Product details
Overview
MADA3KP14AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array designed for high-reliability secondary lightning and ESD protection in industrial power interfaces. It features a 14 V reverse standoff voltage (VWM), 15.6–17.2 V breakdown voltage (V(BR)), 23.2 V maximum clamping voltage at 129.4 A peak pulse current, and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP14AE3 datasheet, MADA3KP14AE3 pinout, MADA3KP14AE3 application, or MADA3KP14AE3 equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω source impedance, 100 ps response time, RoHS-compliant e3 termination, and MIL-PRF-19500 upscreening eligibility.
Technical Context
The MADA3KP14AE3 is a single-channel unidirectional TVS diode optimized for fast clamping of high-energy transients in DC power rails and signal lines. Its silicon avalanche structure delivers sub-100 ps response and clamps at 23.2 V under 10/1000 µs 129.4 A surge, meeting IEC61000-4-2 (ESD), -4-4 (EFT), and -4-5 (lightning) immunity requirements.
It uses a void-free thermosetting epoxy package rated UL94V-0, with tin-lead or matte-tin plating per MIL-STD-750 Method 2026. Polarity is defined by dot marking; Pin 1 is cathode. Standby leakage is ≤2 µA at 14 V, and thermal derating begins above 25 °C per Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 14 V - Maximum continuous DC operating voltage before clamping initiates |
| V(BR) min/max | 15.6–17.2 V @ 1 mA - Ensures reliable avalanche conduction onset within tight tolerance |
| VC @ IPP | 23.2 V @ 129.4 A - Clamping voltage limits downstream IC stress during full 3 kW surge |
| PPP | 3000 W @ 10/1000 µs - Sustains high-energy surges without failure in industrial environments |
| ID @ VWM | ≤2 µA - Negligible leakage preserves battery life and low-power rail integrity |
| TJ range | –55 °C to +150 °C - Supports operation in harsh under-hood, aerospace, and industrial control enclosures |
| Response time | <100 ps - Faster than most microcontrollers' interrupt latency, enabling pre-damage suppression |
Pinout & Package
Package: DO-214AB (SMC) molded plastic case, UL94V-0 rated, ~5 g weight, dimensions per Page 6 (A=21.03–22.05 mm, B=6.86–7.87 mm, C=8.64–9.65 mm). Marked with date code and part number; polarity indicated by dot on top; Pin 1 = cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line; conducts surge current to ground when voltage exceeds V(BR) |
| Pin 2 | Anode | Connected to system ground reference; completes low-impedance path for transient energy dissipation |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables single-device protection against IEC61000-4-5 Level 4 surges (4 kV, 42 Ω source) without parallel staging |
| RoHS-compliant e3 termination | Matte-tin plating ensures lead-free assembly compatibility and solder joint reliability per J-STD-020B Level 1 |
| MIL-PRF-19500 upscreening option | Supports high-reliability programs requiring lot traceability, 3σ ID screening, and conformance inspection |
| 100 ps response time | Clamps before ESD events (IEC61000-4-2 ±8 kV contact) can damage sensitive gate oxides in MOSFETs or MCUs |
| UL94V-0 epoxy body | Prevents flame propagation in enclosed power supplies and motor drives under fault conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ14A | Same DO-214AB package, 14 V VWM, but 25.1 V VC @ 124 A; lower PPP (400 W) | Not suitable for IEC61000-4-5 Class 4; limited to Class 2/3 or low-energy ESD/EFT only | Select MADA3KP14AE3 where 3000 W surge handling and MIL-PRF-19500 screening are required |
| Vishay SM8S14A | DO-218AB package (larger), 14 V VWM, 23.2 V VC @ 132.5 A; PPP = 6600 W | Higher power rating but incompatible footprint; requires PCB redesign and higher mounting force | Choose MADA3KP14AE3 for drop-in replacement in existing SMC-layout designs with 3 kW requirement |
Compared with SMAJ14A and SM8S14A, the MADA3KP14AE3 uniquely balances 3000 W capability, DO-214AB compatibility, and military-grade screening readiness-making it optimal for space-constrained, high-surge industrial systems where layout reuse and qualification traceability are critical.

FAQ
What is the clamping voltage of MADA3KP14AE3 under maximum surge conditions?
The MADA3KP14AE3 has a maximum clamping voltage (VC) of 23.2 V at its rated peak pulse current (IPP) of 129.4 A under 10/1000 µs waveform conditions. This value is guaranteed across temperature and ensures protected circuits remain below critical overvoltage thresholds during worst-case transients. The MADA3KP14AE3 achieves this via controlled avalanche breakdown in its silicon junction.
Is MADA3KP14AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, MADA3KP14AE3 is RoHS compliant. The 'e3' suffix explicitly denotes matte-tin plating per JEDEC Standard J-STD-020B, confirming lead-free termination and compatibility with standard reflow profiles. This specification is verified in the Microsemi RF01243 Rev B datasheet and applies to all units shipped with the e3 marking.
Can MADA3KP14AE3 be used for bidirectional transient protection?
No, MADA3KP14AE3 is unidirectional only. Its part number lacks the 'C' suffix (e.g., MDA3KP14CE3), which designates bidirectional construction. The MADA3KP14AE3 conducts only when cathode voltage exceeds anode by ≥V(BR); it blocks reverse current beyond VWM. For AC or dual-polarity rails, a bidirectional variant must be selected.
What is the maximum operating temperature range for MADA3KP14AE3?
The MADA3KP14AE3 supports a junction and storage temperature range of –55 °C to +150 °C. Derating of peak pulse power begins above 25 °C per the curve in Figure 3 of the RF01243 datasheet. At 125 °C, it retains ~60% of its 3000 W rating, making it suitable for under-hood automotive and industrial control cabinet deployments.
Does MADA3KP14AE3 require a heatsink for standard 3000 W surge handling?
No, MADA3KP14AE3 does not require an external heatsink for single-event 3000 W surge handling. Its DO-214AB package and silicon design dissipate transient energy through short-duration avalanche conduction, not steady-state thermal load. However, repeated surges at high duty cycle (>0.05%) may necessitate board-level copper thermal spreading per Microsemi's layout guidelines.
