimizes leakage impact on low-power sensing or battery-backed circuits |
| TJ/TSTG | −55 °C to +150 °C - supports operation in harsh environments including engine compartments and outdoor base stations |
Pinout & Package
MDA3KP13A is housed in a surface-mount, void-free thermosetting epoxy package (UL94V-0) weighing ~5 g, with dimensions 21.03 × 6.86 × 8.64 mm (L × W × H). Pin 1 is marked by a dot; odd-numbered pins are cathodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line; conducts surge current to ground when V > V(BR) |
| Pin 2 | Anode of Channel 1 | Typically tied to system ground or low-impedance return path |
| Pin 3 | Cathode of Channel 2 | Enables dual-line protection (e.g., differential bus or redundant supply rail) |
| Pin 4 | Anode of Channel 2 | Shared or independent ground connection depending on layout isolation requirements |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional construction | Prevents reverse-bias leakage in DC-coupled power rails while enabling precise clamping threshold control |
| 3000 W peak pulse power | Withstands 139.4 A surge current at 10/1000 µs - exceeds IEC61000-4-5 Class 4 requirements with 42 Ω source impedance |
| MIL-PRF-19500 upscreening option | Supports high-reliability qualification for aerospace, defense, and rail applications via wafer lot traceability and 3σ ID screening |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement per J-STD-020B - simplifies SMT handling and reduces assembly cost |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | 600 W PPP rating, 13 V VWM, same unidirectional configuration but lower surge capacity | Not suitable for IEC61000-4-5 Class 3/4; limited to ESD/EFT and low-energy switching transients | Select SMBJ13A only where board space constraints preclude MDA3KP13A's larger footprint and surge demands are ≤600 W |
| SMCJ13A | 1500 W PPP rating, identical VWM and clamping, but half the peak pulse current (93.1 A vs. 139.4 A) | Meets IEC61000-4-5 Class 1–2 only with 42 Ω source; insufficient for Class 3/4 compliance | Choose SMCJ13A for cost-sensitive industrial controls where full 3000 W capability is not required |
Compared with SMBJ13A and SMCJ13A, the MDA3KP13A provides 2× and 1.5× higher peak pulse power respectively, enabling robust secondary lightning protection across all IEC61000-4-5 classes - critical for infrastructure-grade reliability where single-point failure is unacceptable.

FAQ
What is the clamping voltage of MDA3KP13A at its rated peak pulse current?
The MDA3KP13A has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPP) of 139.4 A under 10/1000 µs waveform conditions. This value is guaranteed per the manufacturer's electrical characteristics table and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is MDA3KP13A RoHS compliant?
Yes, MDA3KP13A is RoHS compliant, indicated by the "e3" suffix in its full part marking per Microsemi's nomenclature guide. The device uses annealed matte-tin plating on terminals and meets lead-free soldering requirements up to 260 °C for 10 seconds, aligning with IPC/JEDEC J-STD-020B Level 1 moisture sensitivity classification.
Can MDA3KP13A be used for bidirectional protection?
No, MDA3KP13A is unidirectional only. Its part number lacks the "C" suffix (e.g., MDA3KP13CA), which designates bidirectional variants. Using MDA3KP13A in AC or bipolar signal paths would result in forward conduction during negative half-cycles - select MDA3KP13CA instead for true bidirectional clamping behavior.
What is the standoff voltage margin between MDA3KP13A and a typical 12 V DC rail?
The MDA3KP13A has a 13 V reverse standoff voltage (VWM), providing a 1 V margin above a nominal 12 V DC rail. This margin accommodates normal operating ripple and tolerances while preventing premature conduction - consistent with Microsemi's recommendation that VWM be equal to or greater than the peak operating voltage of the protected line.
Does MDA3KP13A require derating at elevated ambient temperatures?
Yes, MDA3KP13A requires thermal derating above 25 °C ambient, as shown in Figure 3 of the datasheet. At 100 °C case temperature, its peak pulse power drops to approximately 65% of the 3000 W rating - meaning effective clamping capability decreases proportionally unless heatsinking or layout improvements compensate for junction temperature rise.
