Product details
Overview
MXLDA3KP16AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 16 V standoff voltage (VWM), 17.8–19.7 V breakdown range (V(BR)), and 26.0 V maximum clamping voltage (VC) at 115.4 A peak pulse current. It provides secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in telecom power interfaces.
For engineers reviewing the MXLDA3KP16AE3 datasheet, MXLDA3KP16AE3 pinout, MXLDA3KP16AE3 application, or MXLDA3KP16AE3 equivalent, key selection criteria include its 16 V working standoff, 26.0 V clamping performance at 115.4 A, RoHS-compliant e3 marking, unidirectional polarity, and MIL-PRF-19500 upscreening capability for high-reliability aerospace and industrial systems.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp fast transients with sub-100 ps response time in unidirectional configuration. It operates across –55 °C to +150 °C junction temperature and is rated for 3000 W peak pulse power under 10/1000 µs waveform with ≤0.05% duty cycle.
Clamping occurs at 26.0 V maximum when subjected to 115.4 A IPP, limiting downstream voltage stress while maintaining <2 µA standby leakage at 16 V VWM. Its void-free UL94V-0 epoxy package supports reflow soldering at 260 °C for 10 s and enables direct integration into DC power rails and signal line protection networks.

Pinout & Package
MXLDA3KP16AE3 is housed in a vertical surface-mount plastic package (case outline per RF01243, Page 6) with 2 terminals: Pin 1 (cathode) and Pin 2 (anode). Polarity is marked by a dot on top of the package; odd-numbered pins are cathodes per family convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., +12 V rail); conducts during overvoltage to shunt current to ground |
| Pin 2 | Anode | Typically tied to system ground; completes low-impedance path for surge current dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | 600 W PPP rating, SMA package, 25.0 V VC @ 24.7 A IPP | Lower energy handling; suited for board-level ESD only, not secondary lightning | Select MXLDA3KP16AE3 when >100 A surge current or IEC61000-4-5 compliance is required |
| SMCJ16A | 1500 W PPP rating, SMC package, 25.0 V VC @ 60.7 A IPP | Mid-tier energy capacity; lacks MIL-PRF-19500 upscreening option | Choose MXLDA3KP16AE3 for aerospace-grade reliability or where 3000 W surge margin is critical |
Compared with SMAJ16A and SMCJ16A, MXLDA3KP16AE3 delivers double the peak pulse power and certified high-reliability screening-making it the only choice for mission-critical telecom infrastructure and defense electronics requiring validated 3000 W transient immunity.

FAQ
What is the clamping voltage of MXLDA3KP16AE3 at its rated peak pulse current?
The MXLDA3KP16AE3 has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current (IPP) of 115.4 A under 10/1000 µs waveform conditions. This value is measured per standard test methods defined in the RF01243 datasheet and ensures downstream components see no more than 26.0 V during worst-case surge events. The MXLDA3KP16AE3 maintains this clamping performance across its full operating temperature range.
Is MXLDA3KP16AE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP16AE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number. Per Microsemi's nomenclature (RF01243, Page 2), 'e3' denotes lead-free matte-tin plating on terminals, fully compliant with EU Directive 2011/65/EU. The device uses void-free UL94V-0 epoxy packaging and meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. MXLDA3KP16AE3 is qualified for lead-free reflow soldering at 260 °C for 10 seconds.
Can MXLDA3KP16AE3 be used for bidirectional transient protection?
No, MXLDA3KP16AE3 is a unidirectional TVS device, as indicated by the absence of 'C' in its part number (per RF01243, Page 2: 'C = Bidirectional'). Its polarity is fixed: Pin 1 is cathode, Pin 2 is anode. For bidirectional protection at 16 V standoff, the correct variant is MXLDA3KP16CE3. Using MXLDA3KP16AE3 in AC-coupled or bipolar signal paths will result in forward conduction during negative excursions, potentially damaging the device or circuit.
What is the maximum steady-state leakage current of MXLDA3KP16AE3 at its rated standoff voltage?
The MXLDA3KP16AE3 exhibits a maximum standby current (ID) of 2 µA when biased at its rated reverse standoff voltage (VWM) of 16 V, measured at 25 °C per RF01243 datasheet (Page 3, Electrical Characteristics table). This ultra-low leakage preserves power efficiency in always-on systems such as battery-backed sensors or remote monitoring nodes. The MXLDA3KP16AE3 maintains <10 µA ID across its full –55 °C to +150 °C operating junction temperature range.
Does MXLDA3KP16AE3 support MIL-PRF-19500 high-reliability screening?
Yes, MXLDA3KP16AE3 supports optional MIL-PRF-19500 upscreening per Microsemi's documentation (RF01243, Page 1). Screening includes wafer lot traceability, 3σ statistical screening on standby current (ID), and conformance inspections aligned with Class K or Class H requirements. While the base MXLDA3KP16AE3 is commercial-grade, the screened version is designated with additional suffixes and is intended for aerospace, defense, and critical infrastructure applications where failure is not acceptable. MXLDA3KP16AE3 forms the foundation for these qualified variants.
