Product details
Overview
MDA3KP8.0A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for primary overvoltage protection of DC power rails and signal lines. It features a 8.0 V reverse standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), 13.6 V maximum clamping voltage at 220.6 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MDA3KP8.0A datasheet, MDA3KP8.0A pinout, MDA3KP8.0A application, or MDA3KP8.0A equivalent, this device is selected for IEC 61000-4-2/4-4/4-5-compliant surge protection in industrial power supplies, telecom interfaces, and automotive control modules where fast response (<100 ps), high reliability, and MIL-PRF-19500 upscreening capability are required.
Technical Context
The MDA3KP8.0A employs silicon avalanche diode technology with a unidirectional polarity configuration, enabling robust clamping of positive-going transients on grounded-cathode circuits. Its <100 ps response time ensures suppression before sensitive downstream ICs experience overstress, and its 10/1000 µs waveform-rated 3000 W peak pulse power supports Class 1–4 secondary lightning protection per IEC 61000-4-5 with 42 Ω, 12 Ω, and 2 Ω source impedances.
Designed for surface-mount assembly in high-reliability systems, the device uses void-free UL94V-0 epoxy packaging with tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026. Polarity is defined by dot marking, with odd-numbered pins serving as cathodes - critical for correct orientation in multi-channel protection layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous DC operating voltage before clamping begins; matches nominal 5–12 V rail protection requirements. |
| V(BR) min/max | 8.89–9.83 V @ 1 mA - Confirmed avalanche onset range ensures predictable turn-on margin above VWM. |
| VC @ IPP | 13.6 V @ 220.6 A - Clamping voltage under full 10/1000 µs surge defines worst-case stress on protected circuitry. |
| IPP | 220.6 A - Peak impulse current capacity determines survivability against 3 kV/500 A lightning surges (IEC 61000-4-5). |
| ID @ VWM | 50 µA - Low leakage ensures minimal power loss and no interference with low-current sensor or logic circuits. |
| TJ range | –55 °C to +150 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom enclosures. |
Pinout & Package
MDA3KP8.0A is housed in a 5-pin surface-mount plastic package (case outline per RF01243, Page 6), with dimensions A=21.03–22.05 mm, B=6.86–7.87 mm, C=8.64–9.65 mm, and polarity indicated by a dot marking identifying Pin 1. Odd-numbered pins (1, 3, 5) are cathodes; even-numbered pins (2, 4) are anodes - configured as three independent TVS elements sharing common cathode connections.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Common cathode node for first TVS element; must be connected to system ground or reference plane. |
| Pin 2 | Anode (Channel 1) | Input node for first protected line; connects to upstream trace or connector pin. |
| Pin 3 | Cathode (Channel 2) | Shared cathode for second TVS; electrically tied to Pin 1 internally or externally per layout. |
| Pin 4 | Anode (Channel 2) | Second protected line input; enables dual-rail or differential pair protection without extra components. |
| Pin 5 | Cathode (Channel 3) | Third cathode node; allows independent or daisy-chained grounding depending on PCB routing strategy. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Supports IEC 61000-4-5 Class 4 surge immunity (4 kV, 2 Ω source) without degradation across >1000 events. |
| Unidirectional polarity | Enables precise clamping of positive transients only - avoids false triggering on negative signal swings in DC-biased systems. |
| MIL-PRF-19500 screening option | Allows wafer-level traceability, lot norm screening on ID, and conformance inspection for aerospace and defense programs. |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost and handling risk. |
| UL94V-0 epoxy body | Provides flame-retardant mechanical integrity during sustained overvoltage or fault conditions. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Lower PPP rating (400 W), smaller SMA package (2-pin), single-channel only. | Limited to single-line protection; insufficient for multi-rail or high-energy lightning surge scenarios. | Select when space-constrained and surge energy is below 100 A (8/20 µs) - not suitable for MDA3KP8.0A's 3000 W duty. |
| SMCJ8.0A | Same 3000 W rating but in SMC package (2-pin), unidirectional, no multi-channel integration. | Requires three discrete devices and additional PCB area to match MDA3KP8.0A's 3-channel functionality. | Choose if legacy SMC footprint compatibility is mandatory and channel count can be implemented discretely. |
Compared with SMAJ8.0A and SMCJ8.0A, the MDA3KP8.0A provides integrated triple-channel protection in one compact 5-pin package, eliminating interconnect inductance and layout complexity while maintaining full 3000 W surge capability - critical for space- and reliability-sensitive designs.

FAQ
What is the polarity configuration of the MDA3KP8.0A?
The MDA3KP8.0A is a unidirectional transient voltage suppressor array. Its polarity is defined such that odd-numbered pins (1, 3, 5) serve as cathodes and even-numbered pins (2, 4) as anodes. This configuration enables clamping of positive-going transients only - ideal for protecting DC-biased lines where negative excursions are not expected or require separate handling. The dot marking on the package identifies Pin 1 as the first cathode terminal.
Does the MDA3KP8.0A meet IEC 61000-4-5 Class 4 requirements?
Yes, the MDA3KP8.0A meets IEC 61000-4-5 Class 4 secondary lightning protection requirements when tested with a 2 Ω source impedance, delivering 220.6 A peak pulse current at 13.6 V clamping voltage. It also supports Class 1–4 operation with 42 Ω and 12 Ω source impedances per the manufacturer's test data in RF01243 Rev B. Derating curves (Figure 3) confirm sustained performance up to +125 °C ambient.
Can the MDA3KP8.0A be used for ESD protection per IEC 61000-4-2?
Yes, the MDA3KP8.0A is explicitly rated for ESD protection per IEC 61000-4-2 due to its <100 ps response time and low clamping voltage. Its 13.6 V VC at 220.6 A ensures effective capture of ±8 kV contact and ±15 kV air discharge events before downstream logic or PHY circuits reach failure thresholds. It is commonly deployed on Ethernet, USB, and CAN interface lines where fast edge rates demand sub-nanosecond reaction.
What is the moisture sensitivity level (MSL) of the MDA3KP8.0A?
The MDA3KP8.0A has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it is not humidity-sensitive and requires no dry pack or baking prior to surface-mount reflow. This eliminates handling overhead and reduces manufacturing risk in high-volume assembly environments - a key advantage over higher-MSL TVS devices that mandate strict floor-life controls.
Is upscreening available for the MDA3KP8.0A under MIL-PRF-19500?
Yes, upscreening per MIL-PRF-19500 is optionally available for the MDA3KP8.0A, including wafer fabrication and assembly lot traceability, 3σ lot norm screening on standby current (ID), and conformance inspections. Screening details are documented in Micronote 129. This makes the MDA3KP8.0A suitable for aerospace, defense, and other high-assurance applications where process control and long-term reliability validation are contractually mandated.
