Product details
Overview
MADA3KP28AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 28 V standoff voltage (VWM), 31.1–34.4 V breakdown voltage (V(BR)), and 45.4 V maximum clamping voltage (VC) at 66 A peak pulse current. It delivers sub-100 ps response time, operates from −55 °C to +150 °C, and is RoHS-compliant (e3 suffix) for industrial surge protection in power supply inputs and communication interfaces.
For engineers reviewing the MADA3KP28AE3 datasheet, MADA3KP28AE3 pinout, MADA3KP28AE3 application, or MADA3KP28AE3 equivalent, key selection criteria include its 28 V working voltage, 45.4 V clamping performance at 66 A, 3000 W 10/1000 µs surge rating, polarity-defined pin layout, and MIL-PRF-19500 upscreening capability for high-reliability deployments.
Technical Context
The MADA3KP28AE3 is a single-channel unidirectional TVS diode designed for parallel connection across sensitive DC lines. Its silicon avalanche structure enables <100 ps response to transients, clamping voltages within 45.4 V at 66 A IPP under 10/1000 µs waveform, and maintains ≤2 µA standby current at 28 V VWM.
It complies with IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and IEC61000-4-5 (lightning) for secondary surge protection-supporting Class 1–4 per 42 Ω source impedance and Class 1–3 per 12 Ω source impedance-while requiring no dry pack due to IPC/JEDEC J-STD-020B Level 1 moisture sensitivity.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ28A | 600 W PPP rating, SMA package, 43.5 V VC @ 38.9 A IPP | Lower surge capacity; suited for consumer-grade, lower-energy interfaces | Select when board space is constrained and surge threat level is limited to ESD/EFT only |
| SMCJ28A | 1500 W PPP rating, SMC package, 45.4 V VC @ 33 A IPP | Half the peak power handling; requires derating in high-energy lightning zones | Choose where cost sensitivity outweighs need for full 3000 W immunity in industrial mains-connected systems |
Compared with SMAJ28A and SMCJ28A, the MADA3KP28AE3 provides double the surge energy margin of SMCJ28A and five times that of SMAJ28A-enabling robust protection in utility-grade power electronics and transportation infrastructure where IEC61000-4-5 Class 3–4 compliance is mandatory.

FAQ
What is the clamping voltage of MADA3KP28AE3 at its rated peak pulse current?
The MADA3KP28AE3 has a maximum clamping voltage (VC) of 45.4 V at 66 A peak pulse current (IPP), measured under standard 10/1000 µs waveform conditions. This value ensures downstream circuitry remains within safe voltage limits during high-energy transients. The MADA3KP28AE3 achieves this clamping performance while maintaining low leakage (<2 µA) at its 28 V standoff voltage, making it suitable for always-on protection schemes.
Is MADA3KP28AE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MADA3KP28AE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies annealed matte-tin plating and full compliance with EU RoHS Directive 2011/65/EU, including restriction of lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE. The MADA3KP28AE3 contains no lead in either die attach or terminal finish.
Does MADA3KP28AE3 support MIL-PRF-19500 screening and what does that entail?
MADA3KP28AE3 supports optional MIL-PRF-19500 upscreening, including wafer-level lot traceability, 3σ screening on standby current (ID), and conformance inspections per Microsemi Micronote 129. This screening validates reliability for aerospace and defense applications. While the base MADA3KP28AE3 is not automatically screened, qualified lots can be procured with these enhancements-making the MADA3KP28AE3 adaptable to both commercial and high-assurance use cases.
What is the thermal operating range of MADA3KP28AE3 and how does it affect derating?
The MADA3KP28AE3 operates from −55 °C to +150 °C junction temperature. Its 3000 W peak pulse power rating applies only at 25 °C; Figure 3 in the datasheet shows linear derating above 25 °C, reaching ~70% of rated power at +100 °C. Engineers must apply this derating when deploying the MADA3KP28AE3 in enclosed, high-ambient environments such as motor drive cabinets or solar inverter enclosures.
How is polarity defined on the MADA3KP28AE3 package and why does it matter for layout?
Polarity is defined by pin numbering: Pin 1 (marked with a dot) is the cathode, and Pin 2 is the anode. This unidirectional configuration means the MADA3KP28AE3 only clamps positive transients on the cathode side relative to anode (ground). Incorrect orientation-e.g., reversing cathode/anode-results in forward conduction during normal operation and device failure. PCB layout must observe the dot-marked Pin 1 and route accordingly to ensure correct clamping direction in the MADA3KP28AE3 application.
