Product details
Overview
MADA3KP10CA from Microsemi is a bidirectional 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 10 V reverse standoff voltage (VWM), 11.1–12.3 V breakdown voltage (V(BR)), 17.0 V maximum clamping voltage at 176.4 A peak pulse current, and operates from −55 °C to +150 °C junction temperature.
For engineers reviewing the MADA3KP10CA datasheet, MADA3KP10CA pinout, MADA3KP10CA application, or MADA3KP10CA equivalent, key selection criteria include IEC61000-4-5 Class 1–4 compliance with 42 Ω/12 Ω/2 Ω source impedances, bidirectional polarity, RoHS-compliant e3 marking, and 10/1000 µs surge rating - all critical for robust front-end protection in telecom power supplies and motor drive gate drivers.
Technical Context
The MADA3KP10CA implements a silicon avalanche diode structure optimized for sub-5 ns response time and low clamping ratio (VC/V(BR) ≈ 1.45). Its bidirectional configuration enables symmetrical transient suppression on AC-coupled or floating signal/power lines without polarity constraints.
It is rated for 3000 W peak pulse power under 10/1000 µs waveform, with full surge testing per production lot and 3σ screening on standby current (ID ≤ 5 µA at VWM). Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, eliminating dry-pack requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous operating voltage before conduction begins; sets minimum system voltage margin for reliable standby operation. |
| V(BR) min/max | 11.1–12.3 V - Breakdown occurs within this range at 1 mA; defines precise turn-on threshold for predictable clamping onset. |
| VC @ IPP | 17.0 V at 176.4 A - Clamping voltage during worst-case 10/1000 µs surge; determines protected circuit's maximum overvoltage exposure. |
| PPP | 3000 W - Peak pulse power handling capability; supports high-energy transients such as lightning-induced surges in industrial mains inputs. |
| TJ range | −55 to +150 °C - Wide junction temperature range enables deployment in uncontrolled environments like outdoor base stations or automotive engine bays. |
| ID @ VWM | ≤5 µA - Ultra-low leakage ensures minimal power loss and no thermal runaway risk in high-impedance bias networks. |
| Polarity | Bidirectional - Symmetric clamping behavior allows use on AC lines, differential buses, or floating grounds without orientation concerns. |
Pinout & Package
Package: Void-free transfer-molded thermosetting epoxy case (UL94V-0), 5 g weight, 21.03 × 6.86 × 8.64 mm (L × W × H) body dimensions. Pin 1 identified by dot marking; odd-numbered pins are cathodes per TVS element.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Channel 1 | Connected to protected line side; conducts surge current to ground when voltage exceeds V(BR) in either polarity. |
| Pin 2 | Anode of Channel 1 | Reference node (typically GND or return path); completes bidirectional conduction path with Pin 1. |
| Pin 3 | Cathode of Channel 2 | Dual-channel layout enables independent protection of two signal/power pairs on same footprint. |
| Pin 4 | Anode of Channel 2 | Second reference node; supports isolated or common-ground dual-line protection schemes. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping on AC or floating nodes without polarity-sensitive placement - reduces BOM count and layout complexity. |
| 3000 W 10/1000 µs rating | Meets IEC61000-4-5 Class 4 (42 Ω source) for secondary lightning immunity in industrial power entry designs. |
| RoHS-compliant e3 marking | Matte-tin plating meets lead-free soldering requirements and MIL-STD-750 Method 2026 solderability standards. |
| Lot-traceable high-reliability screening | Wafer and assembly lot traceability plus 3σ ID screening ensure consistent leakage performance across production batches. |
| Level 1 moisture sensitivity | No dry-pack or baking required prior to reflow - simplifies SMT manufacturing and reduces process overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | 600 W PPP rating, SMB package, 17.0 V VC @ 32.4 A IPP - lower energy handling than MADA3KP10CA. | Best suited for low-energy ESD/EFT only; insufficient for IEC61000-4-5 Class 3/4 lightning simulation. | Select SMBJ10CA only when space-constrained layouts and sub-1 kA surge requirements apply. |
| SMCJ10CA | 1500 W PPP rating, SMC package, 17.0 V VC @ 87.2 A IPP - half the energy capacity of MADA3KP10CA. | Valid for Class 1–2 lightning per 42 Ω source, but fails Class 4 derating curves above 85 °C ambient. | Choose SMCJ10CA for cost-sensitive industrial controls where full 3000 W rating is not mandated. |
Compared with SMBJ10CA and SMCJ10CA, the MADA3KP10CA delivers double the pulse power handling and extended high-temperature derating - enabling single-device compliance with IEC61000-4-5 Class 4 across full −55 to +150 °C operating range, whereas alternatives require parallel staging or thermal derating.

FAQ
What is the clamping voltage of MADA3KP10CA at its rated peak pulse current?
The MADA3KP10CA has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPP) of 176.4 A under 10/1000 µs waveform conditions. This value is guaranteed across the full operating temperature range and reflects worst-case device behavior during standardized surge testing - critical for verifying voltage margins in protected circuits. The MADA3KP10CA achieves this clamping performance while maintaining tight V(BR) tolerance (11.1–12.3 V).
Is MADA3KP10CA RoHS compliant and what does the 'e3' marking indicate?
Yes, MADA3KP10CA is RoHS compliant, as confirmed by the 'e3' suffix in its marking per Microsemi's nomenclature guide. The 'e3' designation specifies annealed matte-tin plating meeting JEDEC J-STD-020B Level 1 moisture sensitivity and MIL-STD-750 Method 2026 solderability requirements. This ensures compatibility with lead-free reflow processes without compromising long-term intermetallic stability - a verified characteristic of the MADA3KP10CA.
How does MADA3KP10CA differ from unidirectional variants like MDA3KP10A?
MADA3KP10CA is bidirectional, providing symmetrical clamping for both polarities, whereas MDA3KP10A is unidirectional and conducts only in reverse bias. The MADA3KP10CA supports AC-coupled lines, floating grounds, and differential buses without polarity constraints - unlike MDA3KP10A, which requires correct anode/cathode orientation. Both share identical VWM (10 V), V(BR), and VC ratings, but the MADA3KP10CA's bidirectional architecture doubles effective protection coverage per channel.
What IEC61000-4-5 Class levels does MADA3KP10CA support and under what source impedances?
MADA3KP10CA supports IEC61000-4-5 Class 1–4 with 42 Ω source impedance, Class 1–3 with 12 Ω, and Class 2 only with 2 Ω source impedance - as explicitly stated in the Microsemi datasheet. These classifications are validated through direct surge testing per test waveform parameters, not inferred. The MADA3KP10CA's 3000 W rating and thermal design enable sustained compliance across all specified classes without external derating beyond the published curve in Figure 3.
What is the maximum standoff voltage and leakage current specification for MADA3KP10CA?
The MADA3KP10CA has a rated reverse standoff voltage (VWM) of 10 V and a maximum standby current (ID) of 5 µA at that voltage and 25 °C. This ultra-low leakage ensures minimal power loss in high-impedance monitoring circuits and prevents thermal drift in precision bias networks. The MADA3KP10CA maintains this ID specification across its full −55 to +150 °C operating range, as confirmed by lot-screening data in the official datasheet.
