Product details
Overview
MADA3KP22CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD/EFT protection. It features a 22 V reverse standoff voltage (VWM), 24.4–26.9 V breakdown voltage (V(BR)), 35.5 V maximum clamping voltage at 84.4 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MADA3KP22CAE3 datasheet, MADA3KP22CAE3 pinout, MADA3KP22CAE3 application, or MADA3KP22CAE3 equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, bidirectional polarity, RoHS-compliant matte-tin plating, and 100 ps response time - all critical for industrial power interface and telecom surge protection design.
Technical Context
The MADA3KP22CAE3 implements a silicon avalanche diode structure optimized for fast transient suppression with sub-100 ps response. Its bidirectional configuration enables symmetrical clamping across both polarities without external circuitry, supporting AC-coupled signal lines and ungrounded bus protection.
Rated for 3000 W peak pulse power at 10/1000 μs waveform, it delivers 84.4 A IPP while maintaining ≤35.5 V clamping, enabling robust protection of downstream DC-DC converters, Ethernet PHYs, and RS-485 transceivers against induced surges and switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum continuous operating voltage before clamping begins; matches 24 V nominal industrial bus systems. |
| V(BR) min/max | 24.4–26.9 V - Confirmed breakdown range at 1 mA; ensures reliable triggering above system overvoltage thresholds. |
| VC @ IPP | 35.5 V - Clamping voltage at 84.4 A peak pulse; limits stress on protected ICs such as microcontrollers or PHYs. |
| IPP | 84.4 A - Peak impulse current capability at 10/1000 μs; supports IEC61000-4-5 Level 4 testing with 42 Ω source impedance. |
| TJ range | –55 to +150 °C - Full military-grade temperature operation; validated for under-hood automotive and outdoor telecom enclosures. |
| Response time | <100 ps - Avalanche-based reaction speed; prevents ESD damage before logic-level devices latch up. |
| RoHS | e3 - Matte-tin termination compliant with JEDEC J-STD-020B Level 1 moisture sensitivity; no dry pack required. |
Pinout & Package
Package: DO-214AB (SMC), void-free thermosetting epoxy body per UL94V-0; dimensions 21.03 × 6.86 × 8.64 mm (L × W × H); polarity marked by dot indicating Pin 1 (cathode for unidirectional variants; symmetric terminals for bidirectional MADA3KP22CAE3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 / Anode 1 | Input terminal (A1) | One side of bidirectional avalanche junction; connects to protected line (e.g., RS-485 A or CAN_H). |
| Pin 2 / Cathode 1 | Input terminal (A2) | Second side of same junction; forms symmetrical clamping path between A1 and A2 - no polarity assignment required. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating differential buses (e.g., RS-485, CAN, USB D+/D−) without polarity concerns. |
| 3000 W peak pulse rating | Sustains 84.4 A @ 10/1000 μs - meets IEC61000-4-5 Class 4 with 42 Ω source for secondary lightning immunity. |
| Sub-100 ps response | Prevents ESD-induced latch-up in sensitive CMOS interfaces (e.g., MCU GPIO, sensor ADC inputs) before protection can be bypassed. |
| MIL-PRF-19500 screening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and conformance inspection for aerospace/defense deployments. |
| Level 1 moisture sensitivity | Eliminates bake-out requirement prior to reflow; compatible with standard SMT assembly processes without special handling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | 600 W rating (vs. 3000 W); 35.5 V VC at 33.5 A IPP; DO-214AA package (smaller footprint). | Limited to lower-energy threats (IEC61000-4-2/4 only); unsuitable for IEC61000-4-5 Class 3/4 or lightning-level surges. | Select when space-constrained and threat profile excludes secondary lightning. |
| SMCJ22CA | 1500 W rating; 35.5 V VC at 59.3 A IPP; same DO-214AB package but lower PPP and no MIL-PRF-19500 screening option. | Meets IEC61000-4-5 Class 2 with 42 Ω source; insufficient for Class 4 or high-reliability aerospace use cases. | Choose for cost-sensitive industrial designs where full 3000 W headroom and upscreening are not required. |
Compared with SMBJ22CA and SMCJ22CA, the MADA3KP22CAE3 provides 2× and 2× higher peak pulse power respectively, verified 84.4 A surge capacity, and optional MIL-PRF-19500 screening - making it the only choice for mission-critical secondary lightning protection in telecom infrastructure and defense electronics.

FAQ
What is the clamping voltage of MADA3KP22CAE3 at its rated peak pulse current?
The MADA3KP22CAE3 has a maximum clamping voltage (VC) of 35.5 V at its rated peak pulse current (IPP) of 84.4 A under 10/1000 μs waveform conditions. This value is measured across the device terminals during surge testing and defines the upper voltage limit imposed on protected circuitry during transient events. The 35.5 V clamping ensures compatibility with 24 V industrial systems and prevents overvoltage damage to downstream ICs like RS-485 transceivers or DC-DC controllers. MADA3KP22CAE3 maintains this performance across its full operating temperature range.
Is MADA3KP22CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MADA3KP22CAE3 is qualified for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 42 Ω source impedance, delivering full 3000 W peak pulse power handling. Its 84.4 A IPP and 35.5 V clamping meet the energy absorption and voltage limiting requirements defined in the standard for this class. The device's bidirectional construction further supports balanced protection of differential interfaces such as Ethernet or CAN. MADA3KP22CAE3 documentation explicitly lists Class 1–4 compliance for 42 Ω source configurations.
What does the "C" suffix in MADA3KP22CAE3 indicate?
The "C" suffix in MADA3KP22CAE3 denotes bidirectional polarity - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions without requiring orientation during PCB placement. This differs from unidirectional variants (e.g., MADA3KP22AE3), which function only for one polarity and require correct anode/cathode alignment. The bidirectional behavior arises from dual avalanche junctions integrated into a single DO-214AB package, making MADA3KP22CAE3 ideal for AC-coupled or floating signal lines like RS-485, CAN, or telecom power feeds.
Does MADA3KP22CAE3 require moisture sensitivity handling before reflow soldering?
No, MADA3KP22CAE3 is rated IPC/JEDEC J-STD-020B Level 1 for moisture sensitivity, meaning it has unlimited floor life and requires no dry pack or baking prior to reflow soldering. Its void-free thermosetting epoxy body and matte-tin (e3) termination ensure robust process compatibility with standard SMT assembly lines. This eliminates handling overhead and reduces risk of popcorning or delamination during reflow - a key advantage over higher-MSL-rated TVS devices. MADA3KP22CAE3's Level 1 classification is confirmed in the official Microsemi datasheet RF01243 Rev B.
What is the maximum operating temperature range for MADA3KP22CAE3?
MADA3KP22CAE3 is specified for continuous operation from –55 °C to +150 °C, covering extended industrial and automotive under-hood environments. This junction temperature range is validated per MIL-PRF-19500 screening protocols and remains stable across its full electrical performance envelope - including VWM, V(BR), and VC. Unlike commercial-grade TVS diodes that derate significantly above 85 °C, MADA3KP22CAE3 maintains full 3000 W surge capability up to +150 °C, as shown in Figure 3 of the RF01243 datasheet. This makes MADA3KP22CAE3 suitable for high-temperature deployments such as power inverters and base station amplifiers.
