Product details
Overview
MADA3KP15CA from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning and ESD protection. It features a 15 V standoff voltage (VWM), 16.7–18.5 V breakdown range (V(BR)), 24.4 V maximum clamping voltage at 123 A peak pulse current, and operates from –55 °C to +150 °C - deployed in telecom power interfaces and industrial I/O protection circuits.
For engineers reviewing the MADA3KP15CA datasheet, MADA3KP15CA pinout, MADA3KP15CA application, or MADA3KP15CA equivalent, key selection criteria include bidirectional polarity, IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω source impedances, 100 ps response time, and RoHS-compliant e3 marking - all critical for robust surge immunity in harsh-environment electronics.
Technical Context
The MADA3KP15CA is a monolithic TVS array built using silicon avalanche technology, optimized for fast transient suppression without degradation under repeated 10/1000 µs surges. Its bidirectional construction enables symmetrical clamping across both polarities, supporting AC-coupled signal lines and ungrounded bus protection.
It meets MIL-PRF-19500 screening options for high-reliability applications and delivers full 3000 W peak pulse power capability at 25 °C, with derating above 25 °C per Figure 3. Standby leakage is limited to ≤2 µA at 15 V, ensuring minimal impact on system bias integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - Maximum continuous operating voltage before conduction begins; sets minimum system voltage margin for reliable standby operation. |
| V(BR) min/max | 16.7–18.5 V @ 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients without premature triggering. |
| VC @ IPP | 24.4 V @ 123 A - Clamping voltage under 10/1000 µs surge; defines worst-case overvoltage seen by protected downstream circuitry. |
| PPP | 3000 W @ 10/1000 µs - Peak surge energy handling capacity; supports IEC61000-4-5 Level 4 testing with 42 Ω source impedance. |
| ID @ VWM | ≤2 µA - Ultra-low leakage at rated standoff; avoids loading of high-impedance sensor or reference circuits. |
| Response time | <5 ns - Sub-nanosecond turn-on latency; captures ESD events (IEC61000-4-2) before damage occurs. |
| TJ/TSTG | –55 °C to +150 °C - Extended thermal range enables use in automotive engine bays and industrial motor drives. |
Pinout & Package
Package: Surface-mount DO-214AB (SMC) with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity defined by dot marking indicating Pin 1 (cathode for each TVS element). Weight ≈5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (TVS1) | Reference terminal for first bidirectional TVS junction; connects to protected line or ground depending on 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 |
|---|---|---|---|
| SMBJ15CA | 600 W PPP rating, same VWM and bidirectional polarity, but lower clamping voltage (24.4 V vs. 24.4 V identical) and smaller SMC package footprint. | Targeted at space-constrained consumer electronics; lacks MIL-PRF-19500 screening and 3000 W surge capability. | Select SMBJ15CA only when surge threat level is ≤1 kV and board area is critical. |
| 1.5KE15CA | 3000 W PPP, axial-leaded DO-201 package, higher thermal resistance, no surface-mount compatibility. | Used in legacy through-hole designs; incompatible with automated SMT assembly and high-density layouts. | Choose 1.5KE15CA only for repair or retrofit of existing through-hole boards where rework is acceptable. |
Compared with SMBJ15CA and 1.5KE15CA, the MADA3KP15CA uniquely combines 3000 W surge handling, surface-mount DO-214AB packaging, MIL-PRF-19500 upscreening eligibility, and verified IEC61000-4-5 Class 4 compliance - making it the sole choice for new high-reliability industrial and transportation designs requiring zero-layout compromise.

FAQ
What is the polarity configuration of the MADA3KP15CA?
The MADA3KP15CA is a bidirectional TVS device, indicated by the "C" suffix in its part number. It provides symmetrical clamping for both positive and negative transients across its terminals, making it ideal for protecting AC-coupled lines, differential buses like RS-485, and ungrounded signal paths without polarity concerns. This behavior is confirmed in the "Part Nomenclature" section of the RF01243 datasheet.
Does the MADA3KP15CA meet IEC61000-4-5 Class 4 requirements?
Yes, the MADA3KP15CA is rated for IEC61000-4-5 Class 4 secondary lightning protection with a 42 Ω source impedance, delivering full 3000 W surge capability at 25 °C. The datasheet explicitly lists MDA3KP15CA (and MDA3KP15CA variants) in the Class 1–4 group for 42 Ω testing, and confirms compliance via standardized 10/1000 µs waveform testing per Figure 1 and Table on page 3.
What is the maximum clamping voltage of the MADA3KP15CA and at what current is it specified?
The MADA3KP15CA has a maximum clamping voltage (VC) of 24.4 V, measured at its peak pulse current (IPP) of 123 A under 10/1000 µs waveform conditions. This value is specified in the Electrical Characteristics table on page 3 of the RF01243 datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Is the MADA3KP15CA RoHS compliant and what does the "e3" marking indicate?
Yes, the MADA3KP15CA is RoHS compliant, as indicated by the "e3" suffix in its full marking per the "Part Nomenclature" diagram on page 2. The "e3" designation confirms lead-free matte-tin plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity requirements - eliminating need for dry packing and enabling standard Pb-free reflow profiles.
Can the MADA3KP15CA be used in automotive applications subject to ISO 7637-2 load dump?
The MADA3KP15CA is suitable for certain automotive applications including body control module (BCM) power bus protection, as its 24.4 V clamping voltage and 3000 W rating provide margin against ISO 7637-2 Pulse 5a (load dump) transients when combined with upstream impedance. While not AEC-Q200 qualified out-of-box, its –55 °C to +150 °C operating range and MIL-PRF-19500 upscreening options support qualification-ready use in non-safety-critical 12 V systems.
