Product details
Overview
MXDA3KP17A from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability protection of voltage-sensitive circuits against ESD, EFT, inductive switching transients, and secondary lightning surges per IEC61000-4-2/4-4/4-5. It features a 17 V standoff voltage (VWM), 18.9–20.9 V breakdown range (V(BR)), 27.6 V clamping voltage at 106.6 A peak pulse current, and operates from –55 °C to +150 °C.
For engineers reviewing the MXDA3KP17A datasheet, MXDA3KP17A pinout, MXDA3KP17A application, or MXDA3KP17A equivalent, this device is selected for robust overvoltage protection in telecom power interfaces, industrial control I/O modules, and automotive body electronics where fast response (<100 ps), high surge capability, and MIL-PRF-19500 upscreening options are required.
Technical Context
The MXDA3KP17A is a single-channel unidirectional TVS diode optimized for clamping transients with a 10/1000 µs waveform. Its silicon avalanche structure delivers sub-100 ps response time and guarantees clamping at ≤27.6 V when subjected to 106.6 A peak impulse current, enabling reliable protection of downstream 18–24 V logic and interface ICs.
It complies with IEC61000-4-2 (ESD ±30 kV air/±30 kV contact), IEC61000-4-4 (EFT 4 kV), and IEC61000-4-5 (lightning surge up to Class 4 with 42 Ω source impedance). Standby leakage is limited to ≤2 µA at 17 V, ensuring minimal impact on system quiescent power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - Maximum continuous DC or peak AC operating voltage before clamping begins |
| V(BR) min/max | 18.9–20.9 V @ 1 mA - Ensures predictable avalanche initiation across temperature and lot variation |
| VC @ IPP | 27.6 V @ 106.6 A - Clamping voltage during full 3000 W surge, protecting 24 V-rated components |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy transients without failure under defined waveform |
| ID @ VWM | ≤2 µA - Negligible standby current, critical for battery-backed or low-power sensor nodes |
| TJ/TSTG | –55 °C to +150 °C - Supports operation in under-hood automotive and industrial environments |
Pinout & Package
MXDA3KP17A uses a 2-pin DO-214AB (SMC) package with cathode-marked lead configuration: Pin 1 = Cathode, Pin 2 = Anode. The void-free UL94V-0 epoxy body enables reflow soldering at 260 °C for 10 s and supports moisture sensitivity level 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., 17 V rail); clamps positive transients to ground via anode |
| Pin 2 | Anode | Typically tied to system ground or low-impedance return path; completes conduction path during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables single-device protection against severe lightning-induced surges in telecom and industrial power inputs |
| Sub-100 ps response time | Clamps ESD events before sensitive CMOS inputs can be damaged, meeting IEC61000-4-2 Level 4 |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring wafer lot traceability, 3σ ID screening, and conformance inspection |
| RoHS-compliant e3 marking | Meets global environmental compliance requirements without compromising surge performance or thermal derating |
Applications
| Telecom Power Input Protection | Industrial PLC Digital I/O |
|---|---|
Use Scenario: Protecting 24 V DC power input of base station remote radio units from induced lightning surges and hot-swap transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping positive-going transients on the VIN rail to ground. Use Value: Limits voltage to ≤27.6 V during 106.6 A surges, preventing damage to upstream DC/DC controllers and downstream PMICs. | Use Scenario: Shielding 24 V digital input channels of programmable logic controllers from inductive kickback and EFT noise. IC Role / Device Role / Timing Role: Fast-acting shunt protector placed between field-side signal and isolation barrier. Use Value: Sub-100 ps response ensures clamping occurs before transient energy couples into optocoupler or digital isolator inputs. |
| Automotive Body Control Module | Medical Diagnostic Equipment Power Rails |
Use Scenario: Safeguarding LIN bus power supply and window motor driver circuits against load dump and jump-start transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12–18 V distribution rails feeding microcontrollers and drivers. Use Value: 150 °C junction rating and 2 µA leakage allow direct placement near heat-generating power stages without thermal drift issues. | Use Scenario: Securing isolated 17–24 V auxiliary power rails in portable ultrasound and imaging systems. IC Role / Device Role / Timing Role: Secondary surge suppression stage after front-end filters, before LDO regulators. Use Value: Low standby current preserves battery life in battery-operated devices while maintaining IEC60601-1 ESD immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A | Lower PPP (600 W), same VWM (17 V), DO-214AA (SMB) package, 27.6 V VC @ 21.5 A | Not suitable for IEC61000-4-5 Class 3/4 lightning; limited to ESD/EFT and low-energy switching transients | Select SMBJ17A only when surge energy is <600 W and board space constraints favor smaller SMB footprint. |
| 1.5KE17A | Higher PPP (1500 W), axial-leaded DO-201AE package, 27.7 V VC @ 54.3 A, no RoHS e3 marking by default | Requires through-hole assembly; lacks MIL-PRF-19500 screening options and moisture level 1 rating | Choose 1.5KE17A for cost-sensitive, non-RoHS or non-surface-mount legacy designs where reflow compatibility is not required. |
Compared with SMBJ17A and 1.5KE17A, MXDA3KP17A delivers 5× higher surge power handling in a surface-mount package with certified RoHS compliance, MIL-PRF-19500 upscreening support, and guaranteed low-leakage performance across extended temperature-making it the preferred choice for new high-reliability industrial and telecom designs.

FAQ
What is the clamping voltage of MXDA3KP17A at its rated peak pulse current?
The MXDA3KP17A has a maximum clamping voltage (VC) of 27.6 V at its rated peak pulse current (IPP) of 106.6 A under 10/1000 µs waveform conditions. This value is guaranteed across manufacturing lots and temperature extremes, ensuring consistent protection margin for 24 V systems. The MXDA3KP17A datasheet specifies this as the upper limit for design margining.
Is MXDA3KP17A RoHS compliant and what does the 'e3' marking indicate?
Yes, MXDA3KP17A is RoHS compliant, indicated by the 'e3' suffix in its full marking per Microsemi's nomenclature. The 'e3' denotes annealed matte-tin plating per J-STD-020B, confirming lead-free termination and compliance with EU Directive 2011/65/EU. This applies to all standard production lots of MXDA3KP17A shipped after 2019.
Can MXDA3KP17A be used for bidirectional transient protection?
No, MXDA3KP17A is unidirectional. Its part number lacks the 'C' suffix (e.g., MDA3KP17CA), which Microsemi reserves exclusively for bidirectional variants. MXDA3KP17A conducts only for positive transients on the cathode (Pin 1) relative to anode (Pin 2); reverse polarity events are not clamped. For bidirectional protection, select MDA3KP17CA instead.
What is the maximum operating temperature range for MXDA3KP17A?
MXDA3KP17A is rated for junction and storage temperatures from –55 °C to +150 °C. This wide range is validated per Microsemi's qualification testing and supports deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. Derating of peak pulse power begins above 25 °C per Figure 3 in the MXDA3KP17A datasheet.
Does MXDA3KP17A require dry-pack packaging or moisture sensitivity handling?
No, MXDA3KP17A has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored indefinitely at ambient conditions without baking or dry-pack requirements. This eliminates moisture-related popcorning risk during reflow soldering and simplifies manufacturing logistics compared to higher-MSL components.
