Product details
Overview
MADA3KP15CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability surge protection of DC power rails and signal lines. It features a 15 V standoff voltage (VWM), 16.7–18.5 V breakdown range (V(BR)), 24.4 V max clamping voltage at 123 A peak pulse current, and operates from −55 °C to +150 °C - used in industrial power supplies and telecom interface protection.
For engineers reviewing the MADA3KP15CAE3 datasheet, MADA3KP15CAE3 pinout, MADA3KP15CAE3 application, or MADA3KP15CAE3 equivalent, key selection criteria include bidirectional IEC61000-4-5 Class 1–4 secondary lightning compliance, 10/1000 µs surge rating, RoHS-compliant e3 termination, and polarity-defined pin 1 marking for PCB layout verification.
Technical Context
MADA3KP15CAE3 implements a silicon avalanche diode structure optimized for sub-nanosecond response to transients, with clamping action triggered at ≥16.7 V (V(BR) min) and limiting voltage to ≤24.4 V at 123 A IPP under 10/1000 µs waveform. Its bidirectional configuration enables symmetrical protection on AC-coupled or floating lines without polarity concerns.
The device meets MIL-PRF-19500 screening options for high-reliability programs and is surge-tested per JEDEC JESD22-A114 (ESD), JESD22-A115 (EFT), and IEC61000-4-5 (lightning) - with derating applied above 25 °C per Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 16.7–18.5 V @ 1 mA - ensures reliable turn-on before downstream IC damage thresholds |
| VC @ IPP | 24.4 V @ 123 A - limits transient voltage seen by protected circuit during 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - defines energy-handling capability for lightning and switching surges |
| ID @ VWM | 2 µA max - negligible leakage at rated standoff, preserving low-power system efficiency |
| TJ/TSTG | −55 °C to +150 °C - supports operation in harsh environments including automotive under-hood and industrial motor drives |
Pinout & Package
Package: Surface-mount DO-214AB (SMC) molded epoxy case, void-free UL94V-0 compliant, 5 g weight, with matte-tin (e3) plating and dot-marked pin 1. Polarity: odd-numbered pins are cathodes; MADA3KP15CAE3 is a dual-anode/dual-cathode bidirectional array in a 2-pin configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional terminal) | Marked by dot; connects to protected line side - forms symmetrical clamping path with Pin 2 |
| Pin 2 | Cathode (Bidirectional terminal) | Unmarked end; completes bidirectional path - no anode connection required for AC or floating rail use |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals or ungrounded DC buses without external polarity management |
| 3000 W 10/1000 µs rating | Handles IEC61000-4-5 Class 4 surges (42 Ω source) up to 123 A peak without failure |
| RoHS-compliant e3 termination | Matte-tin plating ensures lead-free solder compatibility and eliminates Pb-related reliability concerns |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace, defense, and medical applications via wafer/lot traceability and 3σ ID screening |
Applications
| Industrial Power Supply Protection | Telecom Line Interface |
|---|---|
Use Scenario: 24 V DC input rail in programmable logic controller (PLC) power module exposed to relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed across input terminals to limit transients to <25 V before upstream DC-DC converter. Use Value: Prevents latch-up or gate oxide rupture in MOSFET-based input stage by clamping within 5 ns of surge onset. | Use Scenario: RS-485 data line pair in outdoor base station equipment subject to induced lightning currents. IC Role / Device Role / Timing Role: Bidirectional TVS connected between differential pair and ground to shunt common-mode surges. Use Value: Maintains signal integrity by limiting differential voltage excursion to <25 V while surviving 42 Ω IEC61000-4-5 Class 4 events. |
| Automotive Body Control Module | Medical Imaging Sensor Interface |
Use Scenario: 12 V battery-supplied window lift control circuit subjected to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Input-side TVS absorbing >3000 W spikes before linear regulator and microcontroller. Use Value: Eliminates need for series impedance or additional filtering due to sub-100 ps response and low clamping ratio. | Use Scenario: Analog front-end of ultrasound transducer array receiving low-level echo signals from human tissue. IC Role / Device Role / Timing Role: Signal-line protector on receive path to prevent ESD-induced amplifier saturation or ADC saturation. Use Value: Preserves dynamic range with only 2 µA standby leakage at 15 V, avoiding DC offset drift in precision amplifiers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | 600 W PPP rating, same VWM and bidirectional configuration, DO-214AA package | Lower surge capacity suits consumer-grade 12–24 V systems; not qualified for MIL-PRF-19500 screening | Select when cost sensitivity outweighs 3000 W requirement and high-reliability screening is unnecessary |
| 1.5KE15CA | 3000 W PPP but through-hole DO-15 package, higher thermal resistance, no e3 RoHS marking | Requires PCB rework for SMT transition; lacks moisture sensitivity level 1 classification per J-STD-020B | Choose only for legacy through-hole designs where board real estate and reflow compatibility are secondary |
Compared with SMBJ15CA and 1.5KE15CA, MADA3KP15CAE3 delivers higher surge robustness in a RoHS-compliant SMT package with military-grade traceability - making it optimal for new industrial and telecom designs requiring Class 4 lightning immunity and long-term supply continuity.

FAQ
What is the clamping voltage of MADA3KP15CAE3 at its rated peak pulse current?
MADA3KP15CAE3 has a maximum clamping voltage (VC) of 24.4 V at its rated peak pulse current (IPP) of 123 A under 10/1000 µs waveform conditions. This value is measured across the device terminals during standardized surge testing and defines the upper voltage limit imposed on protected circuits during worst-case transients.
Is MADA3KP15CAE3 compatible with lead-free reflow soldering processes?
Yes, MADA3KP15CAE3 features e3 matte-tin plating and is rated for solder temperatures up to 260 °C for 10 seconds, fully compliant with IPC/JEDEC J-STD-020B Level 1 moisture sensitivity. Its void-free thermosetting epoxy body ensures mechanical stability during standard lead-free reflow profiles.
Does MADA3KP15CAE3 meet IEC61000-4-5 Class 4 requirements?
Yes, MADA3KP15CAE3 is specified for secondary lightning protection per IEC61000-4-5 with 42 Ω source impedance up to Class 4, as confirmed in the Applications/Benefits section of RF01243 Rev B. Its 3000 W rating and 24.4 V clamping enable compliance when applied with appropriate PCB layout and grounding.
What does the "C" suffix in MADA3KP15CAE3 indicate?
The "C" suffix in MADA3KP15CAE3 denotes bidirectional construction - meaning the device provides symmetrical clamping for both positive and negative transients without polarity dependence. This differs from unidirectional variants (e.g., MADA3KP15AE3), which require correct orientation relative to DC bias.
How is polarity identified on the MADA3KP15CAE3 package?
Polarity is identified by a dot marking on the top surface of the DO-214AB package, designating Pin 1. Per the datasheet, odd-numbered pins are cathodes - so both Pin 1 and Pin 2 serve as cathodes in this bidirectional configuration, forming a symmetric clamping path between terminals.
