Product details
Overview
MADA3KP36AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 36 V standoff voltage (VWM), 40.0–44.2 V breakdown voltage (V(BR)), and 58.1 V maximum clamping voltage (VC) at 51.6 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 telecom power interfaces.
For engineers reviewing the MADA3KP36AE3 datasheet, MADA3KP36AE3 pinout, MADA3KP36AE3 application, or MADA3KP36AE3 equivalent, key selection criteria include its 36 V working voltage, 58.1 V clamping performance at 51.6 A, RoHS-compliant e3 termination, and MIL-PRF-19500 upscreening capability for high-reliability aerospace and defense systems.
Technical Context
The MADA3KP36AE3 operates as a unidirectional avalanche diode-based TVS array, designed for parallel connection across DC power rails or signal lines to shunt transient energy to ground. Its sub-100 ps response time enables effective suppression of ESD events and fast-rising inductive spikes.
It is rated for 3000 W peak pulse power under 10/1000 µs waveform, with thermal derating above 25 °C per Figure 3, and supports solder reflow up to 260 °C for lead-free assembly. Polarity is defined by dot marking; odd-numbered pins are cathodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | 600 W rating, 58.1 V clamping, DO-214AA package (smaller footprint) | Lower energy handling; suitable only for ESD/EFT, not secondary lightning | Select SMBJ36A where board space is constrained and surge threat level is Class 2 or lower |
| 1.5KE36A | Through-hole TO-218 package, same 36 V VWM and 58.1 V VC, but 1500 W rating | Requires PCB through-holes; less suitable for automated SMT production | Choose 1.5KE36A for legacy designs or where mechanical robustness outweighs assembly efficiency |
Compared with SMBJ36A and 1.5KE36A, the MADA3KP36AE3 delivers triple the peak pulse power (3000 W vs. 600 W / 1500 W) in an SMT package, enabling single-device protection against IEC61000-4-5 Class 4 threats without parallel staging or heatsinking.

FAQ
What is the clamping voltage of the MADA3KP36AE3 at its rated peak pulse current?
The MADA3KP36AE3 has a maximum clamping voltage (VC) of 58.1 V at its rated peak pulse current (IPP) of 51.6 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 a full-rated surge event. The MADA3KP36AE3 achieves this clamping performance while maintaining sub-100 ps response time and low leakage.
Is the MADA3KP36AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, the MADA3KP36AE3 is RoHS compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies matte-tin plating on terminations, fully compliant with Directive 2011/65/EU and compatible with lead-free reflow processes up to 260 °C. This ensures environmental compliance without compromising solder joint reliability or thermal cycling endurance in the MADA3KP36AE3.
Can the MADA3KP36AE3 be used for bidirectional transient protection?
No, the MADA3KP36AE3 is unidirectional, as indicated by the absence of a 'C' suffix in its part number. Bidirectional variants (e.g., MADA3KP36CE3) exist in the same family but feature symmetrical breakdown in both polarities. Using the unidirectional MADA3KP36AE3 on AC or bipolar signal lines would result in forward conduction during negative half-cycles, potentially damaging the device or circuit. Always verify polarity alignment before deploying the MADA3KP36AE3.
What is the standoff voltage (VWM) and why is it critical for selecting the MADA3KP36AE3?
The MADA3KP36AE3 has a rated working standoff voltage (VWM) of 36 V, meaning it remains non-conductive up to this DC or peak AC voltage across its terminals. Selecting a VWM ≥ the system's maximum normal operating voltage prevents false triggering and leakage-related power loss. For a 33 V nominal rail, the MADA3KP36AE3 provides 3 V margin-ensuring reliable blocking while allowing headroom for ripple and tolerance, which is essential for stable protection in the MADA3KP36AE3.
Does the MADA3KP36AE3 require derating at elevated ambient temperatures?
Yes, the MADA3KP36AE3 requires thermal derating above 25 °C ambient, as shown in Figure 3 of its datasheet. Its 3000 W peak pulse power rating decreases linearly to ~50% at +125 °C junction temperature. System designers must calculate worst-case junction temperature-including power dissipation, PCB copper area, and airflow-to ensure the MADA3KP36AE3 maintains required surge capability. Derating curves are provided to support accurate thermal design validation for the MADA3KP36AE3.
