Product details
Overview
MADA3KP20CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD protection. It features a 20 V standoff voltage (VWM), 22.2–24.5 V breakdown range (V(BR)), 32.4 V maximum clamping voltage at 92.6 A peak pulse current, and operates from −55 °C to +150 °C - deployed in telecom power interfaces and industrial I/O protection.
For engineers reviewing the MADA3KP20CAE3 datasheet, MADA3KP20CAE3 pinout, MADA3KP20CAE3 application, or MADA3KP20CAE3 equivalent, key selection criteria include bidirectional polarity, 3000 W 10/1000 µs surge rating, RoHS-compliant matte-tin plating, MIL-PRF-19500 upscreening eligibility, and compatibility with IEC61000-4-2/4-4/4-5 test levels.
Technical Context
The MADA3KP20CAE3 implements a silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transients. Its clamping behavior is characterized by a defined V(BR) min–max window and guaranteed VC ≤ 32.4 V at IPP = 92.6 A, enabling predictable overvoltage limiting in DC power rails and signal lines.
It complies with IEC61000-4-5 secondary lightning testing at multiple source impedances (2 Ω, 12 Ω, 42 Ω), supporting Class 1–4 protection depending on impedance configuration. Standby leakage ID ≤ 2 µA at 20 V ensures minimal power loss in always-on circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 20 V - maximum continuous operating voltage before conduction begins |
| V(BR) min–max | 22.2–24.5 V @ 1 mA - defines reliable avalanche onset window for design margining |
| VC @ IPP | 32.4 V @ 92.6 A - peak clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPP | 3000 W @ 10/1000 µs - peak power handling capacity for standardized surge events |
| ID @ VWM | ≤2 µA - ultra-low leakage preserves battery life and signal integrity in standby |
| TJ/TSTG | −55 °C to +150 °C - wide thermal range supports under-hood, industrial, and aerospace environments |
| Polarity | Bidirectional - protects against both positive and negative transients without external circuitry |
Pinout & Package
Package: DO-214AB (SMC), void-free UL94V-0 epoxy body, matte-tin plated terminals, pin 1 marked by dot, weight ≈5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ20CA | 600 W rating, DO-214AA package, lower IPP (32.4 A), same VWM/V(BR)/VC specs | Not suitable for IEC61000-4-5 Class 4; limited to Class 2–3 or ESD/EFT only | Select when board space is constrained and surge threat level is ≤600 W |
| SMCJ20CA | 1500 W rating, DO-214AB package, identical footprint, IPP = 64.5 A, VC = 32.4 V | Meets IEC61000-4-5 Class 3 (42 Ω), insufficient for Class 4 secondary lightning | Choose for cost-sensitive designs where 1.5 kW surge margin is sufficient and footprint reuse is critical |
Compared with SMBJ20CA and SMCJ20CA, the MADA3KP20CAE3 delivers 2× and 2× higher peak pulse power respectively, enabling robust Class 4 secondary lightning protection in telecom and industrial systems where 3000 W surge immunity is mandated.

FAQ
What does the 'C' suffix in MADA3KP20CAE3 indicate?
The 'C' suffix denotes bidirectional polarity - meaning the MADA3KP20CAE3 conducts and clamps symmetrically for both positive and negative transients. This eliminates the need for polarity-aware layout and enables use on AC-coupled or floating DC lines. Unlike unidirectional variants (e.g., MADA3KP20AE3), the MADA3KP20CAE3 has no designated anode or cathode terminal in normal operation.
Is MADA3KP20CAE3 RoHS compliant?
Yes, MADA3KP20CAE3 is RoHS compliant, as confirmed by the 'e3' suffix in the part number per Microsemi's nomenclature. It uses annealed matte-tin plating per MIL-STD-750 Method 2026 and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - requiring no dry pack or bake-out prior to reflow soldering.
What is the maximum clamping voltage of MADA3KP20CAE3 under surge conditions?
The maximum clamping voltage (VC) of MADA3KP20CAE3 is 32.4 V at 92.6 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is guaranteed across temperature and process variation, providing a deterministic upper bound for protected circuit voltage during surge events.
Can MADA3KP20CAE3 be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MADA3KP20CAE3 is rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance. Its 3000 W peak pulse power rating and validated clamping performance meet the 4 kV open-circuit voltage requirement for Class 4, as documented in Microsemi RF01243 Rev B.
What is the standoff voltage and breakdown range for MADA3KP20CAE3?
MADA3KP20CAE3 has a rated working standoff voltage (VWM) of 20 V and a minimum–maximum breakdown voltage (V(BR)) range of 22.2 V to 24.5 V at 1 mA test current. This 11.5% tolerance window ensures consistent avalanche initiation while allowing design margin between operating voltage and conduction threshold.
