Product details
Overview
MXLDA3KP9.0A from Microsemi (now Microchip) is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability overvoltage protection in power rails and signal lines. 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 - used in industrial motor drives, telecom power supplies, and railway signaling interfaces.
For engineers reviewing the MXLDA3KP9.0A datasheet, MXLDA3KP9.0A pinout, MXLDA3KP9.0A application, or MXLDA3KP9.0A equivalent, key selection criteria include clamping performance under 10/1000 µs surge, standoff voltage margin relative to DC rail, thermal derating above 25 °C, and MIL-PRF-19500 upscreening eligibility for aerospace-grade deployments.
Technical Context
The MXLDA3KP9.0A is a single-channel, unidirectional TVS diode optimized for fast transient suppression with <100 ps response time and 3000 W peak pulse power handling per IEC 61000-4-5 (42 Ω source). Its silicon avalanche structure enables precise breakdown at 10.0–11.1 V and clamps to ≤15.4 V at 194.8 A, limiting downstream voltage stress during ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and secondary lightning events.
It is rated for continuous operation from −55 °C to +150 °C, with junction temperature derating beginning at 25 °C per Figure 3. The device uses void-free UL94V-0 epoxy packaging, tin-lead or matte-tin terminations, and conforms to IPC/JEDEC J-STD-020B moisture sensitivity Level 1 - requiring no dry pack prior to reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum continuous DC or peak AC voltage the device blocks without conduction |
| V(BR) min/max | 10.0–11.1 V @ 1 mA - defines precise avalanche onset threshold for predictable turn-on |
| VC @ IPP | 15.4 V @ 194.8 A - maximum voltage seen by protected circuit during full 10/1000 µs surge |
| IPP | 194.8 A - peak surge current capability at 10/1000 µs waveform, defining system-level surge rating |
| TJ/TSTG | −55 °C to +150 °C - enables deployment in under-hood automotive, industrial PLC, and outdoor telecom enclosures |
| Standby leakage | ≤10 µA @ 9.0 V - ensures negligible power loss in always-on 24 VDC control circuits |
| Response time | <100 ps - faster than most IC-level ESD protection, enabling upstream rail-level defense |
Pinout & Package
MXLDA3KP9.0A is housed in a molded plastic DO-214AB (SMC) package with two terminals: Pin 1 (cathode) and Pin 2 (anode). Polarity is marked by a dot on the top surface; odd-numbered pins are cathodes per family convention. The package measures 21.03–22.05 mm × 6.86–7.87 mm × 8.64–9.65 mm (L×W×H) and weighs ~5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., +24 V rail); conducts when transient exceeds V(BR) |
| Pin 2 | Anode | Connected to ground reference; completes low-impedance path during clamping event |
Key Features
| Feature | Design Value |

IC Role / Device Role / Timing Role: Secondary protection layer after front-end fuse and MOV, ensuring sub-20 V clamping during ESD events. Use Value: 10 µA max leakage at 9 V avoids drift in precision 24-bit medical ADC references over 10-year service life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0A | 600 W rating, 10.0–11.1 V V(BR), same VWM but lower IPP (102 A) and VC (14.4 V) | Suitable for lower-energy environments (IEC 61000-4-2 only); not rated for IEC 61000-4-5 Class 4 | Select SMBJ9.0A where board space is constrained and surge threat level is limited to ESD/EFT |
| 1.5KE9.1A | 1500 W rating, 9.66–10.7 V V(BR), higher VC (15.5 V), axial lead TO-218 package | Requires through-hole mounting; lacks MIL-PRF-19500 screening and SMT compatibility | Choose 1.5KE9.1A only for legacy through-hole designs or where thermal mass from leads aids dissipation |
Compared with SMBJ9.0A and 1.5KE9.1A, MXLDA3KP9.0A delivers 2× and 2× higher peak power handling respectively, supports surface-mount automation, and offers qualified upscreening paths - making it the only choice for new high-reliability 3000 W surge protection designs.

FAQ
What is the clamping voltage of MXLDA3KP9.0A at its rated peak pulse current?
The MXLDA3KP9.0A 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 per the datasheet's Electrical Characteristics table and represents the highest voltage the protected circuit will experience during a full-rated surge event. Designers use this parameter to verify that downstream ICs remain within absolute maximum ratings.
Is MXLDA3KP9.0A RoHS compliant?
Yes, MXLDA3KP9.0A is RoHS compliant, indicated by the "e3" suffix in its full part marking per the nomenclature guide on page 2 of RF01243 Rev B. The device uses annealed matte-tin plating on terminations and meets Directive 2011/65/EU requirements. No lead content is present in the die attach, mold compound, or finish - confirmed by Microchip's material declarations.
Can MXLDA3KP9.0A be used in bidirectional configurations?
No, MXLDA3KP9.0A is unidirectional only. Bidirectional variants carry a "C" suffix (e.g., MXLDA3KP9.0CA). The MXLDA3KP9.0A conducts only when the cathode is positive relative to the anode - making it suitable for DC rail protection where polarity is fixed. Using it in AC or reversible-polarity circuits would require back-to-back pairing or selecting the C-suffix version.
What is the maximum operating temperature for MXLDA3KP9.0A?
The MXLDA3KP9.0A has a maximum junction and storage temperature of +150 °C, with derating beginning at 25 °C per the curve in Figure 3 of RF01243 Rev B. At 100 °C ambient, its peak pulse power drops to approximately 65% of the 3000 W rating. This allows reliable operation in sealed industrial enclosures or under-hood automotive locations where heatsinking is limited.
Does MXLDA3KP9.0A require pre-baking before reflow soldering?
No, MXLDA3KP9.0A does not require pre-baking. It is rated IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1, meaning it may be stored indefinitely at ≤30 °C/60% RH and placed directly into standard lead-free reflow profiles (e.g., JEDEC J-STD-020) without dry packing or baking - reducing manufacturing overhead and eliminating moisture-related popcorning risk.
