Product details
Overview
MADA3KP30A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. It features a 30 V reverse standoff voltage (VWM), 33.3–36.8 V breakdown voltage (V(BR)), 48.4 V maximum clamping voltage at 62 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP30A datasheet, MADA3KP30A pinout, MADA3KP30A application, or MADA3KP30A equivalent, key selection criteria include IEC61000-4-5 Class 1–4 secondary lightning compliance with 42 Ω source impedance, 10/1000 μs surge capability, and RoHS-compliant void-free epoxy packaging suitable for automated SMT assembly.
Technical Context
The MADA3KP30A implements a silicon avalanche diode structure optimized for sub-100 ps response time in unidirectional configuration, enabling suppression of fast transients including ESD (IEC61000-4-2) and EFT (IEC61000-4-4). Its clamping behavior is characterized under 10/1000 μs waveform with 0.05% duty factor, delivering stable 48.4 V VC at 62 A IPP.
Designed for high-reliability applications, it undergoes full lot surge testing and 3σ screening on standby current (ID ≤ 2 μA @ 30 V), with wafer and assembly lot traceability per MIL-PRF-19500 optional upscreening. Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ30A | 600 W PPP rating, DO-214AC package, 48.4 V VC @ 12.3 A IPP | Lower energy handling; suited for consumer-grade 10/1000 μs surges, not Class 4 lightning | Select when cost-sensitive designs require basic ESD/EFT protection without industrial surge compliance |
| Vishay SM8S30A | 6600 W PPP, TO-277 package, 48.4 V VC @ 137 A IPP, higher thermal mass | Higher surge margin but larger footprint; requires re-layout for same PCB area | Choose for extended lifetime in repetitive surge environments where board space permits |
Compared with MADA3KP30A, SMAJ30A offers lower cost but insufficient 3000 W capability for IEC61000-4-5 Class 4, while SM8S30A delivers double the PPP with greater thermal robustness but demands mechanical redesign - MADA3KP30A uniquely balances military-grade reliability, SMT scalability, and exact 3000 W compliance in its form factor.

FAQ
What is the clamping voltage of MADA3KP30A under standard test conditions?
The MADA3KP30A has a maximum clamping voltage (VC) of 48.4 V when subjected to a 10/1000 μs peak pulse current of 62 A. This value is measured per IEC61000-4-5 test methodology and defines the upper voltage limit imposed on protected circuitry during surge events. The MADA3KP30A maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is MADA3KP30A RoHS compliant and what does the 'e3' marking indicate?
Yes, MADA3KP30A is RoHS compliant, indicated by the 'e3' suffix in its marking per Microsemi's nomenclature. The 'e3' designation confirms annealed matte-tin plating meeting JEDEC/IPC standards and full compliance with Directive 2011/65/EU, including restrictions on lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. The MADA3KP30A requires no exemption reporting for standard industrial use.
Can MADA3KP30A be used for bidirectional transient suppression?
No, MADA3KP30A is a unidirectional TVS device, as confirmed by its part number suffix 'A' (bidirectional variants use 'C', e.g., MDA3KP30CA). Its polarity is fixed: odd-numbered pins are cathodes, even-numbered pins are anodes. For bidirectional protection, MADA3KP30A must be paired with a complementary device or replaced with the MDA3KP30CA variant - the MADA3KP30A itself conducts only in reverse bias above V(BR).
What is the maximum peak pulse current rating for MADA3KP30A?
The MADA3KP30A is rated for a maximum peak pulse current (IPP) of 62 A under the standard 10/1000 μs double-exponential waveform. This value is derived directly from its 3000 W peak pulse power (PPP) rating and 48.4 V clamping voltage (VC), calculated as IPP = PPP / VC. The MADA3KP30A sustains this current without degradation when surge repetition rate remains ≤0.05% duty factor.
Does MADA3KP30A require pre-baking before reflow soldering?
No, MADA3KP30A does not require pre-baking prior to reflow soldering. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, meaning it may be stored indefinitely at ≤30 °C/60% RH without baking. The void-free epoxy package construction and Level 1 classification eliminate dry-pack requirements and simplify SMT line integration - a key advantage of the MADA3KP30A in high-volume manufacturing.
