Product details
Overview
MADA3KP16CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in industrial and aerospace power interfaces. It features a 16 V standoff voltage (VWM), 17.8–19.7 V breakdown range (V(BR)), 26.0 V maximum clamping voltage (VC) at 115.4 A peak pulse current, and operates across –55 °C to +150 °C junction temperature. It protects against IEC61000-4-5 secondary lightning (42 Ω, Class 1–4), ESD per IEC61000-4-2, and EFT per IEC61000-4-4.
For engineers reviewing the MADA3KP16CA datasheet, MADA3KP16CA pinout, MADA3KP16CA application, or MADA3KP16CA equivalent, this device serves as a surface-mount, RoHS-compliant, bidirectional TVS with verified 3000 W surge rating, precise clamping performance, and MIL-PRF-19500 upscreening capability for mission-critical systems requiring robust overvoltage immunity.
Technical Context
The MADA3KP16CA implements a silicon avalanche diode structure optimized for fast response (<5 ns) and low clamping ratio (VC/V(BR) ≈ 1.38). Its bidirectional configuration enables symmetrical protection of AC lines or differential signal paths without polarity constraints.
It is rated for 10/1000 μs waveform surges up to 3000 W, with full surge testing performed per unit lot and 3σ screening on standby current (ID ≤ 2 μA at VWM). Moisture sensitivity is Level 1 per J-STD-020B - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous operating voltage before conduction begins |
| V(BR) min–max | 17.8–19.7 V @ 1 mA - guaranteed avalanche onset range for reliable triggering |
| VC @ IPP | 26.0 V @ 115.4 A - clamping voltage limits downstream component stress during worst-case surge |
| PPP | 3000 W @ 10/1000 μs - peak power handling capacity defines surge energy absorption capability |
| ID @ VWM | ≤2 μA - ultra-low leakage preserves system efficiency and battery life in always-on circuits |
| TJ/TSTG | –55 °C to +150 °C - wide thermal range supports operation in harsh environments including avionics and motor drives |
| Response time | <5 ns - ensures protection before sensitive ICs experience damaging overvoltage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | 600 W PPP rating, same VWM and bidirectional configuration, smaller SMB package | Lower energy handling; suitable only for IEC61000-4-2/4-4, not Class 4 lightning | Select when board space is constrained and surge threat level is limited to ESD/EFT |
| 1.5KE16CA | 3000 W PPP but axial-leaded DO-201 package, higher thermal resistance, no MIL screening option | Lacks surface-mount compatibility and upscreening path for high-reliability programs | Select for cost-sensitive, non-mission-critical designs where through-hole assembly is acceptable |
Compared with SMBJ16CA and 1.5KE16CA, the MADA3KP16CA uniquely combines 3000 W surge capacity, SMC surface-mount packaging, bidirectional symmetry, and optional MIL-PRF-19500 screening - making it the only choice for compact, high-reliability, lightning-rated industrial and aerospace power interfaces.

FAQ
What is the clamping voltage of the MADA3KP16CA at its rated peak pulse current?
The MADA3KP16CA has a maximum clamping voltage (VC) of 26.0 V at its rated peak pulse current (IPP) of 115.4 A under 10/1000 μs waveform conditions. This value is measured across the device terminals during surge conduction and defines the upper voltage limit imposed on protected circuitry. The MADA3KP16CA maintains this clamping performance consistently across its operational temperature range and after multiple surge events, as verified by lot-level surge testing.
Is the MADA3KP16CA suitable for IEC61000-4-5 Class 4 lightning protection?
Yes, the MADA3KP16CA is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as confirmed in the manufacturer's application guidance. Its 3000 W peak pulse power rating and 26.0 V clamping voltage ensure compliance when applied with appropriate PCB layout and upstream impedance. The MADA3KP16CA achieves this performance in its standard configuration - no derating or external components are required for Class 4 validation at 25 °C.
Does the MADA3KP16CA require moisture preconditioning before reflow soldering?
No, the MADA3KP16CA has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions and does not require dry packing or baking prior to reflow. This eliminates moisture-related popcorning risk and simplifies manufacturing flow. The MADA3KP16CA's void-free epoxy encapsulation and hermetic-like sealing contribute to this robust MSL rating.
What does the "C" suffix in MADA3KP16CA indicate?
The "C" suffix in MADA3KP16CA denotes bidirectional construction - meaning the device contains two back-to-back avalanche diodes enabling symmetrical clamping for both polarities of transient voltage. This allows protection of AC-coupled signals, differential buses, or ungrounded power rails without polarity concerns. The MADA3KP16CA's pinout (Pin 1–2–3) reflects this internal dual-diode topology, with Pin 2 serving as the common center terminal.
Can the MADA3KP16CA be used in automotive applications?
The MADA3KP16CA is not AEC-Q200 qualified and lacks automotive-specific qualification documentation; however, its –55 °C to +150 °C operating range, 3000 W surge rating, and RoHS compliance make it technically viable for under-hood or infotainment power rail protection where customer-specific validation is performed. For production automotive use, formal AEC-Q200 testing and PPAP submission would be required - the MADA3KP16CA itself is not pre-qualified for that standard.
