Product details
Overview
MDA3KP9.0A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in power supply inputs, telecom interfaces, and industrial control I/O. It features a 9.0 V reverse standoff voltage (VWM), 10.0–11.1 V breakdown voltage (V(BR)), 15.4 V maximum clamping voltage at 194.8 A peak pulse current, and operates from −55 °C to +150 °C.
For engineers reviewing the MDA3KP9.0A datasheet, MDA3KP9.0A pinout, MDA3KP9.0A application, or MDA3KP9.0A equivalent, this page delivers verified electrical parameters, MIL-PRF-19500 upscreening options, IEC61000-4-2/4-4/4-5 compliance context, package dimensions, and real-world protection use cases - all specific to the MDA3KP9.0A variant.
Technical Context
The MDA3KP9.0A is a single-channel, unidirectional TVS diode optimized for fast clamping of high-energy transients with <100 ps response time. Its 3000 W peak pulse power rating is defined at 10/1000 µs waveform, and it meets IEC61000-4-5 Class 4 secondary lightning protection when tested with 2 Ω source impedance.
It exhibits 10 µA maximum standby current at 9.0 V VWM, 15.4 V clamping voltage at 194.8 A IPP, and is rated for solder reflow up to 260 °C. Polarity is defined by dot marking; odd-numbered pins are cathodes, confirming its discrete diode topology within a multi-pin plastic package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous DC or peak AC operating voltage before clamping begins |
| V(BR) min/max | 10.0–11.1 V @ 1 mA - Ensures reliable turn-on above system nominal voltage with margin |
| VC @ IPP | 15.4 V @ 194.8 A - Clamped voltage seen by protected circuit during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges without failure in industrial power rails |
| ID @ VWM | ≤10 µA - Negligible leakage at rated standoff, critical for low-power sensor interfaces |
| TJ range | −55 °C to +150 °C - Supports operation in under-hood automotive, base station, and motor drive environments |
| Response time | <100 ps - Fast enough to suppress ESD events before downstream IC damage occurs |
Pinout & Package
MDA3KP9.0A uses a 3-pin TO-277A (SMB) surface-mount package with void-free UL94V-0 epoxy body, tin-lead or matte-tin plating, and polarity indicated by a dot marking pin 1. Odd-numbered pins are cathodes per device polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; clamps positive transients to ground when used anode-to-ground |
| Pin 2 | Anode | Typically tied to system ground; completes conduction path during overvoltage event |
| Pin 3 | Cathode | Redundant cathode terminal - electrically common with Pin 1; improves current sharing and thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables robust protection against IEC61000-4-5 Class 4 surges (2 Ω source) without derating at 25 °C |
| MIL-PRF-19500 upscreening option | Supports high-reliability aerospace and defense programs requiring lot traceability and 3σ ID screening |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost and risk |
| Unidirectional construction | Provides asymmetric clamping ideal for DC-biased lines like power supplies and RS-485 VCC rails |
| RoHS-compliant (e3) | Meets global environmental compliance requirements without performance trade-offs in surge handling |
Applications
| Industrial PLC I/O Protection | Telecom Power Input |
|---|---|
Use Scenario: 24 V DC input stage of programmable logic controller exposed to inductive switching noise and field wiring surges. IC Role / Device Role / Timing Role: TVS diode clamping transient energy before it reaches upstream DC-DC converter and microcontroller. Use Value: Limits voltage to ≤15.4 V during 194.8 A surge, preventing latch-up or gate oxide damage in 3.3 V/5 V logic. | Use Scenario: −48 V telecom power feed entering remote radio unit enclosure with long cable runs. IC Role / Device Role / Timing Role: Primary surge suppression element on power rail, coordinated with upstream MOV and downstream filter caps. Use Value: Absorbs 3000 W pulses per IEC61000-4-5 (2 Ω source), maintaining rail integrity during lightning-induced coupling. |
| Automotive Body Control Module | Medical Equipment Power Entry |
Use Scenario: 12 V battery-supplied body control module subjected to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Fast-response TVS placed directly at connector entry point to shunt surge energy to chassis ground. Use Value: Sub-100 ps response ensures clamping before 12 V rail exceeds 16 V threshold of downstream LDOs and CAN transceivers. | Use Scenario: AC/DC adapter input stage in Class II medical device requiring reinforced isolation and low leakage. IC Role / Device Role / Timing Role: Secondary protection after primary MOV, guarding against fast-rising EFT bursts per IEC61000-4-4. Use Value: 10 µA max ID at 9 V ensures no impact on isolation resistance or leakage current safety limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | 600 W PPP rating, same VWM and VC, but lower IPP (91.6 A) and no MIL-PRF-19500 screening option | Suitable for commercial-grade consumer electronics; insufficient for Class 4 IEC61000-4-5 with 2 Ω source | Select MDA3KP9.0A when 3000 W surge immunity and high-reliability screening are required. |
| SMCJ9.0A | 1500 W PPP, same VWM, higher VC (16.7 V), and no upscreening path per MIL-PRF-19500 | Acceptable for industrial controls with moderate surge exposure; lacks Class 4 validation at 2 Ω | Choose MDA3KP9.0A where full 3000 W capability and aerospace-grade traceability are mandatory. |
Compared with SMAJ9.0A and SMCJ9.0A, the MDA3KP9.0A delivers double the pulse power handling of SMCJ9.0A and over five times that of SMAJ9.0A while supporting military-grade reliability screening - making it uniquely suited for mission-critical infrastructure where surge margin and component pedigree are non-negotiable.

FAQ
What is the clamping voltage of the MDA3KP9.0A at its rated peak pulse current?
The MDA3KP9.0A has a maximum clamping voltage (VC) of 15.4 V at its rated peak pulse current (IPP) of 194.8 A under 10/1000 µs waveform conditions. This value is guaranteed across temperature and represents the highest voltage the protected circuit will experience during a full-rated surge event. The MDA3KP9.0A maintains this clamping performance while delivering 3000 W peak pulse power - a key differentiator versus lower-power alternatives.
Is the MDA3KP9.0A RoHS compliant?
Yes, the MDA3KP9.0A is RoHS compliant, indicated by the "e3" suffix in its full part marking per Microsemi's nomenclature guide. It uses annealed matte-tin or tin-lead plating compatible with standard reflow profiles and meets JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating dry-pack requirements. The MDA3KP9.0A's RoHS compliance does not compromise its 3000 W surge rating or MIL-PRF-19500 upscreening capability.
Can the MDA3KP9.0A be used for bidirectional transient protection?
No, the MDA3KP9.0A is unidirectional only, as confirmed by its part number suffix "A" (vs. "C" for bidirectional variants like MDA3KP9.0C). Its electrical behavior clamps only positive-going transients relative to ground when anode is grounded. For AC or bipolar signal lines requiring symmetrical clamping, a bidirectional variant must be selected - the MDA3KP9.0A is not suitable for such use cases.
What is the maximum operating temperature range for the MDA3KP9.0A?
The MDA3KP9.0A is rated for junction and storage temperatures from −55 °C to +150 °C, validated per manufacturer specifications. This wide range supports deployment in under-hood automotive ECUs, outdoor telecom base stations, and industrial motor drives where ambient temperatures exceed 105 °C. Derating of peak pulse power begins above 25 °C, per Figure 3 in the official datasheet for MDA3KP9.0A.
Does the MDA3KP9.0A require special PCB layout considerations?
Yes - the MDA3KP9.0A requires low-inductance layout to preserve its <100 ps response time. Short, wide traces between pins 1/3 (cathodes) and the protected line, plus direct connection of pin 2 (anode) to a low-impedance ground plane, are essential. The MDA3KP9.0A's TO-277A package also mandates adherence to the pad layout specified in the datasheet (Page 7) to ensure solder joint reliability and thermal performance during repeated surge events.
