Product details
Overview
MDA3KP40CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC61000-4-2, and EFT protection per IEC61000-4-4. It features a 40 V reverse standoff voltage (VWM), 44.4–49.1 V breakdown voltage (V(BR)), and clamps transients to ≤64.5 V at 46.4 A peak pulse current (IPP).
For engineers reviewing the MDA3KP40CAE3 datasheet, MDA3KP40CAE3 pinout, MDA3KP40CAE3 application, or MDA3KP40CAE3 equivalent, this device serves as a RoHS-compliant, MIL-PRF-19500 upscreenable TVS for industrial power supplies, telecom infrastructure interfaces, and automotive body control modules requiring robust surge immunity with <5 ns response time and 10/1000 µs waveform compliance.
Technical Context
The MDA3KP40CAE3 is a bidirectional TVS diode array built using silicon avalanche technology, delivering sub-nanosecond response to transient overvoltages. Its symmetrical structure enables equal clamping in both polarities, supporting AC-coupled signal lines and ungrounded bus protection.
It operates across –55 °C to +150 °C junction temperature, with full surge testing per specification and 3σ lot norm screening on standby current (ID). Moisture sensitivity is Level 1 (IPC/JEDEC J-STD-020B), eliminating dry-pack requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 40 V - Maximum continuous operating voltage before clamping initiates; matches 36 V nominal DC rails with safety margin. |
| V(BR) min/max | 44.4–49.1 V - Confirmed breakdown range at 1 mA; ensures reliable turn-on above system operating peaks. |
| VC @ IPP | ≤64.5 V at 46.4 A - Clamping voltage under 10/1000 µs surge; limits downstream IC stress below 65 V. |
| PPP | 3000 W - Peak pulse power handling capability; sustains IEC61000-4-5 Class 4 surges with 42 Ω source. |
| ID @ VWM | ≤2 µA - Ultra-low leakage at rated standoff; avoids loading of high-impedance sensor or reference circuits. |
| Response time | <5 ns - Bidirectional turn-on latency; mitigates ESD events faster than most interface ICs can react. |
| TJ/TSTG | –55 to +150 °C - Extended thermal range supports under-hood automotive and industrial enclosure deployments. |
Pinout & Package
MDA3KP40CAE3 uses a 3-pin surface-mount plastic package (void-free UL94V-0 epoxy) with cathode-defined polarity: Pin 1 and Pin 3 are cathodes, Pin 2 is the common anode. Marking includes date code and part number; polarity dot identifies Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel A) | Connects to protected line A; forms one half of bidirectional clamp path with Pin 2. |
| Pin 2 | Common Anode | Shared anode node; ties both TVS channels to ground or reference plane in differential protection. |
| Pin 3 | Cathode (Channel B) | Connects to protected line B; completes symmetrical clamp path with Pin 2 for AC or floating signals. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables protection of AC-coupled, differential, or ungrounded data lines without polarity constraints. |
| 3000 W peak pulse power (10/1000 µs) | Meets IEC61000-4-5 Class 4 with 42 Ω source impedance-critical for telecom and industrial port hardening. |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring wafer/lot traceability, burn-in, and extended environmental testing. |
| Level 1 moisture sensitivity | Eliminates baking prior to reflow; compatible with standard SMT assembly processes without dry-pack handling. |
| RoHS-compliant (e3) | Meets EU Directive 2011/65/EU; tin-only terminal plating ensures lead-free solder compatibility and long-term reliability. |
Applications
| Industrial Power Supply Inputs | Automotive Body Control Modules |
|---|---|
Use Scenario: 24 V DC input stage of programmable logic controllers exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary surge shunt element placed upstream of DC-DC converters and microcontrollers. Use Value: Clamps 46.4 A surges to ≤64.5 V, preventing damage to 75 V-rated input capacitors and enabling single-stage protection architecture. | Use Scenario: LIN bus or CAN FD physical layer interface in door module ECUs subject to battery disconnect transients. IC Role / Device Role / Timing Role: Bidirectional line protector between transceiver and harness connector. Use Value: Symmetrical clamping preserves signal integrity on bidirectional buses while surviving >3000 W pulses without degradation. |
| Telecom Base Station RF Front-End | Renewable Energy Inverter DC Link Monitoring |
Use Scenario: Protection of antenna tuner control lines against induced RF and nearby lightning coupling. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on analog control paths feeding GaN PA bias networks. Use Value: Sub-5 ns response prevents RF-induced latch-up in sensitive RFICs; 2 µA leakage avoids DC offset errors in tuning DACs. | Use Scenario: Voltage sense inputs monitoring 600 V DC link in solar inverters during grid fault recovery. IC Role / Device Role / Timing Role: Standoff-limited overvoltage clamp on isolated ADC front-end resistive dividers. Use Value: 40 V VWM aligns with 36 V auxiliary supply rails; 64.5 V VC ensures ADC input stays within ABS MAX rating during surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ40CA | 600 W PPP rating, same VWM and bidirectional configuration; smaller SMB package (vs. MDA's larger 3-pin molded case). | Limited to Class 2/3 IEC61000-4-5; insufficient for 3000 W Class 4 surge requirements. | Select when space-constrained layouts prioritize footprint over peak power handling. |
| SMCJ40CA | 1500 W PPP, same VWM and polarity; SMC package with higher thermal mass than SMB but lower than MDA. | Valid for Class 3 (42 Ω) but not Class 4; requires derating above 85 °C ambient. | Choose where cost and availability outweigh need for full 3000 W headroom and MIL-grade screening. |
Compared with SMBJ40CA and SMCJ40CA, the MDA3KP40CAE3 delivers double the peak pulse power of SMCJ40CA and five times that of SMBJ40CA-enabling single-device Class 4 compliance without parallel stacking, while supporting upscreening and extended temperature operation critical for aerospace and defense systems.

FAQ
What does the 'C' suffix in MDA3KP40CAE3 indicate?
The 'C' suffix in MDA3KP40CAE3 denotes bidirectional polarity-meaning the device provides symmetrical clamping for both positive and negative transients. This is essential for protecting AC-coupled interfaces like RS-485, CAN, or LIN buses where voltage polarity reverses. Unlike unidirectional variants (e.g., MDA3KP40AE3), MDA3KP40CAE3 has no inherent anode/cathode orientation relative to ground, enabling flexible placement across differential signal pairs.
Is MDA3KP40CAE3 compliant with IEC61000-4-5 Class 4 testing?
Yes, MDA3KP40CAE3 is rated for IEC61000-4-5 Class 4 with 42 Ω source impedance, delivering full 3000 W peak pulse power at 10/1000 µs. Its 46.4 A IPP and ≤64.5 V clamping voltage ensure compliance without external circuitry. The device also supports Class 3 with 12 Ω and Class 2 with 2 Ω source impedances, as confirmed in the RF01243 datasheet Figure 3 derating curves.
What is the meaning of 'e3' in MDA3KP40CAE3?
The 'e3' suffix in MDA3KP40CAE3 indicates RoHS-compliant terminal plating-specifically matte tin (Sn) only, with no lead or other restricted substances. This meets EU Directive 2011/65/EU and ensures compatibility with lead-free reflow profiles. The e3 marking appears on the device body and is documented in Microsemi's nomenclature guide on page 2 of RF01243 Rev B.
Can MDA3KP40CAE3 be used in place of MDA3KP40AE3?
No-MDA3KP40CAE3 and MDA3KP40AE3 are not interchangeable due to fundamental polarity differences. MDA3KP40AE3 is unidirectional (cathode-to-ground), while MDA3KP40CAE3 is bidirectional (symmetrical cathode-anode-cathode). Substituting one for the other risks improper clamping or open-circuit failure in DC-biased applications. Always verify signal topology: use MDA3KP40AE3 for grounded single-ended lines, MDA3KP40CAE3 for floating or AC-coupled paths.
What is the maximum junction temperature rating for MDA3KP40CAE3?
The maximum junction temperature (TJ) for MDA3KP40CAE3 is +150 °C, with a minimum of –55 °C. This rating is specified in the "Maximum Ratings" table on page 2 of RF01243 Rev B and applies across all operating conditions including surge events. Derating begins above 25 °C per Figure 3, maintaining ≥80% of 3000 W capability up to +100 °C ambient with proper PCB copper area.
