Product details
Overview
MADA3KP30CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in DC power lines and signal interfaces. It features a 30 V standoff voltage (VWM), 33.3–36.8 V breakdown voltage (V(BR)), 48.4 V clamping voltage at 62 A peak pulse current, and operates across –55 °C to +150 °C junction temperature. It protects against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and secondary lightning surges (IEC61000-4-5) in industrial power supplies.
For engineers reviewing the MADA3KP30CA datasheet, MADA3KP30CA pinout, MADA3KP30CA application, or MADA3KP30CA equivalent, key selection criteria include bidirectional polarity, 30 V working voltage, 48.4 V clamping at 62 A, 100 ps response time, and compliance with MIL-PRF-19500 screening options for aerospace-grade reliability.
Technical Context
The MADA3KP30CA is a surface-mount, void-free epoxy-packaged TVS array with cathode-defined odd-numbered pins and RoHS-compliant matte-tin plating. Its bidirectional construction enables symmetrical clamping on AC-coupled or floating lines without polarity concerns.
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). Clamping occurs within 100 ps for unidirectional and <5 ns for bidirectional variants-ensuring sub-nanosecond response to fast transients like ESD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V maximum continuous reverse standoff voltage - sets upper limit of normal operating voltage before clamping initiates |
| V(BR) min–max | 33.3–36.8 V breakdown range at 1 mA - defines reliable turn-on threshold under controlled test conditions |
| VC @ IPP | 48.4 V clamping voltage at 62 A peak pulse - limits downstream voltage stress during worst-case 10/1000 µs surge |
| PPP | 3000 W peak pulse power rating - supports high-energy lightning-induced transients per IEC61000-4-5 Class 1–4 |
| TJ range | –55 °C to +150 °C operating junction temperature - enables deployment in harsh automotive, aerospace, and industrial environments |
| ID @ VWM | ≤2 µA standby leakage at 30 V - ensures minimal power loss and no false triggering in low-power monitoring circuits |
| Response time | <5 ns for bidirectional mode - guarantees effective suppression of ESD events faster than typical IC input protection diodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | 600 W PPP rating, SMC package, 45.7 V VC @ 13.3 A - lower energy handling and smaller footprint | Suitable for consumer electronics with lower surge exposure; insufficient for IEC61000-4-5 Class 3/4 | Select when board space is constrained and surge threat level is limited to ESD/EFT only |
| SMCJ30CA | 1500 W PPP rating, same SMC package, 48.4 V VC @ 31 A - half the energy capacity of MADA3KP30CA | Valid for IEC61000-4-5 Class 1–2 (42 Ω), but fails Class 3/4 validation at 12 Ω source impedance | Choose where cost is prioritized over full lightning immunity and system-level reliability is non-critical |
Compared with SMBJ30CA and SMCJ30CA, the MADA3KP30CA provides double the peak pulse power (3000 W vs. 1500/600 W), enabling robust secondary lightning protection in industrial and aerospace systems where single-event survivability is mandated.

FAQ
What is the clamping voltage of the MADA3KP30CA at its rated peak pulse current?
The MADA3KP30CA has a maximum clamping voltage (VC) of 48.4 V at 62 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in the RF01243 datasheet and ensures downstream components remain below their absolute maximum voltage ratings during surge events. The MADA3KP30CA maintains this clamping performance across its full operating temperature range.
Is the MADA3KP30CA suitable for protecting CAN bus interfaces?
Yes, the MADA3KP30CA is suitable for CAN bus protection due to its bidirectional configuration, 48.4 V clamping voltage, and <5 ns response time - all critical for preserving signal integrity while suppressing ±15 kV ESD per IEC61000-4-2. Its 30 V standoff allows safe integration on 24 V or 28 V CAN networks. The MADA3KP30CA's low leakage (<2 µA) also prevents bus loading during normal operation.
Does the MADA3KP30CA meet IEC61000-4-5 Class 4 lightning surge requirements?
Yes, the MADA3KP30CA meets IEC61000-4-5 Class 4 for secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the RF01243 datasheet Applications section. It also supports Class 1–3 with 12 Ω and Class 2–4 with 2 Ω source impedances depending on voltage grade. The MADA3KP30CA's 3000 W rating directly enables this compliance without derating.
What does the "C" suffix in MADA3KP30CA indicate?
The "C" suffix in MADA3KP30CA explicitly denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients across its terminals. This distinguishes it from unidirectional variants like MADA3KP30A and makes the MADA3KP30CA ideal for AC-coupled, floating, or differential signal paths where polarity reversal is possible.
Can the MADA3KP30CA be used in aerospace applications requiring high-reliability screening?
Yes, the MADA3KP30CA supports optional MIL-PRF-19500 upscreening - including wafer and assembly lot traceability, 3σ standby current screening, and extended environmental testing - making it suitable for aerospace avionics power buses. This screening path is documented in Micronote 129 and enabled through Microsemi's qualified manufacturing flow. The MADA3KP30CA's base qualification already includes full-unit surge testing and moisture sensitivity Level 1 compliance.
