Product details
Overview
MXDA3KP36CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, featuring 36 V standoff voltage (VWM), 40.0–44.2 V breakdown voltage (V(BR)), 58.1 V maximum clamping voltage (VC) at 51.6 A peak pulse current, and <5 ns response time. It protects industrial power supplies and telecom interfaces against IEC61000-4-2/4-4/4-5 transients.
For engineers reviewing the MXDA3KP36CAE3 datasheet, MXDA3KP36CAE3 pinout, MXDA3KP36CAE3 application, or MXDA3KP36CAE3 equivalent, key selection criteria include bidirectional polarity, 36 V working voltage, 58.1 V clamping performance at 51.6 A, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening eligibility for high-reliability deployments.
Technical Context
This TVS array uses silicon avalanche diode technology to clamp fast-rising transients with sub-5 ns response. Its bidirectional construction enables symmetrical protection on AC-coupled or differential signal lines without polarity concerns.
Rated for 3000 W peak pulse power at 10/1000 µs waveform, it delivers 58.1 V clamping voltage at 51.6 A IPP while maintaining ≤2 µA standby current at 36 V VWM - enabling low-leakage protection in always-on systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous operating voltage before clamping begins |
| V(BR) min/max | 40.0–44.2 V @ 1 mA - ensures reliable turn-on above normal system peaks |
| VC @ IPP | 58.1 V @ 51.6 A - limits downstream voltage stress during 10/1000 µs surges |
| ID @ VWM | ≤2 µA - negligible leakage in standby, critical for battery-backed or low-power circuits |
| PPP | 3000 W @ 10/1000 µs - handles severe lightning-induced or inductive-switching energy |
| Response time | <5 ns - intercepts ESD events before sensitive ICs are damaged |
| Operating TJ | −55 °C to +150 °C - supports under-hood automotive and industrial ambient conditions |
Pinout & Package
MXDA3KP36CAE3 is housed in a DO-214AB (SMC) plastic package with void-free UL94V-0 epoxy body, matte-tin plated terminals, and polarity defined by dot marking indicating Pin 1 (cathode of first diode). Weight ≈5 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line; clamps positive transients to ground when referenced to Pin 2 |
| Pin 2 | Anode of Channel 1 / Cathode of Channel 2 | Common center tap; enables bidirectional clamping between Pins 1 and 3 |
| Pin 3 | Anode of Channel 2 | Connected to protected line; clamps negative transients to ground when referenced to Pin 2 |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional architecture | Protects AC or differential signals (e.g., RS-485, USB D+/D−) without external polarity management |
| 3000 W surge rating @ 10/1000 µs | Withstands secondary lightning surges per IEC61000-4-5 with 42 Ω source impedance (Class 1–4) |
| MIL-PRF-19500 upscreening option | Enables high-reliability qualification for aerospace and defense programs requiring lot traceability and 3σ ID screening |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and bake-out prior to reflow, reducing manufacturing cost and risk |
| RoHS-compliant (e3) | Meets global environmental compliance mandates without lead-free solder compatibility compromises |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package | Lower surge capacity suits consumer-grade power supplies but not Class 4 lightning testing | Select SMBJ36CA only where peak impulse current ≤14 A and 10/1000 µs energy is <100 mJ |
| 1.5KE36CA | 1500 W PPP, axial-leaded DO-201AD package, higher thermal resistance | Not suitable for high-density SMT layouts; requires through-hole assembly and board real estate | Choose 1.5KE36CA only for legacy designs with existing through-hole footprints and lower surge duty cycles |
Compared with SMBJ36CA and 1.5KE36CA, MXDA3KP36CAE3 provides 5× higher surge power handling in an SMT package with verified Class 4 lightning compliance - making it the sole option for new industrial and telecom designs requiring 3000 W transient immunity.

FAQ
What does the 'C' in MXDA3KP36CAE3 indicate?
The 'C' suffix denotes bidirectional polarity - meaning MXDA3KP36CAE3 provides symmetrical clamping for both positive and negative transients across its terminals. This is essential for protecting AC-coupled data lines like RS-485 or Ethernet PHY interfaces where voltage polarity reverses during normal operation.
Is MXDA3KP36CAE3 compliant with IEC61000-4-5 Class 4 testing?
Yes, MXDA3KP36CAE3 is rated for secondary lightning protection per IEC61000-4-5 with 42 Ω source impedance up to Class 4 (4 kV), as confirmed in the official Microsemi RF01243 datasheet. Its 3000 W peak pulse power and 58.1 V clamping voltage ensure downstream circuitry remains within safe operating limits during full-level surge events.
What is the maximum clamping voltage of MXDA3KP36CAE3 at its rated peak pulse current?
The maximum clamping voltage VC of MXDA3KP36CAE3 is 58.1 V at 51.6 A peak pulse current (IPP), measured under standard 10/1000 µs waveform conditions. This value defines the highest voltage seen by protected circuitry during worst-case surge events and is critical for ensuring compatibility with downstream IC absolute maximum ratings.
Does MXDA3KP36CAE3 require moisture-sensitive handling precautions?
No - MXDA3KP36CAE3 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it may be stored indefinitely at ambient conditions without dry packing or baking prior to reflow soldering. This eliminates process steps and reduces manufacturing risk compared to higher-MSL components.
Can MXDA3KP36CAE3 be used in automotive applications?
Yes, MXDA3KP36CAE3 operates from −55 °C to +150 °C and supports ISO 7637-2 load dump and pulse test requirements when applied to 12 V systems. Its bidirectional configuration and 58.1 V clamping make it suitable for LIN bus, sensor inputs, and body control module power rails where reliability under harsh thermal and electrical stress is mandatory.
