Product details
Overview
MXDA3KP33AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 33 V standoff voltage (VWM), 36.7–40.6 V breakdown voltage (V(BR)), and 53.3 V clamping voltage (VC) at 56.2 A peak pulse current. It delivers 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 industrial power supplies.
For engineers reviewing the MXDA3KP33AE3 datasheet, MXDA3KP33AE3 pinout, MXDA3KP33AE3 application, or MXDA3KP33AE3 equivalent, key selection criteria include verified 33 V VWM rating, 53.3 V VC @ 56.2 A, RoHS-compliant e3 marking, -55°C to +150°C operating range, and MIL-PRF-19500 upscreening eligibility for high-reliability deployments.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp transient overvoltages within <100 ps response time. Its unidirectional polarity and 33 V VWM are optimized for DC power rail protection where reverse voltage exposure is not expected.
The device meets IEC61000-4-5 surge immunity with 42 Ω source impedance across Class 1–4, supports 10/1000 μs waveform testing at 3000 W, and maintains stable clamping performance under thermal derating per Figure 3 - critical for sustained operation in enclosed industrial enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 33 V - maximum continuous DC operating voltage before clamping initiates |
| V(BR) min/max | 36.7–40.6 V @ 1 mA - ensures reliable avalanche conduction onset across process variation |
| VC @ IPP | 53.3 V @ 56.2 A - limits downstream component stress during 10/1000 μs surges |
| PPP | 3000 W @ 10/1000 μs - sustains high-energy transients without failure |
| ID @ VWM | 2 μA max - negligible leakage in standby, preserving low-power system integrity |
| TJ/TSTG | -55°C to +150°C - enables deployment in automotive under-hood or industrial motor drive environments |
| RoHS | e3 marking - lead-free matte-tin plating compliant with EU Directive 2011/65/EU |
Pinout & Package
MXDA3KP33AE3 is housed in a void-free thermosetting epoxy package (UL94V-0 rated) with dual anode-cathode configuration. Pin 1 is marked by a dot on top; odd-numbered pins are cathodes per standard TVS polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Connected to protected line; conducts surge current to ground when V > V(BR) |
| Pin 2 | Anode (Channel 1) | Connected to ground reference; completes clamping path for unidirectional operation |
| Pin 3 | Cathode (Channel 2) | Second independent clamping channel for dual-rail or redundant protection |
| Pin 4 | Anode (Channel 2) | Ground return for Channel 2; enables simultaneous protection of two DC lines |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Withstands high-energy surges common in industrial motor drives and power supply inputs |
| 100 ps response time | Clamps ESD events before sensitive logic or analog circuitry is damaged |
| MIL-PRF-19500 upscreening option | Enables qualification for aerospace, defense, and medical systems requiring lot traceability and 3σ ID screening |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing assembly cost and risk |
| UL94V-0 epoxy body | Prevents flame propagation in fault conditions, meeting safety standards for enclosed equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A | 600 W PPP rating, SMA package, 53.3 V VC @ 11.8 A - lower energy handling | Suitable for low-power signal lines; insufficient for 3000 W industrial surges | Select MXDA3KP33AE3 when 3000 W surge immunity and dual-channel layout are required. |
| SMCJ33A | 1500 W PPP rating, SMC package, 53.3 V VC @ 28.1 A - half the energy capacity | Acceptable for Class 2–3 IEC61000-4-5; fails Class 4 validation at 42 Ω | Choose MXDA3KP33AE3 for full Class 1–4 compliance and MIL-PRF-19500 upscreening path. |
Compared with SMAJ33A and SMCJ33A, MXDA3KP33AE3 provides double the peak pulse power (3000 W vs. 600/1500 W), dual-channel integration in one package, and direct eligibility for high-reliability screening - making it the only option qualified for Class 4 secondary lightning protection in industrial control cabinets.

FAQ
What is the clamping voltage of MXDA3KP33AE3 at its rated peak pulse current?
MXDA3KP33AE3 has a maximum clamping voltage (VC) of 53.3 V at 56.2 A peak pulse current (IPP), measured under 10/1000 μs waveform conditions. This value ensures protected circuits remain below safe voltage thresholds during high-energy transients. The MXDA3KP33AE3 datasheet specifies this parameter in Table "ELECTRICAL CHARACTERISTICS" on Page 3, confirming consistent clamping behavior across production lots.
Is MXDA3KP33AE3 RoHS-compliant and what does the 'e3' suffix indicate?
Yes, MXDA3KP33AE3 is RoHS-compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide (Page 2). The 'e3' denotes annealed matte-tin plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity - eliminating dry-pack requirements and enabling standard reflow profiles. This compliance is documented in RF01243 Rev B, Section "MECHANICAL and PACKAGING".
Does MXDA3KP33AE3 support bidirectional transient suppression?
No, MXDA3KP33AE3 is a unidirectional TVS array, indicated by the absence of 'C' in its part number (e.g., MDA3KP33CA would be bidirectional). Its polarity follows standard convention: odd pins are cathodes, even pins are anodes. This configuration is intended for DC rail protection where reverse voltage is not expected, as specified in the "POLARITY" section of RF01243 Rev B, Page 2.
What is the maximum operating temperature range for MXDA3KP33AE3?
MXDA3KP33AE3 operates from -55°C to +150°C for both junction and storage temperatures, per the "MAXIMUM RATINGS" table on Page 2 of RF01243 Rev B. This extended range supports deployment in under-hood automotive modules, industrial variable-frequency drives, and outdoor renewable energy equipment where ambient temperatures exceed standard commercial limits.
Can MXDA3KP33AE3 be used for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MXDA3KP33AE3 is explicitly rated for IEC61000-4-5 Class 1–4 secondary lightning protection with 42 Ω source impedance, as stated in the "APPLICATIONS / BENEFITS" section on Page 1 of RF01243 Rev B. Its 3000 W peak pulse power and validated clamping performance at 56.2 A enable full compliance without additional series impedance or derating.
