Product details
Overview
MDA3KP6.0A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 6.0 V standoff voltage (VWM), 6.67–7.37 V breakdown voltage (V(BR)), and 10.3 V maximum clamping voltage (VC) at 291.3 A peak pulse current, designed for secondary lightning protection per IEC61000-4-5 in telecom power interfaces.
For engineers reviewing the MDA3KP6.0A datasheet, MDA3KP6.0A pinout, MDA3KP6.0A application, or MDA3KP6.0A equivalent, key selection criteria include VWM matching system DC rail, VC margin relative to protected IC absolute maximum ratings, 10/1000 µs surge capability, MIL-PRF-19500 upscreening eligibility, and RoHS-compliant matte-tin terminations.
Technical Context
The MDA3KP6.0A operates as a silicon avalanche diode-based clamping device, triggered when reverse voltage exceeds its 6.67 V minimum breakdown threshold. It delivers sub-100 ps response time and sustains 3000 W peak pulse power under standardized 10/1000 µs waveform conditions.
Its unidirectional polarity defines odd-numbered pins as cathodes, and it is rated for -55 °C to +150 °C junction temperature with 1000 µA standby current at 6.0 V. Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1-no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before conduction begins |
| V(BR) min/max | 6.67–7.37 V @ 10 mA - ensures reliable turn-on above system nominal rail while avoiding false triggering |
| VC @ IPP | 10.3 V @ 291.3 A - clamping voltage during full-rated 10/1000 µs surge, defining worst-case stress on downstream circuitry |
| PPP | 3000 W @ 10/1000 µs - peak surge handling capacity validated per IEC61000-4-5 with 42 Ω source impedance |
| ID @ VWM | 1000 µA - leakage current at rated standoff, low enough to avoid loading 5–12 V power rails |
| TJ/TSTG | -55 to +150 °C - enables deployment in industrial and aerospace environments with wide thermal excursions |
Pinout & Package
MDA3KP6.0A uses a 3-pin surface-mount package with void-free UL94V-0 epoxy body and matte-tin terminations. Pin 1 is marked by a dot on top of the package; odd-numbered pins are cathodes per unidirectional construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., DC input); conducts surge current to ground reference when clamped |
| Pin 2 | Anode | Common ground connection for all TVS elements in the array; must be low-inductance path to system earth |
| Pin 3 | Cathode | Second protected line (e.g., return or auxiliary rail); shares anode (Pin 2) for bidirectional suppression configuration |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse rating | Validated clamping performance under IEC61000-4-5 Class 1–4 secondary lightning test conditions with 42 Ω source |
| Sub-100 ps response time | Enables protection against ESD (IEC61000-4-2) and EFT (IEC61000-4-4) without signal distortion or timing skew |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring wafer lot traceability, 3σ ID screening, and conformance inspection |
| RoHS-compliant e3 marking | Matte-tin plating meets JEDEC J-STD-020B Level 1 moisture sensitivity-no bake-out required prior to reflow |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A | 600 W PPP rating, same VWM and V(BR) range, DO-214AA package | Limited to Class 1–2 IEC61000-4-5; insufficient for 3000 W telecom lightning events | Select when board space is constrained and surge energy is ≤600 W |
| SMCJ6.0A | 1500 W PPP, same VWM/V(BR), larger DO-214AB package | Meets Class 1–3 IEC61000-4-5 but not Class 4; lower clamping margin than MDA3KP6.0A | Choose for cost-sensitive industrial designs where 1500 W surge headroom suffices |
Compared with SMBJ6.0A and SMCJ6.0A, the MDA3KP6.0A provides double the surge energy handling of SMCJ6.0A and five times that of SMBJ6.0A-enabling single-device compliance with IEC61000-4-5 Class 4 at 42 Ω, critical for telecom infrastructure and aerospace power entry designs.

FAQ
What is the clamping voltage of the MDA3KP6.0A at its rated peak pulse current?
The MDA3KP6.0A has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPP) of 291.3 A under 10/1000 µs waveform conditions. This value is measured across the device terminals during full-power surge testing and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Is the MDA3KP6.0A RoHS compliant and what does the 'e3' marking indicate?
Yes, the MDA3KP6.0A is RoHS compliant, indicated by the 'e3' suffix in its marking per Microsemi's nomenclature. The 'e3' designation confirms matte-tin plating per JEDEC standards and compliance with Directive 2011/65/EU, including lead content below 1000 ppm and absence of restricted substances such as cadmium, mercury, hexavalent chromium, PBB, and PBDE.
Can the MDA3KP6.0A be used for bidirectional transient suppression?
No-the MDA3KP6.0A is unidirectional, as confirmed by its part number lacking the 'C' suffix and its polarity definition stating "odd number pins are cathodes." For bidirectional operation, the MDA3KP6.0CA variant must be selected; it features symmetrical breakdown in both directions and is explicitly listed in the datasheet for Class 4 lightning protection with 2 Ω source impedance.
What is the maximum operating temperature range for the MDA3KP6.0A?
The MDA3KP6.0A is rated for junction and storage temperatures from -55 °C to +150 °C. This range supports deployment in extended industrial, automotive under-hood, and aerospace environments. Derating of peak pulse power begins above 25 °C per Figure 3 in the RF01243 datasheet, with 50% power capability retained at +125 °C.
Does the MDA3KP6.0A require moisture sensitivity handling prior to solder reflow?
No-the MDA3KP6.0A has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it may be stored indefinitely at ambient conditions and placed directly into reflow without baking or dry packing. This eliminates process steps and reduces risk of popcorn cracking during assembly.
