Product details
Overview
MXDA3KP13A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. 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 AC/DC front-end surge protection circuits.
For engineers reviewing the MXDA3KP13A datasheet, MXDA3KP13A pinout, MXDA3KP13A application, or MXDA3KP13A equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω source impedance, 10/1000 µs surge rating, RoHS-compliant e3 matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MXDA3KP13A is a single-channel unidirectional TVS diode optimized for fast clamping of high-energy transients. Its sub-100 ps response time enables effective suppression of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and induced switching surges. The device uses silicon avalanche technology with thermoset epoxy packaging rated UL94V-0.
It delivers 3000 W peak pulse power at 10/1000 µs waveform with 5% tolerance on VWM and full lot traceability. Standby leakage is ≤5 µA at 13 V, and forward surge capability reaches 200 A at 8.3 ms half-sine, supporting robust front-end protection in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous operating voltage before clamping begins; matches 12 V nominal DC bus systems. |
| V(BR) min–max | 14.4–15.9 V - Confirmed avalanche onset range at 1 mA test current; ensures reliable turn-on margin above VWM. |
| VC @ IPP | 21.5 V - Clamping voltage at 139.4 A peak pulse; limits downstream voltage stress during 10/1000 µs surges. |
| IPP | 139.4 A - Peak impulse current supported at rated clamping voltage; defines surge energy handling per IEC61000-4-5. |
| ID @ VWM | ≤5 µA - Low standby leakage at rated standoff voltage; minimizes power loss in always-on protection circuits. |
| TJ/TSTG | –55 to +150 °C - Extended junction temperature range supports operation in industrial enclosures and automotive under-hood zones. |
Pinout & Package
MXDA3KP13A uses a 2-pin DO-214AB (SMC) package with cathode-anode polarity: Pin 1 = Cathode, Pin 2 = Anode. Body marking includes date code and part number; polarity defined by dot on top surface. Package meets UL94V-0 flammability rating and weighs ~5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., DC input); conducts during positive transient events. |
| Pin 2 | Anode | Connected to ground reference; completes current path during clamping action. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables single-device protection against IEC61000-4-5 Class 4 surges (4 kV, 42 Ω source) without cascading devices. |

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 rating (vs. 3000 W); same VWM and DO-214AA package; lower clamping voltage (21.2 V). | Not suitable for IEC61000-4-5 Class 4; limited to Class 1–2 or low-energy ESD/EFT only. | Select SMBJ13A only when system-level surge energy is confirmed ≤600 W and PCB space constraints prohibit SMC footprint. |
| 1.5KE13A | 3000 W rating but axial-leaded DO-201AD package; higher thermal resistance; no RoHS e3 marking. | Requires through-hole assembly; incompatible with automated SMT lines; lacks MIL-PRF-19500 screening path. | Choose 1.5KE13A only for legacy through-hole designs where rework to SMT is not feasible. |
Compared with SMBJ13A and 1.5KE13A, MXDA3KP13A uniquely combines 3000 W SMT capability, RoHS e3 plating, and MIL-PRF-19500 upscreening eligibility-making it the only option for new high-reliability industrial SMT designs requiring Class 4 surge immunity.

FAQ
What is the clamping voltage of MXDA3KP13A at its rated peak pulse current?
The MXDA3KP13A 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 measured per standard TVS test methodology and guarantees voltage limiting during high-energy transients, protecting downstream components such as DC-DC controllers and gate drivers in the MXDA3KP13A application circuit.
Is MXDA3KP13A RoHS compliant and what plating does it use?
Yes, MXDA3KP13A is RoHS compliant (e3 designation), featuring annealed matte-tin plating on its terminals. This plating ensures reliable solderability per MIL-STD-750 Method 2026 and supports lead-free reflow profiles up to 260 °C for 10 seconds. The e3 marking is laser-etched on the device body, and MXDA3KP13A meets IPC/JEDEC J-STD-020B moisture sensitivity Level 1 without dry pack.
Does MXDA3KP13A support MIL-PRF-19500 upscreening and what does that include?
Yes, MXDA3KP13A qualifies for optional MIL-PRF-19500 upscreening per Micronote 129. This includes wafer fabrication and assembly lot traceability, 3σ statistical screening on standby current (ID), and conformance inspections such as burn-in and hermeticity testing. These enhancements make MXDA3KP13A suitable for aerospace, defense, and critical infrastructure programs where reliability validation is mandatory.
What is the polarity configuration and pin identification method for MXDA3KP13A?
MXDA3KP13A is a unidirectional TVS with cathode-anode polarity: Pin 1 is cathode, Pin 2 is anode. Polarity is identified by a molded dot on the top surface adjacent to Pin 1. This marking aligns with the DO-214AB (SMC) package standard and ensures correct orientation during SMT placement-critical for proper clamping behavior in the MXDA3KP13A circuit layout.
How does MXDA3KP13A perform under IEC61000-4-5 secondary lightning testing?
MXDA3KP13A is validated for IEC61000-4-5 secondary lightning protection across Class 1–4 with 42 Ω source impedance, and Class 1–3 with 12 Ω and Class 2 with 2 Ω source impedance. Its 3000 W rating and 21.5 V clamping voltage enable compliance without derating at 25 °C, and its derating curve (Figure 3) supports operation up to +150 °C junction temperature in real-world deployments of MXDA3KP13A.
