Product details
Overview
MDA3KP13AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 13 V standoff voltage (VWM), 14.4–15.9 V breakdown range (V(BR)), and 21.5 V maximum clamping voltage (VC) at 139.4 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in power supply inputs and telecom interfaces.
For engineers reviewing the MDA3KP13AE3 datasheet, MDA3KP13AE3 pinout, MDA3KP13AE3 application, or MDA3KP13AE3 equivalent, this page delivers verified electrical parameters, RoHS-compliant package dimensions, polarity marking convention, surge test validation, and high-reliability screening options aligned with MIL-PRF-19500.
Technical Context
The MDA3KP13AE3 operates as a unidirectional avalanche diode-based TVS, designed for fast-clamping response (<100 ps rise time) to protect downstream circuitry from high-energy transients. Its 13 V rated standoff voltage ensures compatibility with 12 V nominal systems while maintaining margin against normal operating peaks.
It delivers 3000 W peak pulse power at 10/1000 µs waveform, validated under ≤0.05% duty cycle, with full surge testing per production lot and 3σ screening on standby current (ID ≤ 5 µA @ VWM). The device uses void-free UL94V-0 epoxy packaging with tin-lead or matte-tin terminations solderable per MIL-STD-750 Method 2026.
Key Specifications

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, same VWM (13 V), but lower IPP (53.3 A) and higher VC (21.5 V vs. 21.5 V - identical value but tested at lower current) | Limited to Class 2 IEC61000-4-5 (42 Ω) and light-duty ESD; insufficient for full Class 4 lightning events | Select MDA3KP13AE3 when 3000 W surge handling and MIL-PRF-19500 screening are required; SMBJ13A suits cost-sensitive consumer-grade designs. |
| SMCJ13A | 1500 W PPP, same VWM and VC (21.5 V), but IPP = 70 A - half the current-handling capability of MDA3KP13AE3 | Valid for Class 3 lightning (42 Ω), but fails Class 4 compliance; lacks optional high-reliability screening | Choose MDA3KP13AE3 for mission-critical infrastructure where full 3000 W margin and lot traceability are mandatory; SMCJ13A fits mid-tier industrial controls. |
Compared with SMBJ13A and SMCJ13A, MDA3KP13AE3 delivers double the peak pulse power and certified surge testing per lot, enabling reliable Class 4 lightning protection in telecom and transportation systems where failure modes carry safety or regulatory consequences.

FAQ
What is the clamping voltage of MDA3KP13AE3 and how is it measured?
The MDA3KP13AE3 has a maximum clamping voltage (VC) of 21.5 V, measured at its peak pulse current (IPP) of 139.4 A under standardized 10/1000 µs waveform conditions. This value represents the upper limit of voltage seen by protected circuitry during worst-case surge events and is confirmed per production lot testing, not just sample characterization.
Is MDA3KP13AE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MDA3KP13AE3 is RoHS-compliant. The 'e3' suffix explicitly denotes matte-tin termination plating meeting EU Directive 2011/65/EU requirements, with no lead content exceeding 0.1 wt%. This enables compatibility with Pb-free reflow profiles and eliminates post-assembly lead removal steps.
How does the polarity marking work on MDA3KP13AE3?
MDA3KP13AE3 uses a dot on the top surface to identify pin 1, which is the cathode of Channel 1. Per datasheet specification, all odd-numbered pins (1 and 3) are cathodes, while even-numbered pins (2 and 4) are anodes - enabling dual-channel unidirectional protection with shared or independent ground returns.
Can MDA3KP13AE3 be used for bidirectional protection?
No, MDA3KP13AE3 is unidirectional only. The 'A' suffix (vs. 'C') confirms unidirectional construction. For bidirectional applications, Microsemi offers the MDA3KP13CE3 variant, which features symmetrical breakdown in both directions and is designated for AC-coupled or floating signal line protection.
What screening options are available for MDA3KP13AE3 in high-reliability programs?
MDA3KP13AE3 supports optional upscreening per MIL-PRF-19500, including wafer lot traceability, 3σ statistical screening on standby current (ID), and conformance inspections. These options are documented in Micronote 129 and require factory coordination - standard parts ship without screening unless explicitly ordered.
