Product details
Overview
MXDA3KP36A 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 rails and signal lines. It features a 36 V standoff voltage (VWM), 40.0–44.2 V breakdown range (V(BR)), 58.1 V clamping voltage at 51.6 A peak pulse current, and operates from −55 °C to +150 °C.
For engineers reviewing the MXDA3KP36A datasheet, MXDA3KP36A pinout, MXDA3KP36A application, or MXDA3KP36A equivalent, key selection criteria include clamping performance under IEC61000-4-5 (42 Ω source), thermal derating above 25 °C, standoff voltage margin relative to system peak operating voltage, and RoHS-compliant matte-tin termination compatibility with lead-free reflow.
Technical Context
The MXDA3KP36A is a single-channel, unidirectional TVS diode optimized for fast transient suppression in industrial and telecom power interfaces. Its sub-100 ps response time enables effective protection against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and induced surges up to 3000 W at 10/1000 µs waveform.
It uses silicon avalanche technology with controlled breakdown characteristics and is rated for surge testing per MIL-PRF-19500 screening options. The device exhibits 2 µA maximum standby current at 36 V and requires no dry pack per IPC/JEDEC J-STD-020B Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 40.0–44.2 V @ 1 mA - Ensures reliable avalanche initiation above system operating voltage margin |
| VC @ IPP | 58.1 V @ 51.6 A - Clamped voltage seen by protected circuit during worst-case 10/1000 µs surge |
| PPP | 3000 W @ 10/1000 µs - Peak power dissipation capability defines surge energy handling limit |
| ID @ VWM | ≤2 µA - Low leakage preserves efficiency in high-impedance bias or sensing circuits |
| TJ/TSTG | −55 to +150 °C - Enables deployment in extended-temperature industrial and automotive under-hood environments |
| Moisture Level | IPC/JEDEC J-STD-020B Level 1 - No baking required before SMT assembly |
Pinout & Package
MXDA3KP36A is housed in a void-free thermosetting epoxy package (UL94V-0) with matte-tin-plated terminals. Pin 1 is marked by a dot on the top surface and serves as the cathode terminal; the anode connects to the common tab (pin 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts when transient exceeds V(BR), shunting current to ground |
| Pin 2 | Anode / Common Tab | Typically tied to system ground or low-impedance return path; forms the current sink during clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | 600 W PPP rating, SMA package, 58.1 V VC @ 10.3 A IPP | Limited to lower-energy surges; unsuitable for IEC61000-4-5 Class 4 | Select SMAJ36A only for cost-sensitive consumer designs where 3000 W surge immunity is not required. |
| SMCJ36A | 1500 W PPP rating, SMC package, 58.1 V VC @ 25.8 A IPP | Half the energy handling of MXDA3KP36A; marginal for 42 Ω IEC61000-4-5 Class 3 | Use SMCJ36A where board space allows larger SMC footprint but 3000 W is not mandated by system spec. |
Compared with SMAJ36A and SMCJ36A, the MXDA3KP36A delivers double the surge energy capacity of SMCJ36A and five times that of SMAJ36A-enabling single-device compliance with demanding industrial and telecom surge standards without parallel staging.

FAQ
What is the clamping voltage of MXDA3KP36A at its rated peak pulse current?
The MXDA3KP36A has a maximum clamping voltage (VC) of 58.1 V at its rated peak pulse current (IPP) of 51.6 A under 10/1000 µs waveform conditions. This value is measured per Figure 2 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The MXDA3KP36A maintains this clamping performance across its full operating temperature range.
Is MXDA3KP36A RoHS compliant and what does the 'e3' marking indicate?
Yes, MXDA3KP36A is RoHS compliant, as confirmed by the 'e3' suffix in its full part number per Microsemi's nomenclature guide. The 'e3' designation specifies annealed matte-tin plating per JEDEC standards and full compliance with Directive 2011/65/EU. This ensures compatibility with lead-free reflow processes and eliminates hexavalent chromium and cadmium in the termination finish.
Does MXDA3KP36A require moisture sensitivity level (MSL) baking before reflow soldering?
No, MXDA3KP36A does not require pre-reflow baking because it is rated at IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1. This means the device may be stored indefinitely at ≤30 °C/60% RH and placed directly into reflow without dry-pack or floor-life restrictions-reducing manufacturing overhead and eliminating popcorning risk.
How does the standoff voltage (VWM) of MXDA3KP36A relate to system operating voltage?
The 36 V VWM of MXDA3KP36A must be selected to equal or exceed the maximum continuous peak operating voltage of the protected line. For example, in a 24 V nominal DC system with ±10% tolerance and ripple, peak voltage reaches ~26.4 V-well below 36 V, ensuring no leakage or premature conduction. Exceeding VWM risks excessive ID and thermal runaway.
Can MXDA3KP36A be used for bidirectional transient protection?
No, MXDA3KP36A is unidirectional only, as indicated by the absence of 'C' in its part number. Bidirectional variants (e.g., MXDA3KP36CA) are available separately. Using MXDA3KP36A on AC-coupled or bipolar signal lines would result in forward conduction during negative half-cycles, causing malfunction or damage. Always match polarity to system topology.
