Product details
Overview
MDA3KP11CAE3 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 protection. It features a 11 V reverse standoff voltage (VWM), 12.2–13.5 V breakdown voltage (V(BR)), 18.2 V maximum clamping voltage at 164.8 A peak pulse current, and operates from –55 °C to +150 °C - used in telecom power interfaces and industrial I/O protection.
For engineers reviewing the MDA3KP11CAE3 datasheet, MDA3KP11CAE3 pinout, MDA3KP11CAE3 application, or MDA3KP11CAE3 equivalent, key selection criteria include bidirectional surge handling per IEC61000-4-5 (Class 1–4, 42 Ω/12 Ω/2 Ω source), 100 ps response time, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility.
Technical Context
This TVS array uses silicon avalanche diode technology with symmetrical bidirectional conduction, enabling clamping of both positive and negative transients without polarity constraints. Its 3000 W peak pulse power rating (10/1000 µs waveform) and sub-100 ps response ensure effective suppression of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and induced lightning surges.
The device implements a two-terminal configuration with cathodes on odd-numbered pins (Pin 1 and Pin 3), validated for vertical mounting in high-density PCB layouts. Standby leakage remains ≤5 µA at 11 V VWM, supporting low-power system monitoring while maintaining robust surge immunity across –55 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - Maximum continuous operating voltage before clamping begins; matches 12 V rail systems with margin. |
| V(BR) min/max | 12.2–13.5 V - Confirmed avalanche onset range at 1 mA; ensures predictable turn-on under fast transients. |
| VC @ IPP | 18.2 V at 164.8 A - Clamping voltage during worst-case 10/1000 µs surge; protects downstream ICs rated ≥16 V. |
| PPP | 3000 W - Peak pulse power handling per IEC61000-4-5; supports Class 4 lightning with 42 Ω source impedance. |
| TJ range | –55 °C to +150 °C - Extended thermal operation enables use in automotive engine bays and industrial enclosures. |
| ID @ VWM | ≤5 µA - Ultra-low leakage preserves battery life in always-on monitoring circuits. |
| Response time | <100 ps - Near-instantaneous avalanche triggering prevents voltage overshoot beyond protected IC limits. |
Pinout & Package
MDA3KP11CAE3 is housed in a DO-214AB (SMC) plastic package with void-free UL94V-0 epoxy body, matte-tin-plated terminals, and polarity marked by a dot indicating Pin 1 (cathode). Weight ≈5 g; moisture sensitivity level = 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Bidirectional) | Common cathode terminal for symmetrical clamping; connects to protected line in differential or single-ended configurations. |
| Pin 2 | Anode (Bidirectional) | Common anode terminal; forms dual-junction path enabling equal clamping for ± transients. |
| Pin 3 | Cathode (Bidirectional) | Second cathode terminal - paired with Pin 1 to define the two-terminal device; odd pins are cathodes per datasheet polarity rule. |
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 |
|---|---|---|---|
| SMBJ11CA | 600 W PPP rating (vs. 3000 W); same VWM and bidirectional polarity; DO-214AA package. | Not suitable for IEC61000-4-5 Class 4; limited to ESD/EFT and low-energy switching transients. | Select when space-constrained layouts require smaller footprint and surge energy is ≤600 W. |
| 1.5KE11CA | 3000 W PPP but axial-leaded DO-201AD package; higher thermal resistance; no MIL-PRF-19500 screening option. | Requires through-hole mounting; incompatible with automated SMT assembly; unsuitable for high-vibration environments. | Choose only for legacy through-hole designs where rework to SMT is impractical. |
Compared with SMBJ11CA and 1.5KE11CA, MDA3KP11CAE3 delivers 5× higher surge capacity in an SMT package with military-grade screening support, making it optimal for new industrial and telecom designs demanding Class 4 lightning immunity and production scalability.

FAQ
What is the clamping voltage of MDA3KP11CAE3 at its rated peak pulse current?
The MDA3KP11CAE3 has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPP) of 164.8 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MDA3KP11CAE3 maintains this clamping performance across its full operating temperature range.
Is MDA3KP11CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MDA3KP11CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with a 42 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power rating and 18.2 V clamping voltage ensure compliance when applied per standard test configuration. The MDA3KP11CAE3 also supports Class 4 with 12 Ω and 2 Ω source impedances depending on voltage grade.
What does the 'C' suffix in MDA3KP11CAE3 indicate?
The 'C' suffix in MDA3KP11CAE3 denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients across its two terminals. This is distinct from unidirectional variants (e.g., MDA3KP11AE3) which clamp only one polarity. The MDA3KP11CAE3 uses this configuration to protect AC-coupled lines or floating DC buses without requiring external polarity management.
Does MDA3KP11CAE3 require dry packing per J-STD-020B?
No, MDA3KP11CAE3 has a moisture sensitivity level (MSL) of 1 per IPC/JEDEC J-STD-020B, meaning it is not moisture-sensitive and does not require dry packing or baking prior to reflow soldering. This simplifies manufacturing handling and eliminates yield loss risks associated with moisture-related popcorning. The MDA3KP11CAE3's thermosetting epoxy body contributes to this robust MSL rating.
Can MDA3KP11CAE3 be used in automotive under-hood applications?
Yes, MDA3KP11CAE3 supports junction temperatures from –55 °C to +150 °C and is qualified for high-reliability environments, making it suitable for automotive under-hood applications such as body control modules and sensor power conditioning. Its low standby current (≤5 µA at 11 V) and MIL-PRF-19500 upscreening option further validate its use in demanding automotive deployments. The MDA3KP11CAE3 meets these requirements without derating in most engine bay thermal profiles.
