Product details
Overview
MADA3KP9.0CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array designed for high-reliability surge protection in power and signal lines. It features a 9.0 V reverse standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), 15.4 V maximum clamping voltage at 194.8 A peak pulse current, and operates across –55 °C to +150 °C junction temperature - deployed in industrial power supplies and telecom interface protection.
For engineers reviewing the MADA3KP9.0CA datasheet, MADA3KP9.0CA pinout, MADA3KP9.0CA application, or MADA3KP9.0CA equivalent, key selection criteria include IEC61000-4-5 secondary lightning compliance (Class 1–4 with 42 Ω/12 Ω/2 Ω source impedance), bidirectional polarity, RoHS-compliant e3 marking, and surface-mount package dimensions per RF01243 Rev B.
Technical Context
The MADA3KP9.0CA implements a silicon avalanche diode structure optimized for sub-nanosecond response (<5 ns) under bidirectional transients. Its clamping behavior is characterized at 10/1000 μs waveform with 3000 W peak pulse power rating and 194.8 A IPP, validated per Figure 2 in RF01243 Rev B.
It supports secondary lightning protection per IEC61000-4-5 across multiple source impedances: Class 1–4 at 42 Ω, Class 1–3 at 12 Ω, and Class 4 only at 2 Ω - with explicit inclusion of MADA3KP9.0CA in the Class 4 listing for 2 Ω configuration per page 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum continuous working voltage before conduction begins; sets minimum system operating margin. |
| V(BR) min/max | 10.0–11.1 V @ I(BR) - guaranteed avalanche onset range defining turn-on consistency across production lots. |
| VC @ IPP | 15.4 V @ 194.8 A - clamping voltage during full-rated 10/1000 μs surge; determines protected circuit's worst-case overvoltage exposure. |
| PPP | 3000 W @ 10/1000 μs - peak transient energy handling capacity; defines survivability against lightning-induced surges. |
| ID @ VWM | 10 μA - leakage current at rated standoff; ensures minimal standby power loss and signal integrity in high-impedance circuits. |
| TJ/TSTG | –55 °C to +150 °C - extended thermal envelope enabling use in under-hood automotive, industrial motor drives, and outdoor telecom enclosures. |
| Polarity | Bidirectional - protects both positive and negative transients without external polarity coordination; simplifies PCB layout for AC-coupled or floating lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0CA | 600 W PPP rating, 10.0–11.1 V V(BR), same VWM and polarity; smaller SMA package. | Limited to lower-energy transients (IEC61000-4-5 Class 2 max); unsuitable for 3000 W lightning tests. | Select when space-constrained layouts require SMT footprint reduction and surge energy is ≤600 W. |
| SMCJ9.0CA | 1500 W PPP rating, identical VWM/V(BR)/VC specs, DO-214AB package; no MIL-PRF-19500 screening option. | Valid for Class 3 lightning (42 Ω), but fails Class 4 due to lower energy rating; lacks high-reliability screening path. | Choose for cost-sensitive industrial designs where 1500 W surge capability suffices and upscreening is unnecessary. |
Compared with SMAJ9.0CA and SMCJ9.0CA, the MADA3KP9.0CA delivers 2× and 2× higher peak pulse power respectively, enables Class 4 lightning compliance, and supports traceable high-reliability screening - critical for mission-critical infrastructure where failure modes must be rigorously controlled.

FAQ
What is the clamping voltage of MADA3KP9.0CA at its rated peak pulse current?
The MADA3KP9.0CA has a maximum clamping voltage (VC) of 15.4 V at its rated peak pulse current (IPP) of 194.8 A under 10/1000 μs waveform conditions. This value is specified in the Electrical Characteristics table on page 3 of RF01243 Rev B and defines the upper voltage limit imposed on protected circuitry during full-rated surge events. The MADA3KP9.0CA maintains this clamping performance across its full operating temperature range.
Is MADA3KP9.0CA compliant with IEC61000-4-5 for secondary lightning protection?
Yes, the MADA3KP9.0CA is explicitly listed for secondary lightning protection per IEC61000-4-5 across multiple source impedances: Class 1–4 with 42 Ω, Class 1–3 with 12 Ω, and Class 4 with 2 Ω source impedance. This classification is confirmed in the APPLICATIONS / BENEFITS section on page 1 of RF01243 Rev B. The MADA3KP9.0CA meets these requirements due to its 3000 W peak pulse power rating and verified clamping behavior.
What does the "C" suffix in MADA3KP9.0CA indicate?
The "C" suffix in MADA3KP9.0CA denotes bidirectional polarity, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. As defined in the Part Nomenclature section on page 2 of RF01243 Rev B, "C = Bidirectional" and distinguishes it from unidirectional variants like MADA3KP9.0A. This allows the MADA3KP9.0CA to protect AC-coupled, floating, or differential signal paths without polarity constraints.
Does MADA3KP9.0CA require dry packing or baking before reflow soldering?
No, the MADA3KP9.0CA has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it is not moisture sensitive and requires no dry pack or pre-reflow baking. This is stated in the FEATURES section on page 1 of RF01243 Rev B. The MADA3KP9.0CA's thermosetting epoxy package inherently resists moisture absorption, simplifying manufacturing flow and reducing process risk.
What packaging and marking details apply to MADA3KP9.0CA?
The MADA3KP9.0CA uses a void-free transfer-molded thermosetting epoxy case (UL94V-0), weighs approximately 5 grams, and is marked with date code and full part number. Pin 1 is identified by a dot on the top surface, and terminals feature tin-lead or annealed matte-tin plating per MIL-STD-750 Method 2026. These mechanical specifications are documented in the MECHANICAL and PACKAGING section on page 2 of RF01243 Rev B.
