Product details
Overview
MDA3KP13CAE3 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 13 V reverse standoff voltage (VWM), 14.4–15.9 V breakdown voltage (V(BR)), 21.5 V maximum clamping voltage at 139.4 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 MDA3KP13CAE3 datasheet, MDA3KP13CAE3 pinout, MDA3KP13CAE3 application, or MDA3KP13CAE3 equivalent, key selection criteria include bidirectional polarity, 10/1000 µs surge rating, IEC61000-4-2/4-4/4-5 compliance, RoHS-compliant e3 termination, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MDA3KP13CAE3 is a monolithic TVS array with two symmetrical avalanche diodes in series opposition, enabling bidirectional clamping without external polarity constraints. Its sub-5 ns response time and <100 ps junction turn-on ensure effective suppression of ESD (±15 kV contact), EFT (±2 kV), and 42 Ω source impedance IEC61000-4-5 Class 1–4 transients.
It uses void-free UL94V-0 epoxy packaging with tin-lead or matte-tin plating per MIL-STD-750 Method 2026, and supports traceable wafer/assembly lot tracking. Standby current ID is ≤5 µA at 13 V, and thermal derating begins above 25 °C per Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous operating voltage before clamping activation |
| V(BR) min/max | 14.4–15.9 V @ 1 mA - ensures reliable avalanche initiation across temperature and process variation |
| VC @ IPP | 21.5 V @ 139.4 A - limits downstream circuit voltage during 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - defines peak energy handling capability under standardized surge waveform |
| ID @ VWM | ≤5 µA - guarantees minimal leakage in standby, critical for low-power sensor interfaces |

Pinout & Package
MDA3KP13CAE3 is housed in a surface-mount, 2-pin DO-214AB (SMC) package with cathode-defined pin 1 marked by a dot on the top surface. Terminals are tin-lead or matte-tin plated per MIL-STD-750 Method 2026, supporting reflow soldering at 260 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of first diode | Defines polarity reference; used with Pin 2 to form bidirectional clamping path |
| Pin 2 | Cathode of second diode | Completes symmetrical anti-series configuration for bidirectional transient conduction |
Key Features

| RoHS-compliant e3 marking | Confirms lead-free matte-tin termination compatible with Pb-free assembly processes and environmental compliance |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing overhead |
Applications
| Telecom Power Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protects 48 V DC power feeds in remote radio units against induced surges from nearby lightning strikes. IC Role / Device Role / Timing Role: Bidirectional TVS array clamps common-mode transients between power and ground while maintaining steady-state operation. Use Value: Limits voltage excursion to ≤21.5 V during 139.4 A 10/1000 µs surge, preserving downstream DC-DC converter input stage integrity. | Use Scenario: Shields 0–10 V analog inputs on programmable logic controllers from EFT bursts during factory floor switching events. IC Role / Device Role / Timing Role: Fast-response TVS absorbs repetitive 5 kHz EFT bursts per IEC61000-4-4 without degradation. Use Value: Sub-5 ns response and ≤5 µA leakage prevent signal offset drift and measurement error in precision acquisition circuits. |
| Automotive Body Control Module (BCM) CAN Bus Protection | Medical Patient Monitor ESD Shielding |

IC Role / Device Role / Timing Role: Bidirectional clamping protects differential CANH/CANL lines against asymmetrical transients without disrupting bus biasing. Use Value: 13 V VWM aligns with 12 V automotive nominal supply, allowing direct placement at connector entry point with no series impedance needed. | Use Scenario: Guards front-panel touch sensors and ECG electrode inputs against ±15 kV contact ESD per IEC61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance TVS array suppresses ESD without distorting high-impedance biopotential signals. Use Value: 21.5 V clamping voltage prevents latch-up in front-end amplifiers while maintaining signal fidelity below 100 kHz bandwidth. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package | Lower surge capacity suits consumer-grade I/O; insufficient for IEC61000-4-5 Class 4 | Select when cost-sensitive designs require basic ESD/EFT protection without secondary lightning compliance |
| 1.5KE13CA | 1500 W PPP, axial-leaded DO-15 package, higher leakage (≤10 µA) | Through-hole mounting only; not suitable for automated SMT production or space-constrained layouts | Choose for legacy board refreshes where footprint compatibility and manual assembly are prioritized over surge margin |
Compared with SMBJ13CA and 1.5KE13CA, the MDA3KP13CAE3 delivers double the surge power handling of the SMBJ variant and enables surface-mount scalability absent in the axial 1.5KE series - making it the sole option among the three qualified for MIL-PRF-19500 upscreening and Class 4 lightning immunity in compact industrial modules.

FAQ
What is the clamping voltage of MDA3KP13CAE3 at its rated peak pulse current?
The MDA3KP13CAE3 has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPP) of 139.4 A under 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and ensures downstream circuitry remains within safe voltage limits during surge events. The MDA3KP13CAE3 achieves this performance using a tightly controlled avalanche breakdown characteristic with V(BR) specified between 14.4 V and 15.9 V at 1 mA.
Is MDA3KP13CAE3 compliant with RoHS and what does the 'e3' suffix indicate?
The 'e3' suffix in MDA3KP13CAE3 confirms RoHS compliance per Directive 2011/65/EU, indicating matte-tin termination with lead content below threshold limits. This plating meets MIL-STD-750 Method 2026 for solderability and supports Pb-free reflow profiles up to 260 °C for 10 seconds. The MDA3KP13CAE3 is fully compatible with modern environmentally regulated manufacturing without requiring exemption documentation.
Can MDA3KP13CAE3 be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MDA3KP13CAE3 is validated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as documented in the RF01243 datasheet. Its 3000 W peak pulse power rating and 21.5 V clamping voltage at 139.4 A enable compliance when placed at equipment ports. The MDA3KP13CAE3 must be applied with appropriate PCB layout (short traces, low-inductance grounding) to maintain performance under 42 Ω coupling network conditions.
What is the standoff voltage and how does it relate to system operating voltage for MDA3KP13CAE3?
The MDA3KP13CAE3 has a reverse standoff voltage (VWM) of 13 V - the maximum continuous DC or RMS voltage that can be applied without triggering clamping. For reliable operation, system operating voltage must be ≤ VWM; for example, it is suited for 12 V nominal automotive or industrial systems. Exceeding 13 V risks premature conduction and accelerated wear. The MDA3KP13CAE3's V(BR) starts at 14.4 V, providing a defined margin above VWM.
Does MDA3KP13CAE3 support high-reliability screening per MIL-PRF-19500?
Yes, MDA3KP13CAE3 supports optional upscreening per MIL-PRF-19500, including wafer and assembly lot traceability, 3σ screening on standby current (ID), and conformance inspections. This capability is explicitly stated in the RF01243 datasheet and distinguishes the MDA3KP13CAE3 from commercial-grade TVS devices. Customers requiring MIL-PRF-19500 qualification must specify screening level at order time - the base MDA3KP13CAE3 is un-screened but fully compatible with the upscreening flow.
