Product details
Overview
MADA3KP26CAE3 from Microsemi is a bidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in power rails and signal lines. It features a 26 V standoff voltage (VWM), 28.9–31.9 V breakdown range (V(BR)), 42.1 V clamping voltage at 71.2 A peak pulse current, and operates across –55 °C to +150 °C.
For engineers reviewing the MADA3KP26CAE3 datasheet, MADA3KP26CAE3 pinout, MADA3KP26CAE3 application, or MADA3KP26CAE3 equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, RoHS-compliant matte-tin plating, UL94V-0 epoxy package, and verified 100 ps response time for fast transient suppression.
Technical Context
The MADA3KP26CAE3 implements a bidirectional avalanche diode structure optimized for low-clamping, high-energy surge handling under 10/1000 µs waveform conditions. Its design supports dual-polarity transient suppression without external polarity management, enabling direct integration into AC-coupled or floating interfaces.
It meets MIL-PRF-19500 screening options for high-reliability applications and delivers full 3000 W peak pulse power rating at 25 °C with defined derating above 25 °C per Figure 3. Standby leakage remains ≤2 µA at 26 V, ensuring minimal impact on system quiescent power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 26 V - Maximum continuous working voltage before clamping begins; matches 24 V nominal rail systems with safety margin. |
| V(BR) min/max | 28.9–31.9 V - Verified breakdown threshold at 1 mA; ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 42.1 V - Clamping voltage at 71.2 A peak pulse; limits downstream voltage stress during 3000 W surges. |
| IPP | 71.2 A - Peak impulse current supported under 10/1000 µs waveform; defines maximum surge energy absorption. |
| ID @ VWM | ≤2 µA - Ultra-low standby leakage at rated standoff; avoids battery drain or signal integrity degradation. |
| TJ/TSTG | –55 to +150 °C - Extended temperature range enables use in automotive engine bays and industrial enclosures. |
| Response time | <100 ps - Sub-nanosecond turn-on guarantees protection against ESD (IEC61000-4-2) and EFT (IEC61000-4-4). |
Pinout & Package
Package: Void-free transfer-molded thermosetting epoxy case (UL94V-0), 5 g weight, matte-tin plated terminals solderable per MIL-STD-750 Method 2026. Pin 1 identified by dot marking; odd-numbered pins are cathodes per device polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line; clamps positive transients to ground when referenced to Pin 2. |
| Pin 2 | Anode of Channel 1 / Cathode of Channel 2 | Common node between two back-to-back TVS diodes; enables bidirectional clamping behavior. |
| Pin 3 | Anode of Channel 2 | Connected to ground or return path; completes bidirectional conduction path for negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Single-device AC-line or floating-bus protection without external polarity routing or dual-component layout. |
| 3000 W peak pulse power | Handles IEC61000-4-5 Class 4 surges (42 Ω source) without failure; validated per Figure 1 derating curve. |
| MIL-PRF-19500 screening option | Enables high-reliability deployment in aerospace, defense, and critical infrastructure with wafer/lot traceability. |
| Moisture sensitivity Level 1 | No dry-pack or baking required prior to reflow; simplifies manufacturing and reduces process risk. |
| RoHS-compliant (e3) | Meets EU Directive 2011/65/EU with annealed matte-tin plating; eliminates lead-based solder compatibility concerns. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ26CA | 600 W PPP rating, SMC package, 43.3 V VC @ 32.4 A IPP | Limited to lower-energy surges; unsuitable for IEC61000-4-5 Class 4 with 42 Ω source. | Select only for cost-sensitive, non-critical 24 V systems where full 3000 W capability is not required. |
| SMCJ26CA | 1500 W PPP rating, same SMC package footprint, 43.3 V VC @ 43.4 A IPP | Half the energy handling of MADA3KP26CAE3; requires parallel devices for equivalent Class 4 performance. | Use when board space constraints prevent larger MDA package but higher reliability than SMBJ is needed. |
Compared with SMBJ26CA and SMCJ26CA, the MADA3KP26CAE3 delivers double the surge energy capacity of SMCJ26CA and five times that of SMBJ26CA in the same functional category-enabling single-device compliance with stringent IEC61000-4-5 Class 4 testing without layout redesign or paralleling.

FAQ
What does the 'C' suffix in MADA3KP26CAE3 indicate?
The 'C' suffix in MADA3KP26CAE3 denotes bidirectional configuration-meaning the device contains two back-to-back avalanche diodes enabling symmetrical clamping for both positive and negative transients. This eliminates the need for polarity-aware placement and supports AC-coupled or floating interfaces. The MADA3KP26CAE3 achieves this in a single 3-pin package with Pin 2 as the common terminal.
Is MADA3KP26CAE3 compliant with IEC61000-4-5 Class 4 testing?
Yes, MADA3KP26CAE3 is rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as confirmed in the Applications/Benefits section of RF01243 Rev B. Its 3000 W peak pulse power and 42.1 V clamping voltage at 71.2 A ensure voltage limiting below system damage thresholds during standardized 4 kV surge tests.
What is the meaning of the 'e3' suffix in MADA3KP26CAE3?
The 'e3' suffix in MADA3KP26CAE3 indicates RoHS-compliant termination-specifically annealed matte-tin plating per JEDEC J-STD-020B. This ensures lead-free solder compatibility, eliminates hazardous substances per EU Directive 2011/65/EU, and supports standard reflow profiles without special processing.
Can MADA3KP26CAE3 replace unidirectional TVS devices like MDA3KP26AE3?
No-MADA3KP26CAE3 is not a drop-in replacement for unidirectional variants such as MDA3KP26AE3. While both share the same package and standoff voltage, the bidirectional 'C' version has different internal topology (dual-anode/cathode junction) and clamping symmetry. Substitution requires circuit review to confirm polarity tolerance and grounding scheme compatibility.
What is the maximum operating temperature for MADA3KP26CAE3?
MADA3KP26CAE3 is rated for junction and storage temperatures from –55 °C to +150 °C, as specified in the Maximum Ratings table on page 2 of RF01243 Rev B. Derating of peak pulse power begins above 25 °C per Figure 3, with 50% power capability retained at +100 °C ambient.
