Product details
Overview
MADA3KP11CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount package, designed for high-reliability surge protection of sensitive electronics. It features a 11 V reverse standoff voltage (VWM), 12.2–13.5 V breakdown voltage (V(BR)), 18.2 V maximum clamping voltage (VC) at 164.8 A peak pulse current, and operates from −55 °C to +150 °C - used in industrial power supplies, telecom line interfaces, and automotive ECUs against lightning-induced transients.
For engineers reviewing the MADA3KP11CAE3 datasheet, MADA3KP11CAE3 pinout, MADA3KP11CAE3 application, or MADA3KP11CAE3 equivalent, key selection criteria include bidirectional polarity, 10/1000 µs surge rating, IEC61000-4-5 Class 1–4 secondary lightning compliance, low standby current (≤5 µA), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
MADA3KP11CAE3 implements an avalanche diode-based TVS structure with sub-5 ns response time, enabling suppression of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and lightning surges (IEC61000-4-5). Its bidirectional configuration allows symmetrical clamping across both polarities without external circuitry.
The device is rated for 3000 W peak pulse power at 10/1000 µs waveform, with thermal derating above 25 °C per Figure 3. Junction temperature range (−55 °C to +150 °C) and moisture sensitivity level 1 support extended-life deployment in harsh environments without dry-pack handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11 V - maximum continuous operating voltage before clamping begins; matches 12 V rail systems with margin. |
| V(BR) min/max | 12.2–13.5 V @ 1 mA - verified avalanche threshold ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 18.2 V @ 164.8 A - limits downstream voltage stress during 3000 W surge, protecting ICs with ≤20 V absolute max ratings. |
| ID @ VWM | ≤5 µA - negligible leakage at operating voltage, avoiding power loss or false triggering in low-power circuits. |
| PPP | 3000 W @ 10/1000 µs - meets IEC61000-4-5 Class 4 with 42 Ω source impedance for secondary lightning immunity. |
| TJ/TSTG | −55 °C to +150 °C - supports under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| RoHS | e3 marking - lead-free matte-tin termination compliant with EU Directive 2011/65/EU and JEDEC J-STD-020B Level 1. |
Pinout & Package
Package: Surface-mount DO-214AB (SMC) molded thermosetting epoxy case, UL94V-0 rated, ~5 g weight, with polarity defined by dot marking on top indicating Pin 1 (cathode for unidirectional variants; symmetric terminals for bidirectional MADA3KP11CAE3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (Bidirectional) | One terminal of symmetrical avalanche junction; connects to protected line (e.g., RS-485 A or CAN H). |
| Pin 2 | Cathode (Bidirectional) | Second terminal of symmetrical junction; connects to reference plane (e.g., ground or RS-485 B/CAN L). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential lines (e.g., Ethernet PHY, RS-485) without polarity constraints. |
| 3000 W surge rating | Withstands repeated 10/1000 µs transients up to 164.8 A, exceeding IEC61000-4-5 Class 4 requirements for telecom infrastructure. |
| Sub-5 ns response time | Clamps within 5 ns of transient onset, limiting energy delivery to downstream components before damage occurs. |
| MIL-PRF-19500 screening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and conformance inspection for aerospace/defense applications. |
| Level 1 moisture sensitivity | Eliminates bake-out requirement prior to reflow; compatible with standard SMT assembly processes per IPC/JEDEC J-STD-020B. |
Applications

IC Role / Device Role / Timing Role: Standoff-rated protector on analog front-end inputs measuring up to 1000 V DC strings. Use Value: 11 V VWM provides margin over 12 V auxiliary supply while clamping induced surges to safe levels for 16-bit ADC drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | 600 W PPP rating, same VWM and bidirectional polarity, DO-214AA package (smaller footprint). | Limited to Class 2 lightning per IEC61000-4-5; insufficient for 3000 W telecom or industrial surge events. | Select when space-constrained and surge threat is limited to ESD/EFT only. |
| 1.5KE11CA | 1500 W PPP, axial-leaded DO-15 package, higher clamping voltage (20.1 V), no RoHS e3 marking. | Not suitable for automated SMT assembly; thermal performance inferior due to leadframe vs. SMC thermal path. | Choose only for legacy through-hole designs where rework tolerance and manual assembly are acceptable. |
Compared with SMBJ11CA and 1.5KE11CA, MADA3KP11CAE3 delivers triple the surge power handling, SMT compatibility, and certified RoHS compliance - making it the sole choice for new industrial and telecom designs requiring Class 4 lightning immunity and production scalability.

FAQ
What is the clamping voltage of MADA3KP11CAE3 at its rated peak pulse current?
MADA3KP11CAE3 has a maximum clamping voltage (VC) of 18.2 V at its peak pulse current (IPP) of 164.8 A under 10/1000 µs waveform conditions. This value is measured per IEC61000-4-5 test methodology and guarantees that downstream circuitry sees no more than 18.2 V during a full 3000 W surge event, protecting components with 20 V absolute maximum ratings.
Is MADA3KP11CAE3 suitable for IEC61000-4-5 Class 4 secondary lightning protection?
Yes, MADA3KP11CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection with 42 Ω source impedance, as confirmed in the Applications section of Microsemi's RF01243 datasheet. Its 3000 W peak pulse power and 164.8 A IPP meet the 4 kV test level requirement, making MADA3KP11CAE3 appropriate for telecom central office and industrial field equipment.
Does MADA3KP11CAE3 require special handling due to moisture sensitivity?
No, MADA3KP11CAE3 is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions and processed using standard reflow profiles without baking. The e3 marking confirms RoHS-compliant matte-tin plating, and the void-free epoxy body eliminates moisture ingress risk during soldering.
How does the bidirectional design of MADA3KP11CAE3 affect its use in differential signal lines?
The bidirectional construction of MADA3KP11CAE3 enables symmetrical clamping across both polarities, allowing direct placement across differential pairs like RS-485 or CAN without polarity concerns. Unlike unidirectional TVS arrays, MADA3KP11CAE3 protects against positive and negative transients equally, preserving common-mode rejection and eliminating the need for dual devices or external bias networks.
Can MADA3KP11CAE3 replace older 1.5KE11CA parts in existing designs?
MADA3KP11CAE3 is not a drop-in replacement for 1.5KE11CA due to different package (DO-214AB vs. DO-15), higher power rating (3000 W vs. 1500 W), and SMT-only assembly. While electrical parameters like VWM and polarity match, PCB layout changes are required. For redesigns targeting improved surge immunity and automated manufacturing, MADA3KP11CAE3 offers superior performance and compliance - but legacy through-hole boards must retain 1.5KE11CA or undergo mechanical revision.
