Product details
Overview
MDA3KP16AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 16 V standoff voltage (VWM), 17.8–19.7 V breakdown range (V(BR)), and 26.0 V maximum clamping voltage (VC) at 115.4 A peak pulse current (IPP). It delivers sub-100 ps response for ESD/EFT protection per IEC61000-4-2/4-4 and secondary lightning protection per IEC61000-4-5 in industrial power interfaces.
For engineers reviewing the MDA3KP16AE3 datasheet, MDA3KP16AE3 pinout, MDA3KP16AE3 application, or MDA3KP16AE3 equivalent, key selection criteria include its 16 V working voltage, 26.0 V clamping performance at 115.4 A, RoHS-compliant e3 marking, MIL-PRF-19500 upscreening capability, and 5 g thermoset epoxy package with defined Pin 1 dot marking.
Technical Context
The MDA3KP16AE3 operates as a unidirectional avalanche diode array optimized for high-energy transient suppression in DC power rails and signal lines. Its 10/1000 µs waveform rating of 3000 W and <100 ps response time enable protection against fast-rising ESD events and slower inductive switching surges.
It features a 16 V rated standoff voltage (VWM), minimum 17.8 V breakdown at 1 mA, and clamps to ≤26.0 V at 115.4 A IPP - ensuring downstream ICs remain below absolute maximum ratings during surge events. Standby leakage is limited to 2 µA at VWM, supporting low-power system integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 17.8–19.7 V @ 1 mA - defines reliable avalanche initiation threshold for predictable clamping onset |
| VC @ IPP | 26.0 V @ 115.4 A - clamping voltage under full 3000 W 10/1000 µs surge, limiting stress on protected circuitry |
| ID @ VWM | ≤2 µA - ultra-low leakage preserves battery life and avoids false triggering in high-impedance nodes |
| PPP | 3000 W @ 10/1000 µs - peak power handling capacity validated per Figure 1, enabling robust Class 3/4 lightning protection |
| TJ/TSTG | −55 °C to +150 °C - wide operating and storage range supports automotive under-hood and industrial control environments |
| Moisture Sensitivity | Level 1 per J-STD-020B - no dry pack required, simplifying SMT assembly and reducing BOM handling overhead |
Pinout & Package
MDA3KP16AE3 uses a 3-pin surface-mount plastic package (case outline per Page 6 of RF01243 Rev B) with void-free UL94V-0 thermoset epoxy body, tin-lead or matte-tin plating, and polarity defined by a dot marking Pin 1. Odd-numbered pins are cathodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of first TVS element | Primary surge current return path; must connect to protected line's reference (e.g., ground or rail) |
| Pin 2 | Anode common node | Shared anode for all internal TVS elements; connects to system ground or negative rail |
| Pin 3 | Cathode of second TVS element | Second protected line connection; enables dual-line or differential protection topology |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Validated 10/1000 µs surge handling enables compliance with IEC61000-4-5 Class 3 (42 Ω source) and Class 2 (2 Ω source) |
| Unidirectional construction | Prevents reverse-bias leakage in DC-coupled applications while maintaining fast clamping on positive transients |
| MIL-PRF-19500 screening option | Supports high-reliability programs requiring wafer lot traceability, 3σ ID screening, and conformance inspection |
| RoHS-compliant e3 marking | Meets EU Directive 2011/65/EU with lead-free terminations and compliant materials, verified per JESD22-A112 |
| Sub-100 ps response time | Ensures clamping activation before ESD pulses (IEC61000-4-2) damage sensitive CMOS inputs or communication transceivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | 600 W PPP rating, same VWM and VC, but lower IPP (33.3 A) and smaller SMB package | Not suitable for 3000 W lightning-level surges; limited to board-level ESD and low-energy switching noise | Select MDA3KP16AE3 when IEC61000-4-5 Class 3/4 compliance or >100 A surge handling is required |
| SMCJ16A | 1500 W PPP, same VWM/VC, SMC package, 87.8 A IPP - half the energy handling of MDA3KP16AE3 | Adequate for Class 2 lightning (2 Ω source) but fails Class 3 (42 Ω source) per IEC61000-4-5 test profiles | Choose MDA3KP16AE3 where full 3000 W rating is mandated by safety standards or system-level surge testing |
Compared with SMBJ16A and SMCJ16A, the MDA3KP16AE3 provides double the peak pulse power and 31% higher IPP than SMCJ16A, enabling single-device compliance with stringent secondary lightning requirements without parallel stacking or derating.

FAQ
What is the clamping voltage of the MDA3KP16AE3 at its rated peak pulse current?
The MDA3KP16AE3 has a maximum clamping voltage (VC) of 26.0 V at its rated peak pulse current (IPP) of 115.4 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the RF01243 datasheet and ensures protected circuits remain within safe operating limits during high-energy transients. The MDA3KP16AE3 achieves this clamping performance while maintaining low standby leakage of ≤2 µA at 16 V.
Is the MDA3KP16AE3 RoHS-compliant, and what does the 'e3' suffix indicate?
Yes, the MDA3KP16AE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide (Page 2, RF01243 Rev B). The 'e3' designation specifies lead-free terminations and compliance with EU Directive 2011/65/EU. The MDA3KP16AE3 uses annealed matte-tin plating and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity, eliminating dry pack requirements for SMT processing.
Can the MDA3KP16AE3 be used for bidirectional transient protection?
No, the MDA3KP16AE3 is unidirectional only, as indicated by the absence of a 'C' suffix (which denotes bidirectional variants like MDA3KP16CE3). Its electrical characteristics - including forward clamping voltage (VFS = 4.0 V) and polarity marking (odd pins = cathodes) - are specified for single-polarity surge suppression. For bidirectional applications, select the MDA3KP16CE3 variant, which provides symmetrical clamping for AC-coupled or floating signal lines.
What is the thermal derating behavior of the MDA3KP16AE3 above 25°C ambient?
The MDA3KP16AE3 follows a linear derating curve shown in Figure 3 of RF01243 Rev B: peak pulse power decreases from 100% at 25°C to approximately 50% at 100°C junction temperature. This means at 100°C TJ, its effective PPP drops to ~1500 W. Designers must ensure adequate PCB copper area and airflow to maintain TJ ≤100°C during repetitive surge events. The MDA3KP16AE3's −55°C to +150°C junction range supports operation in harsh thermal environments.
How does the MDA3KP16AE3 compare to standard SMA/SMB/SMC package TVS diodes in surge handling?
The MDA3KP16AE3 delivers 3000 W peak pulse power - five times that of SMBJ16A (600 W) and double that of SMCJ16A (1500 W) - due to its larger thermoset epoxy package and optimized die structure. Its 115.4 A IPP and 26.0 V VC enable single-device compliance with IEC61000-4-5 Class 3 (42 Ω source), whereas SMB/SMC variants require parallel staging. The MDA3KP16AE3 also offers MIL-PRF-19500 upscreening options unavailable in standard packages.
