Product details
Overview
MDA3KP8.0A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability protection of voltage-sensitive circuits against ESD, EFT, lightning-induced surges, and inductive switching transients. It features 8.0 V standoff voltage (VWM), 8.89–9.83 V breakdown voltage (V(BR)), 13.6 V 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, key selection criteria include its 8 V working voltage compatibility with 5 V/8 V logic interfaces, 3000 W surge capability per 10/1000 µs waveform, RoHS-compliant matte-tin terminations, and MIL-PRF-19500 upscreening eligibility for aerospace and defense systems.
Technical Context
The MDA3KP8.0A employs silicon avalanche diode technology optimized for sub-100 ps response time and low clamping ratio (VC/V(BR) ≈ 1.45). Its unidirectional polarity and cathode-defined pin 1 enable precise placement in DC-biased signal/power lines where reverse conduction must be blocked during normal operation.
Rated for 3000 W peak pulse power under IEC 61000-4-5 (10/1000 µs, 42 Ω source), it delivers secondary lightning protection up to Class 4 and ESD immunity per IEC 61000-4-2 (±30 kV contact), with <50 µA standby current at 8 V and full derating above 25 °C per Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous DC or peak AC voltage the device blocks without clamping; matches 5 V–8 V logic supply rails. |
| V(BR) min/max | 8.89–9.83 V @ 1 mA - Confirmed avalanche onset range; ensures reliable triggering before downstream IC damage thresholds. |
| VC @ IPP | 13.6 V @ 220.6 A - Clamped voltage during worst-case 10/1000 µs surge; limits stress on protected 12 V systems. |
| PPP | 3000 W @ 10/1000 µs - Peak surge energy handling capacity; exceeds IEC 61000-4-5 Level 4 requirements. |
| ID @ VWM | 50 µA max - Low leakage at rated standoff; avoids unintended bias shift in high-impedance sensor inputs. |
| TJ/TSTG | –55 °C to +150 °C - Extended thermal range supports under-hood automotive, industrial motor drives, and avionics. |
Pinout & Package
Package: Void-free transfer-molded thermosetting epoxy case (UL94V-0), 5 g weight, RoHS-compliant matte-tin plating, pin 1 identified by dot marking. Dimensions: 21.03 × 6.86 × 8.64 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Anode-to-ground connection point; connects to protected line, cathode tied to system ground for unidirectional clamping. |
| Pin 2 | Anode | Reference node for clamping path; must connect directly to local ground plane with minimal inductance. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W surge rating | Enables single-device protection against IEC 61000-4-5 Class 4 lightning surges (42 Ω source) without cascaded TVS stages. |

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 8.0 V VWM and unidirectional polarity, DO-214AA package (smaller footprint, lower surge capacity) | Not suitable for IEC 61000-4-5 Class 4; limited to Class 2 lightning protection and lower-energy EFT events | Select when board space is constrained and surge threat level is ≤1 kV/42 Ω. |
| SMCJ8.0A | 1500 W PPP rating, identical VWM and V(BR) range, DO-214AB package (mid-size, higher thermal mass than SMBJ but half the power of MDA3KP8.0A) | Meets IEC 61000-4-5 Class 3 only; requires parallel devices for Class 4 compliance | Choose for cost-sensitive industrial controls where 3000 W headroom is unnecessary. |
Compared with SMBJ8.0A and SMCJ8.0A, the MDA3KP8.0A provides double the surge power handling of SMCJ8.0A and five times that of SMBJ8.0A within the same VWM class-enabling fewer components, simplified layout, and guaranteed Class 4 lightning immunity without derating or paralleling.

FAQ
What is the clamping voltage of the MDA3KP8.0A at its rated peak pulse current?
The MDA3KP8.0A 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 is measured per standard test methods defined in IEC 61000-4-5 and guarantees predictable voltage limiting during surge events, making the MDA3KP8.0A suitable for protecting 12 V systems where overvoltage beyond 14 V could cause functional interruption or damage.
Is the MDA3KP8.0A RoHS compliant and what does the 'e3' suffix indicate?
Yes, the MDA3KP8.0A is RoHS compliant, as confirmed by the 'e3' designation in its full part number marking. The 'e3' suffix indicates annealed matte-tin plating per JEDEC J-STD-020B, ensuring lead-free solderability and compliance with EU Directive 2011/65/EU. This makes the MDA3KP8.0A suitable for environmentally regulated production programs without requiring exemption waivers or special process controls.
Can the MDA3KP8.0A be used for bidirectional transient suppression?
No, the MDA3KP8.0A is a unidirectional TVS device, as indicated by the absence of the 'C' suffix in its part number. Bidirectional variants (e.g., MDA3KP8.0CA) are available separately and feature symmetrical clamping for AC-coupled or floating signal lines. Using the MDA3KP8.0A in bidirectional applications risks failure during reverse-polarity surges, so correct polarity alignment-cathode to protected line, anode to ground-is mandatory for proper operation of the MDA3KP8.0A.
What is the maximum operating temperature range for the MDA3KP8.0A?
The MDA3KP8.0A is rated for junction and storage temperatures from –55 °C to +150 °C, validated per Microsemi's reliability testing protocol. This extended range supports deployment in under-hood automotive electronics, industrial inverters, and avionics power supplies where ambient temperatures exceed 105 °C. Derating of peak pulse power begins above 25 °C, as shown in Figure 3 of the RF01243 datasheet, and must be applied for designs operating continuously above room temperature.
Does the MDA3KP8.0A require dry pack moisture protection prior to reflow soldering?
No, the MDA3KP8.0A has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it is not moisture-sensitive and does not require dry pack storage or floor-life management before reflow. Its void-free epoxy encapsulation and conformal terminal plating eliminate moisture ingress risk, allowing direct placement and standard Pb-free reflow profiles (peak 260 °C for 10 s) without preconditioning-reducing manufacturing overhead and eliminating bake-out steps for the MDA3KP8.0A.
