Product details
Overview
MADA3KP11CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and telecom power interfaces. It features a 11 V reverse standoff voltage (VWM), 12.2–13.5 V breakdown voltage (V(BR)), 18.2 V maximum clamping voltage at 164.8 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP11CA datasheet, MADA3KP11CA pinout, MADA3KP11CA application, or MADA3KP11CA equivalent, key selection criteria include IEC61000-4-5 secondary lightning compliance (Class 1–4 with 42 Ω source), ESD/EFT immunity per IEC61000-4-2/4-4, and bidirectional clamping behavior for AC-coupled signal or power lines.
Technical Context
The MADA3KP11CA implements a silicon avalanche diode structure optimized for sub-5 ns response time and low clamping ratio (VC/V(BR) ≈ 1.42). Its bidirectional configuration enables symmetrical transient suppression on AC or differential lines without polarity constraints.
It delivers 3000 W peak pulse power at 10/1000 µs waveform, with full surge testing per unit and 3σ lot norm screening on standby current (ID ≤ 5 µA @ VWM). Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - maximum continuous operating voltage before conduction begins; matches nominal 12 V rail systems |
| V(BR) min/max | 12.2–13.5 V - verified avalanche onset range at 1 mA; ensures predictable turn-on margin above VWM |
| VC @ IPP | 18.2 V - clamping voltage at 164.8 A peak pulse; limits downstream voltage stress during surge events |
| IPP | 164.8 A - peak impulse current capability at 10/1000 µs; supports IEC61000-4-5 Class 4 (42 Ω) |
| ID @ VWM | ≤5 µA - ultra-low leakage at rated standoff; preserves system power integrity in always-on circuits |
| TJ range | –55 °C to +150 °C - qualified for harsh environments including automotive under-hood and industrial motor drives |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | 600 W rating (vs. 3000 W); same VWM and bidirectional configuration; DO-214AA package | Limited to lower-energy threats (IEC61000-4-5 Class 2); unsuitable for 42 Ω Class 4 lightning | Select when space-constrained layouts require smaller footprint and threat profile is limited to ESD/EFT only |
| 1.5KE11CA | 3000 W rating; axial-leaded DO-201 package; higher thermal resistance than SMC | Not suitable for automated SMT assembly; requires through-hole rework or adapter; less robust mechanical mounting | Select only for legacy through-hole designs where board re-spin is not feasible |
Compared with SMBJ11CA and 1.5KE11CA, the MADA3KP11CA provides superior energy handling in surface-mount form factor, enabling direct replacement in high-surge industrial power interfaces without compromising layout density or manufacturability.

FAQ
What is the clamping voltage of the MADA3KP11CA at its rated peak pulse current?
The MADA3KP11CA has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPP) of 164.8 A under 10/1000 µs waveform conditions. This value is guaranteed across temperature and ensures downstream circuitry remains within safe operating limits during surge events. The MADA3KP11CA achieves this performance using a tightly controlled silicon avalanche junction with low dynamic impedance.
Is the MADA3KP11CA suitable for IEC61000-4-5 Class 4 lightning surge testing?
Yes, the MADA3KP11CA is rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance. Its 3000 W peak pulse power rating and 164.8 A IPP capability meet the 4 kV test requirement. The MADA3KP11CA's bidirectional architecture ensures symmetrical clamping regardless of surge polarity, making it appropriate for AC-coupled or floating interfaces.
Does the MADA3KP11CA require moisture-sensitive handling or dry pack storage?
No, the MADA3KP11CA has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it does not absorb significant moisture during standard factory handling and requires no dry pack storage or baking prior to reflow. This simplifies manufacturing logistics and eliminates yield loss from popcorning. The MADA3KP11CA's thermosetting epoxy body contributes to its robust MSL rating.
How does the bidirectional configuration of the MADA3KP11CA affect its use in DC power lines?
The MADA3KP11CA's bidirectional design allows it to clamp both positive and negative transients on DC lines - for example, suppressing load dump spikes and reverse-polarity connection events on 12 V systems. Unlike unidirectional TVS devices, the MADA3KP11CA does not require external polarity alignment, reducing design complexity. Its symmetric V-I curve ensures consistent protection regardless of transient direction.
Can the MADA3KP11CA be used in place of the MDA3KP11A in existing designs?
No - the MADA3KP11CA and MDA3KP11A differ in polarity: MADA3KP11CA is bidirectional (suffix "C"), while MDA3KP11A is unidirectional. Substituting them without circuit review risks improper clamping during negative transients. The MADA3KP11CA must be validated in context of the target application's signal polarity, grounding scheme, and surge directionality before replacement.
