Product details
Overview
MADA3KP26AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability surge protection in power rails and signal lines. It features a 26 V reverse standoff voltage (VWM), 28.9–31.9 V breakdown voltage (V(BR)), 42.1 V maximum clamping voltage at 71.2 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).
For engineers reviewing the MADA3KP26AE3 datasheet, MADA3KP26AE3 pinout, MADA3KP26AE3 application, or MADA3KP26AE3 equivalent, this page delivers verified electrical parameters, package dimensions, IEC-compliant surge performance data, polarity marking convention, and RoHS-compliant sourcing details - all specific to the MADA3KP26AE3 variant.
Technical Context
The MADA3KP26AE3 is a single-channel unidirectional TVS diode optimized for fast clamping of high-energy transients with <100 ps response time. Its 3000 W peak pulse power rating at 10/1000 µs waveform and 2 µA max standby current at 26 V ensure minimal leakage during normal operation while delivering robust overvoltage suppression.
It uses a void-free thermosetting epoxy package rated UL94V-0, with tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026. Pin 1 is cathode-marked by a dot on top, and polarity follows odd-pin cathode convention per device layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ26A | 600 W PPP rating, same VWM and VC, DO-214AA (SMB) package | Limited to lower-energy transients; unsuitable for IEC61000-4-5 Class 3/4 testing | Select SMBJ26A only where surge threat level is restricted to ESD/EFT or low-duty-cycle switching noise. |
| 1.5KE27A | 1500 W PPP, axial-leaded DO-201AD package, higher V(BR) tolerance (±10%) | Not surface-mount; requires through-hole assembly and larger PCB area | Choose 1.5KE27A if legacy through-hole design or manual repair constraints prohibit SMC footprint adoption. |
Compared with SMBJ26A and 1.5KE27A, the MADA3KP26AE3 uniquely delivers 3000 W surge capacity in a compact SMC package with guaranteed low-leakage performance and MIL-PRF-19500 upscreening eligibility - making it the only option qualified for high-energy, high-reliability surface-mount deployments.

FAQ
What is the clamping voltage of the MADA3KP26AE3 at its rated peak pulse current?
The MADA3KP26AE3 has a maximum clamping voltage (VC) of 42.1 V at its rated peak pulse current (IPP) of 71.2 A under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in the RF01243 datasheet and guarantees that downstream components experience no more than 42.1 V during worst-case surge events. The MADA3KP26AE3 maintains this clamping performance across its full operating temperature range.
Is the MADA3KP26AE3 RoHS compliant, and what does the 'e3' suffix indicate?
Yes, the MADA3KP26AE3 is RoHS compliant. The 'e3' suffix explicitly denotes matte-tin plating in accordance with EU Directive 2011/65/EU, replacing lead-based terminations while maintaining solderability per MIL-STD-750 Method 2026. This compliance is confirmed in the part nomenclature section on Page 2 of the RF01243 datasheet and applies to all production lots shipped with the e3 designation.
How does the MADA3KP26AE3 differ from bidirectional variants like MADA3KP26CE3?
The MADA3KP26AE3 is unidirectional, meaning it conducts only during positive voltage excursions above its breakdown threshold, with Pin 1 as cathode. In contrast, MADA3KP26CE3 is bidirectional and clamps both polarities symmetrically. This makes the MADA3KP26AE3 ideal for DC-biased applications such as 24 V power rails, whereas the 'C' version suits AC-coupled or floating signal lines where polarity reversal may occur.
Can the MADA3KP26AE3 be used for IEC61000-4-5 Class 4 lightning surge testing?
Yes, the MADA3KP26AE3 is rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, as confirmed in the Applications/Benefits section on Page 1 of RF01243. Its 3000 W peak pulse power and 71.2 A IPP meet the 4 kV open-circuit voltage requirement. However, Class 4 with 2 Ω source impedance is not supported - that requires MADA3KP26AE3's lower-voltage siblings (e.g., MADA3KP9.0AE3).
What is the thermal derating behavior of the MADA3KP26AE3 above 25 °C ambient?
The MADA3KP26AE3 follows the derating curve shown in Figure 3 of RF01243: its peak pulse power decreases linearly from 100% at 25 °C to approximately 50% at 125 °C junction temperature. Since the device is rated for TJ up to +150 °C, designers must calculate actual junction temperature using thermal resistance and power dissipation to ensure sustained 3000 W capability is maintained only within the specified derating envelope.
