Product details
Overview
MADA3KP12CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and aerospace systems. It features a 12 V reverse standoff voltage (VWM), 13.3–14.7 V breakdown voltage (V(BR)), 19.9 V maximum clamping voltage at 150.6 A peak pulse current, and operates across –55 °C to +150 °C. It protects power rails and I/O lines against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5).
For engineers reviewing the MADA3KP12CA datasheet, MADA3KP12CA pinout, MADA3KP12CA application, or MADA3KP12CA equivalent, key selection criteria include its bidirectional polarity, 10/1000 µs 3000 W surge rating, 19.9 V clamping performance at 150.6 A, MIL-PRF-19500 upscreening eligibility, and UL94V-0 void-free epoxy package.
Technical Context
The MADA3KP12CA is a surface-mount, dual-channel bidirectional TVS array with cathode-defined pinout (odd pins = cathodes). Its sub-5 ns response time enables effective suppression of fast transients including ESD and EFT events. The device uses silicon avalanche diode technology with controlled breakdown characteristics and is surge-tested per industry standards.
It complies with IEC61000-4-2 (±30 kV contact), IEC61000-4-4 (±4 kV), and IEC61000-4-5 (Class 1–4 secondary lightning, depending on source impedance). Clamping behavior is characterized at 150.6 A IPP under 10/1000 µs waveform, delivering 19.9 V VC while maintaining <5 µA ID at 12 V VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 13.3–14.7 V @ 1 mA - Ensures reliable avalanche initiation above operating rail |
| VC @ IPP | 19.9 V @ 150.6 A - Limits downstream voltage during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients without failure |
| ID @ VWM | <5 µA - Negligible leakage at rated standoff, preserving system efficiency |
| TJ/TSTG | –55 °C to +150 °C - Supports operation in extended-temperature avionics and industrial control |
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 |
|---|---|---|---|
| SMBJ12CA | 600 W PPP rating, same 12 V VWM and bidirectional polarity, but lower 19.9 V VC at only 32.4 A IPP | Not suitable for Class 3/4 IEC61000-4-5; limited to low-energy ESD/EFT and switching noise | Select SMBJ12CA only for space-constrained consumer-grade designs where 3000 W surge immunity is not required. |
| SMCJ12CA | 1500 W PPP, same VWM and VC spec, but rated for 65.1 A IPP - half the surge capacity of MADA3KP12CA | Acceptable for Class 1–2 lightning protection, but fails Class 3 testing with 12 Ω source impedance | Choose SMCJ12CA for cost-sensitive industrial controls where full 3000 W compliance is unnecessary. |
Compared with SMBJ12CA and SMCJ12CA, the MADA3KP12CA delivers double the surge energy handling of SMCJ12CA and five times that of SMBJ12CA - critical for mission-critical systems requiring validated Class 3/4 lightning immunity and MIL-PRF-19500 traceability.

FAQ
What is the clamping voltage of the MADA3KP12CA at its rated peak pulse current?
The MADA3KP12CA has a maximum clamping voltage (VC) of 19.9 V at its rated peak pulse current (IPP) of 150.6 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 MADA3KP12CA achieves this performance using tightly controlled avalanche breakdown characteristics and low dynamic impedance.
Is the MADA3KP12CA RoHS compliant?
Yes, the MADA3KP12CA is RoHS compliant, indicated by the "e3" suffix in its full marking per Microsemi's nomenclature. It uses annealed matte-tin plating on terminals and a void-free UL94V-0 epoxy body. The MADA3KP12CA meets lead-free reflow requirements with a 260 °C solder temperature rating for 10 seconds and requires no dry pack due to IPC/JEDEC J-STD-020B Level 1 moisture classification.
How does the MADA3KP12CA differ from unidirectional variants like MADA3KP12A?
The MADA3KP12CA is bidirectional, meaning it clamps voltage transients in both polarities using a back-to-back diode configuration (Pin 1–Pin 2–Pin 3), whereas MADA3KP12A is unidirectional (anode-cathode only). This makes the MADA3KP12CA suitable for AC-coupled lines, differential buses, or floating references where polarity reversal may occur. The MADA3KP12CA maintains identical VWM, V(BR), and VC specs but supports symmetric surge suppression.
Can the MADA3KP12CA be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, the MADA3KP12CA supports IEC61000-4-5 Class 4 secondary lightning protection when tested with 2 Ω source impedance, as confirmed in the official datasheet (RF01243, Rev B, Page 1). It also qualifies for Class 1–3 with 12 Ω source impedance and Class 1–4 with 42 Ω source impedance. Its 3000 W PPP rating and 150.6 A IPP ensure margin beyond minimum Class 4 test levels.
What is the thermal derating behavior of the MADA3KP12CA above 25 °C?
The MADA3KP12CA follows a linear derating curve starting at 25 °C, with peak pulse power decreasing to ~50% at +125 °C and zero at +150 °C (per Figure 3 in RF01243, Rev B). Designers must apply this derating when sizing for sustained high-temperature environments such as engine bays or enclosed inverters. The MADA3KP12CA's –55 °C to +150 °C junction range ensures functionality across the full curve without parameter shift.
