Product details
Overview
MDA3KP8.0AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 8.0 V standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), and 13.6 V maximum clamping voltage (VC) at 220.6 A peak pulse current (IPP). It delivers sub-100 ps response time and operates across –55 °C to +150 °C for secondary lightning protection per IEC61000-4-5 in telecom power interfaces.
For engineers reviewing the MDA3KP8.0AE3 datasheet, MDA3KP8.0AE3 pinout, MDA3KP8.0AE3 application, or MDA3KP8.0AE3 equivalent, key selection criteria include VWM matching system DC rail, VC margin relative to protected IC absolute maximum ratings, IPP derating above 25 °C, and RoHS-compliant matte-tin termination compatibility with lead-free reflow profiles.
Technical Context
The MDA3KP8.0AE3 is a single-channel unidirectional TVS diode designed for parallel-connected overvoltage clamping on DC power lines. Its silicon avalanche structure enables <100 ps response to transients, with clamping action triggered when reverse voltage exceeds V(BR) min of 8.89 V under 1 mA test current.
It meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and IEC61000-4-5 (lightning surge) immunity requirements using 10/1000 µs waveform testing. Standby leakage ID is ≤50 µA at 8.0 V, and thermal derating begins above 25 °C per Figure 3, maintaining 3000 W peak pulse power only at ambient ≤25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous DC operating voltage before clamping initiates |
| V(BR) min/max | 8.89–9.83 V @ 1 mA - Ensures reliable turn-on above nominal rail while avoiding false triggering |
| VC @ IPP | 13.6 V @ 220.6 A - Clamped voltage seen by downstream circuit during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - Peak transient energy absorption capability under standard surge waveform |
| ID @ VWM | ≤50 µA - Low leakage preserves efficiency in always-on power rails |
| TJ/TSTG | –55 °C to +150 °C - Supports operation in automotive engine bays and industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | 600 W PPP rating, same VWM and VC, DO-214AA package | Lower surge capacity limits use to Class 2/3 IEC61000-4-5 or non-lightning environments | Select when board space is constrained and surge threat level is moderate (e.g., indoor industrial) |
| 1.5KE8.0A | Through-hole TO-218 package, 1500 W PPP, higher thermal mass but larger footprint | Preferred for legacy designs or high-temperature chassis mounting where airflow cools bulkier package | Choose when rework tolerance and manual assembly are prioritized over SMT density |
Compared with SMBJ8.0A and 1.5KE8.0A, the MDA3KP8.0AE3 provides 2× and 2× higher peak pulse power respectively in an SMT package, enabling compact, high-reliability protection for Class 4 lightning environments without compromising thermal performance or RoHS compliance.

FAQ
What is the clamping voltage of the MDA3KP8.0AE3 at its rated peak pulse current?
The MDA3KP8.0AE3 has a maximum clamping voltage (VC) of 13.6 V at its rated peak pulse current (IPP) of 220.6 A under 10/1000 µs waveform conditions. This value ensures protected circuits remain below critical voltage thresholds during worst-case surge events, and it is measured with the device mounted on standard PCB land patterns per JEDEC guidelines.
Is the MDA3KP8.0AE3 RoHS compliant and lead-free solder compatible?
Yes, the MDA3KP8.0AE3 is RoHS compliant (as indicated by the "e3" suffix) and features annealed matte-tin plating that supports lead-free reflow soldering up to 260 °C for 10 seconds. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, eliminating dry-pack requirements and enabling unlimited floor life in controlled environments.
How does the MDA3KP8.0AE3 compare to bidirectional TVS devices like MDA3KP8.0CE3?
The MDA3KP8.0AE3 is unidirectional and intended for DC power line protection where polarity is fixed, while MDA3KP8.0CE3 is bidirectional for AC or dual-polarity signal lines. The unidirectional version offers lower forward voltage drop and tighter V(BR) tolerance (±5%), making MDA3KP8.0AE3 preferable for 8 V DC rails with strict clamping margins.
What is the standoff voltage rating and why is it important for selecting the MDA3KP8.0AE3?
The MDA3KP8.0AE3 has a rated working standoff voltage (VWM) of 8.0 V, meaning it remains non-conductive up to this DC or peak AC voltage. Selecting a VWM ≥ system operating voltage prevents false triggering while ensuring sufficient margin below V(BR) min (8.89 V) to accommodate tolerances and temperature drift-critical for stable operation in 8 V nominal systems.
Does the MDA3KP8.0AE3 require derating at elevated ambient temperatures?
Yes, the MDA3KP8.0AE3 requires thermal derating above 25 °C ambient, as shown in Figure 3 of the datasheet. At 85 °C, its peak pulse power drops to approximately 70% of the 3000 W rating. Designers must verify clamping performance under worst-case operating temperature and adjust layout for adequate copper area or airflow to maintain reliability in high-temp environments.
