Product details
Overview
MADA3KP20AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 20 V standoff voltage (VWM), 22.2–24.5 V breakdown voltage (V(BR)), and 32.4 V maximum clamping voltage (VC) at 92.6 A peak pulse current (IPP). 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 DC power rails.
For engineers reviewing the MADA3KP20AE3 datasheet, MADA3KP20AE3 pinout, MADA3KP20AE3 application, or MADA3KP20AE3 equivalent, key selection criteria include its 20 V working voltage, sub-100 ps response time, RoHS-compliant e3 marking, MIL-PRF-19500 upscreening capability, and 5 g package weight for high-reliability industrial and aerospace power rail protection.
Technical Context
The MADA3KP20AE3 operates as a unidirectional avalanche diode-based TVS array, designed for parallel connection across protected lines to clamp transients before downstream ICs are damaged. Its 3000 W peak pulse power rating is specified at 10/1000 µs waveform with ≤0.05% duty factor, and it exhibits <100 ps response time from 0 V to V(BR) min.
It features a thermosetting epoxy body (UL94V-0), tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026, and polarity defined by odd-numbered pins as cathodes. The device is rated for -55 °C to +150 °C junction temperature and undergoes 3σ lot norm screening on standby current (ID).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ20A | 600 W PPP rating (vs. 3000 W); same VWM (20 V), but higher VC (32.4 V vs. 34.0 V); DO-214AC package. | Limited to lower-energy transients; not suitable for IEC61000-4-5 Class 4 or lightning-level events. | Select SMAJ20A only for cost-sensitive, low-surge environments where 600 W suffices and board space is constrained. |
| SMCJ20A | 1500 W PPP rating (vs. 3000 W); identical VWM (20 V), slightly higher VC (32.4 V vs. 33.2 V); same DO-214AB package. | Provides intermediate surge capability; insufficient for full Class 4 lightning per 42 Ω source impedance. | Choose SMCJ20A when 1500 W meets system test requirements and legacy design reuse is prioritized over maximum ruggedness. |
Compared with SMAJ20A and SMCJ20A, the MADA3KP20AE3 delivers triple the peak pulse power of SMCJ20A and five times that of SMAJ20A-enabling reliable protection in high-energy environments such as avionics, industrial motor drives, and renewable energy systems where 3000 W surge handling is mandated.

FAQ
What is the clamping voltage of MADA3KP20AE3 at its rated peak pulse current?
The MADA3KP20AE3 has a maximum clamping voltage (VC) of 32.4 V at its rated peak pulse current (IPP) of 92.6 A under 10/1000 µs waveform conditions. This value is measured per standard test methods and represents the worst-case overvoltage imposed on protected circuitry during a full-rated surge event. The MADA3KP20AE3 maintains this clamping performance across its full operating temperature range.
Is MADA3KP20AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MADA3KP20AE3 is RoHS compliant-the 'e3' suffix explicitly denotes annealed matte-tin plating meeting EU Directive 2011/65/EU requirements. This termination type replaces traditional tin-lead finishes while maintaining solderability per MIL-STD-750 Method 2026. The MADA3KP20AE3 also complies with moisture sensitivity Level 1 per J-STD-020B, eliminating dry-pack requirements for SMT processing.
Can MADA3KP20AE3 be used for bidirectional transient suppression?
No, MADA3KP20AE3 is a unidirectional TVS device, as confirmed by its part number structure (no 'C' suffix) and electrical specifications-including forward clamping voltage (VFS = 4.0 V) and asymmetric breakdown behavior. For bidirectional protection, Microsemi offers the MADA3KP20CE3 variant. Using MADA3KP20AE3 in AC or bipolar signal paths would result in unintended forward conduction and potential failure.
What is the maximum operating temperature range for MADA3KP20AE3?
The MADA3KP20AE3 is rated for junction and storage temperatures from -55 °C to +150 °C, verified per manufacturer specifications. This wide range supports deployment in harsh environments such as engine compartments, avionics bays, and outdoor renewable energy installations. Derating of peak pulse power begins above 25 °C, following the curve in Figure 3 of the RF01243 datasheet.
Does MADA3KP20AE3 require special PCB layout considerations?
Yes-MADA3KP20AE3 demands low-inductance layout to preserve its <100 ps response time. Short, wide traces between pins and protected nodes, direct grounding to solid planes, and avoidance of vias in the clamping path are essential. The device uses DO-214AB (SMC) package with Pin 1 identified by a dot; incorrect orientation will prevent proper clamping. Thermal relief on pads should be minimized to ensure adequate surge current handling.
