Product details
Overview
MDA3KP24CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, featuring 24 V standoff voltage (VWM), 26.7–29.5 V breakdown voltage (V(BR)), 38.9 V maximum clamping voltage (VC) at 77.2 A peak pulse current, and <5 ns response time - deployed for secondary lightning protection in telecom power interfaces and industrial I/O circuits.
For engineers reviewing the MDA3KP24CAE3 datasheet, MDA3KP24CAE3 pinout, MDA3KP24CAE3 application, or MDA3KP24CAE3 equivalent, key selection criteria include bidirectional surge handling per IEC61000-4-5 (42 Ω/12 Ω source), RoHS-compliant matte-tin plating, MIL-PRF-19500 upscreening eligibility, and thermal derating above 25 °C per Figure 3.
Technical Context
This TVS array operates as a voltage-clamped shunt protector: when transient voltage exceeds V(BR), it avalanches into low-impedance conduction to divert surge energy away from downstream circuitry. Its bidirectional construction enables symmetric clamping for AC-coupled or floating signal lines without polarity constraints.
Rated for 3000 W peak pulse power at 10/1000 µs waveform, it sustains 77.2 A IPP while maintaining VC ≤ 38.9 V, with standby leakage ID ≤ 2 µA at 24 V and junction temperature range of –55 °C to +150 °C - validated under MIL-PRF-19500 screening options for high-reliability aerospace and defense systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - maximum continuous operating voltage before clamping begins; matches 24 V DC power rails or AC peak voltages. |
| V(BR) min/max | 26.7–29.5 V - guaranteed avalanche onset window; ensures reliable triggering above normal operating transients. |
| VC @ IPP | 38.9 V at 77.2 A - clamping voltage during worst-case 10/1000 µs surge; protects 3.3 V/5 V logic behind series impedance. |
| PPP | 3000 W - peak pulse power rating at 10/1000 µs; supports Class 3/4 secondary lightning per IEC61000-4-5 with 12 Ω source. |
| Response time | <5 ns - time from 0 V to V(BR) min; fast enough to suppress ESD (IEC61000-4-2) and EFT (IEC61000-4-4). |
| ID @ VWM | ≤2 µA - ultra-low leakage at rated standoff; avoids loading sensitive analog or battery-backed circuits. |
| TJ/TSTG | –55 °C to +150 °C - extended thermal range enables use in under-hood automotive or outdoor industrial enclosures. |
Pinout & Package
MDA3KP24CAE3 uses a DO-214AB (SMC) plastic package with void-free UL94V-0 epoxy body, matte-tin-plated terminals, and polarity defined by a dot marking indicating Pin 1 (cathode for unidirectional variants; symmetrical for bidirectional MDA3KP24CAE3). Weight ≈ 5 g; dimensions per RF01243 Rev B Page 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode Pair | Bidirectional clamping node | Two-terminal device with symmetrical avalanche behavior - connects across protected line and return (e.g., RS-485 A/B, Ethernet pairs). |
| Case | Non-electrical mechanical reference | Plastic body provides insulation; no thermal or electrical connection - mounting requires thermal relief but no grounding tie. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | 600 W PPP rating, same VWM and bidirectional configuration, DO-214AA package (smaller footprint). | Limited to Class 2 lightning (IEC61000-4-5, 42 Ω); insufficient for Class 4 telecom or industrial mains-coupled surges. | Select when space-constrained and surge threat level is ≤600 W - verify clamping margin against downstream IC abs max ratings. |
| 1.5KE24CA | 1500 W PPP, axial-leaded DO-15 package, higher leakage (ID ≤ 5 µA), slower thermal recovery. | Not suitable for automated SMT assembly; requires through-hole rework and lacks MIL-PRF-19500 screening path. | Choose only for legacy through-hole designs or prototyping where reflow compatibility and high-reliability screening are not required. |

FAQ
What is the clamping voltage of MDA3KP24CAE3 at its rated peak pulse current?
MDA3KP24CAE3 has a maximum clamping voltage (VC) of 38.9 V at 77.2 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is measured per standard test methods and guarantees protection margin for downstream 24 V-rated components. The clamping performance remains stable across the full operating temperature range of –55 °C to +150 °C, as confirmed in the MDA3KP24CAE3 datasheet Figure 2.
Is MDA3KP24CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MDA3KP24CAE3 is rated for IEC61000-4-5 Class 4 secondary lightning protection with a 42 Ω source impedance, delivering 3000 W peak pulse power. It also supports Class 3 with 12 Ω source and Class 2 with 2 Ω source per the manufacturer's application guidance. Its bidirectional architecture and <5 ns response ensure effective suppression of fast-rising lightning-induced transients on AC or DC lines.
Does MDA3KP24CAE3 require dry packing or baking before SMT reflow?
No, MDA3KP24CAE3 has IPC/JEDEC J-STD-020B moisture sensitivity Level 1, meaning it can be stored indefinitely at ambient conditions and placed directly into reflow without dry pack or pre-bake. This eliminates handling steps and reduces risk of moisture-related popcorning during soldering - a key advantage over Level 3+ TVS devices in high-volume manufacturing.
What does the "C" and "e3" suffix mean in MDA3KP24CAE3?
In MDA3KP24CAE3, "C" denotes bidirectional polarity, enabling symmetric clamping for AC or floating differential signals. "e3" indicates RoHS-compliant matte-tin terminal plating per JEDEC J-STD-609, verified for lead-free soldering up to 260 °C for 10 seconds. Both suffixes are defined in the part nomenclature section of the RF01243 datasheet.
Can MDA3KP24CAE3 be used in automotive under-hood applications?
Yes, MDA3KP24CAE3 supports junction temperatures from –55 °C to +150 °C and is qualified for high-reliability operation in demanding environments. Its thermal derating curve (Figure 3 in RF01243) confirms usable pulse power at elevated ambient temperatures, making it suitable for automotive body control modules, battery management inputs, and other under-hood locations where transient immunity and thermal resilience are critical.
