Product details
Overview
MADA3KP40AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 40 V standoff voltage (VWM), 44.4–49.1 V breakdown voltage (V(BR)), and 64.5 V clamping voltage (VC) at 46.4 A peak pulse current (IPP); used for secondary lightning protection per IEC61000-4-5 in telecom power interfaces.
For engineers reviewing the MADA3KP40AE3 datasheet, MADA3KP40AE3 pinout, MADA3KP40AE3 application, or MADA3KP40AE3 equivalent, key selection criteria include standoff voltage matching system DC rail, clamping margin relative to protected IC absolute maximum ratings, surge current capability under 10/1000 µs waveform, and RoHS-compliant matte-tin termination for lead-free reflow.
Technical Context
This TVS array operates as a high-energy, fast-response overvoltage clamp in series with DC power lines or signal paths. It exhibits <100 ps response time, 64.5 V clamping at 46.4 A IPP, and is rated for 3000 W peak pulse power under 10/1000 µs waveform with ≤0.05% duty factor.
Designed for unidirectional polarity, it features cathode-defined odd-numbered pins, void-free UL94V-0 epoxy packaging, and full surge testing per production lot. Standby leakage is limited to 2 µA at 40 V VWM, enabling low-power system compatibility.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ40A | 600 W PPP rating, same VWM and VC, but lower IPP (32.4 A) and smaller SMB package | Not suitable for IEC61000-4-5 Class 4; limited to Class 2/3 with 42 Ω source | Select when board space is constrained and surge energy is ≤600 W |
| 1.5KE40A | Through-hole DO-201 package, 1500 W PPP, higher thermal mass but no SMT compatibility | Requires manual insertion or wave solder; unsuitable for automated high-density PCB assembly | Choose only for legacy through-hole designs where rework tolerance outweighs automation needs |
Compared with SMBJ40A and 1.5KE40A, MADA3KP40AE3 delivers 2× higher surge energy handling than SMBJ40A and 2× higher than 1.5KE40A in an SMT-compatible package, making it optimal for new designs targeting IEC61000-4-5 Class 4 compliance with automated manufacturing.

FAQ
What is the clamping voltage of MADA3KP40AE3 at its rated peak pulse current?
The MADA3KP40AE3 has a maximum clamping voltage (VC) of 64.5 V at 46.4 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in the datasheet and represents the upper bound voltage imposed on protected circuitry during worst-case surge events. Designers must verify that this clamping level remains safely below the absolute maximum ratings of downstream components when using MADA3KP40AE3 in their system.
Is MADA3KP40AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MADA3KP40AE3 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 meeting EU Directive 2011/65/EU requirements and ensures compatibility with Pb-free reflow soldering processes. This compliance is verified through material declarations and plating process controls documented in Microsemi's quality system, and applies to every unit of MADA3KP40AE3 shipped.
How many channels does MADA3KP40AE3 contain and how are they configured?
MADA3KP40AE3 is a dual-channel unidirectional TVS array housed in a 4-pin DO-214AB (SMC) package. Pins 1 and 2 form Channel 1 (cathode-anode), while Pins 3 and 4 form Channel 2 (cathode-anode). Both channels share identical electrical specifications - including 40 V VWM and 64.5 V VC - enabling independent protection of two DC rails or differential signal lines without cross-talk or shared thermal limitations.
What is the maximum operating temperature range for MADA3KP40AE3?
MADA3KP40AE3 is rated for junction and storage temperatures from -55°C to +150°C, as specified in the Absolute Maximum Ratings table. This wide range supports deployment in harsh environments such as under-hood automotive applications, outdoor telecom cabinets, and industrial motor control enclosures. Derating of peak pulse power begins above 25°C per Figure 3 in the datasheet, with 50% power capability retained at +125°C ambient.
Can MADA3KP40AE3 be used for bidirectional transient suppression?
No, MADA3KP40AE3 is strictly unidirectional, as indicated by the absence of a 'C' suffix in its part number. Bidirectional variants (e.g., MADA3KP40CE3) exist in the same family but feature symmetrical breakdown characteristics for AC or bipolar signal line protection. Using MADA3KP40AE3 on AC-coupled or floating lines may result in unintended conduction or failure to clamp negative transients; always match polarity type to system topology when selecting MADA3KP40AE3.
