Product details
Overview
MXLDA3KP17AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 17 V standoff voltage (VWM), 18.9–20.9 V breakdown voltage (V(BR)), and 27.6 V clamping voltage (VC) at 106.6 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 MXLDA3KP17AE3 datasheet, MXLDA3KP17AE3 pinout, MXLDA3KP17AE3 application, or MXLDA3KP17AE3 equivalent, key selection criteria include verified 17 V VWM tolerance, 27.6 V VC @ 106.6 A, RoHS-compliant e3 marking, MIL-PRF-19500 upscreening eligibility, and 100 ps response time - all critical for high-reliability industrial power rail protection.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transients within 100 ps, delivering 3000 W peak pulse power at 10/1000 µs waveform. Its unidirectional polarity and cathode-defined odd-pin configuration enable precise placement on DC-biased lines such as PoE injectors and base station DC feeds.
Designed for vertical mounting in high-density PCB layouts, MXLDA3KP17AE3 features void-free UL94V-0 epoxy packaging, tin-lead or matte-tin terminations compliant with MIL-STD-750 Method 2026, and full lot traceability supporting aerospace and defense qualification requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - maximum continuous operating voltage before clamping begins; matches 15 V nominal DC rails with 13% margin |
| V(BR) min/max | 18.9–20.9 V - guaranteed avalanche onset range at 1 mA; ensures consistent turn-on across temperature and lot variance |
| VC @ IPP | 27.6 V at 106.6 A - clamped voltage during worst-case 10/1000 µs surge; limits downstream IC stress to safe levels |
| PPP | 3000 W - peak pulse power handling at 10/1000 µs; meets IEC61000-4-5 Level 4 with 42 Ω source impedance |
| Response time | <100 ps - enables effective suppression of ESD events (IEC61000-4-2 ±8 kV contact) before system damage occurs |
| RoHS | e3 marking - lead-free matte-tin plating compliant with EU Directive 2011/65/EU and JEDEC J-STD-020B Level 1 moisture sensitivity |
| TJ/TSTG | −55 °C to +150 °C - supports operation in extended-temperature industrial enclosures and outdoor telecom cabinets |
Pinout & Package
MXLDA3KP17AE3 uses a 3-pin TO-277A (SMB) package with vertical mounting orientation, void-free UL94V-0 epoxy body, and polarity defined by dot-marked Pin 1 (cathode). Terminals are tin-lead or annealed matte-tin plated for reliable solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; clamps positive transients to ground when voltage exceeds V(BR) |
| Pin 2 | Anode | Common ground reference; must be low-inductance connection to system earth or chassis ground |
| Pin 3 | Cathode | Second protected line channel; enables dual-line protection (e.g., differential pair or redundant supply) |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse rating | Enables single-device protection against IEC61000-4-5 Level 4 surges (4 kV, 42 Ω source) without derating or parallel devices |
| 100 ps response time | Prevents latch-up or gate oxide rupture in downstream MOSFETs and ICs during sub-nanosecond ESD events |
| MIL-PRF-19500 screening option | Supports high-reliability programs requiring wafer lot traceability, 3σ ID screening, and conformance inspection |
| UL94V-0 epoxy package | Provides flame-retardant mechanical integrity in enclosed power systems where thermal runaway risk exists |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost and cycle time |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A | 600 W PPP rating, 20.0 V V(BR) min, 27.7 V VC @ 21.2 A - lower power handling and current capacity | Targeted at consumer-grade 12–24 V systems; insufficient for IEC61000-4-5 Level 4 compliance | Select SMAJ17A only for cost-sensitive, non-certified designs with <1 kW surge exposure |
| SMCJ17A | 1500 W PPP rating, 18.9 V V(BR) min, 27.6 V VC @ 54.3 A - half the peak power and current capability of MXLDA3KP17AE3 | Suitable for Level 2–3 IEC61000-4-5 (2 kV–3 kV); requires derating above 85 °C ambient | Choose SMCJ17A when board space allows larger SMC package and system surge threat level is ≤3 kV |
Compared with SMAJ17A and SMCJ17A, MXLDA3KP17AE3 delivers double the pulse power of SMCJ17A and five times that of SMAJ17A - enabling single-device compliance with IEC61000-4-5 Level 4 in compact SMB footprint without parallel staging or thermal compromise.

FAQ
What is the clamping voltage of MXLDA3KP17AE3 at its rated peak pulse current?
The MXLDA3KP17AE3 has a maximum clamping voltage (VC) of 27.6 V at 106.6 A peak pulse current (IPP), measured under 10/1000 µs waveform conditions. This value ensures downstream components see no more than 27.6 V during worst-case surge events, making MXLDA3KP17AE3 suitable for protecting 36 V-rated power stages. The clamping performance is guaranteed across −55 °C to +150 °C operating junction temperature.
Is MXLDA3KP17AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MXLDA3KP17AE3 is RoHS compliant, as confirmed by the 'e3' suffix in its part number. Per Microsemi documentation, 'e3' denotes matte-tin plating meeting EU Directive 2011/65/EU requirements and IPC/JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating the need for dry packing or baking before reflow. MXLDA3KP17AE3's e3 marking applies to both termination finish and packaging materials.
Can MXLDA3KP17AE3 be used for bidirectional transient suppression?
No, MXLDA3KP17AE3 is a unidirectional TVS device, as indicated by the absence of 'C' in its part number (e.g., MDA3KP17CA would be bidirectional). Its pinout defines Pins 1 and 3 as cathodes and Pin 2 as common anode, enabling clamping only of positive-going transients relative to ground. For bidirectional protection, MXLDA3KP17AE3 must be paired with a complementary device or replaced with MDA3KP17CE3.
What is the standoff voltage (VWM) rating of MXLDA3KP17AE3 and how does it relate to system design?
MXLDA3KP17AE3 has a rated working standoff voltage (VWM) of 17 V - the maximum continuous DC or RMS voltage it can withstand without entering avalanche conduction. This rating aligns with 15 V nominal systems (e.g., industrial sensors) providing ~13% margin above operating voltage. Exceeding 17 V continuously risks premature wear or leakage increase, so MXLDA3KP17AE3 must be applied only where peak system voltage remains ≤17 V.
Does MXLDA3KP17AE3 require special PCB layout considerations?
Yes, MXLDA3KP17AE3 demands low-inductance layout: short, wide traces between Pins 1/3 and protected lines, and direct low-impedance connection from Pin 2 to system ground plane. Its 100 ps response time means even 1 nH of trace inductance adds ~100 mV/kA surge overshoot. The device's TO-277A package also requires vertical mounting clearance (≥2.67 mm height) and adherence to the specified pad layout on page 7 of RF01243 Rev B to ensure thermal and mechanical reliability.
