Product details
Overview
MADA3KP33CAE3 from Microsemi is a bidirectional 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 provides secondary lightning protection per IEC61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD/EFT suppression per IEC61000-4-2/4-4, and inductive switching transient protection in telecom power interfaces.
For engineers reviewing the MADA3KP33CAE3 datasheet, MADA3KP33CAE3 pinout, MADA3KP33CAE3 application, or MADA3KP33CAE3 equivalent, key selection criteria include bidirectional polarity, RoHS-compliant matte-tin plating, 10/1000 µs surge rating, junction temperature range (−55 to +150 °C), and IEC61000-4-5 Class 1–4 compliance with defined source impedances.
Technical Context
The MADA3KP33CAE3 operates as a high-reliability, vertically mounted TVS array designed for fast-clamping protection of DC power rails and signal lines against high-energy transients. Its bidirectional construction enables symmetrical clamping for AC-coupled or floating systems, and its <5 ns response time ensures effective suppression of ESD (IEC61000-4-2), EFT (IEC61000-4-4), and lightning-induced surges (IEC61000-4-5).
It is rated for 3000 W peak pulse power at 10/1000 µs waveform, with clamping voltage tightly specified at 53.3 V (max) under 56.2 A IPP, and exhibits ≤2 µA standby current at 33 V VWM. The device undergoes full lot surge testing and supports MIL-PRF-19500 upscreening options for high-reliability programs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | 600 W PPP rating, same 33 V VWM and bidirectional polarity, but smaller SMB package (3.5 mm × 4.6 mm) | Limited to Class 2/3 IEC61000-4-5 (42 Ω); insufficient for Class 4 lightning events requiring 3000 W | Select when space-constrained and surge energy is ≤600 W; not suitable for telecom central office or outdoor infrastructure. |
| SMCJ33CA | 1500 W PPP rating, identical VWM/V(BR)/VC specs, DO-214AB package (7.1 mm × 6.2 mm) | Meets IEC61000-4-5 Class 3 (42 Ω), but fails Class 4 marginally due to lower energy absorption | Valid for industrial control cabinets with moderate surge exposure; verify layout thermal relief for 1500 W dissipation. |
Compared with SMBJ33CA and SMCJ33CA, the MADA3KP33CAE3 delivers double the surge energy capacity of SMCJ33CA and five times that of SMBJ33CA-enabling single-device compliance with IEC61000-4-5 Class 4 across all source impedances (2 Ω, 12 Ω, 42 Ω), critical for telecom and utility-grade equipment.

FAQ
What is the clamping voltage of MADA3KP33CAE3 under maximum surge conditions?
The MADA3KP33CAE3 has a maximum clamping voltage (VC) of 53.3 V at 56.2 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The MADA3KP33CAE3 maintains this clamping performance without degradation after multiple surge events, provided thermal limits are observed.
Is MADA3KP33CAE3 suitable for IEC61000-4-5 Class 4 lightning surge testing?
Yes, the MADA3KP33CAE3 is explicitly rated for IEC61000-4-5 Class 4 with 42 Ω, 12 Ω, and 2 Ω source impedances per the manufacturer's application guidance. Its 3000 W peak pulse power rating and verified clamping behavior at 56.2 A IPP ensure compliance when installed with appropriate PCB layout (short traces, low-inductance grounding). The MADA3KP33CAE3 meets Class 4 requirements where other 33 V TVS devices like SMCJ33CA fall short.
What does the "C" and "E3" suffix mean in MADA3KP33CAE3?
In MADA3KP33CAE3, "C" denotes bidirectional polarity, enabling symmetrical clamping for AC or floating systems, while "E3" indicates RoHS-compliant matte-tin plating per JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. These suffixes are integral to the part identity: removing "C" yields a unidirectional variant (MADA3KP33AE3), and omitting "E3" implies non-RoHS tin-lead plating. The MADA3KP33CAE3 must be ordered with both suffixes to obtain the specified bidirectional, lead-free configuration.
How does MADA3KP33CAE3 compare to unidirectional TVS devices in power rail protection?
The MADA3KP33CAE3 provides bidirectional clamping, making it ideal for protecting AC-coupled lines, differential buses (e.g., RS-485), or systems with undefined polarity-unlike unidirectional TVS diodes that only clamp positive transients relative to ground. Its symmetrical V-I curve ensures equal protection against both positive and negative excursions, eliminating the need for dual unidirectional devices. For pure DC rails referenced to ground, a unidirectional part may offer slightly lower leakage, but the MADA3KP33CAE3 remains fully functional and simplifies design validation.
Can MADA3KP33CAE3 be used in parallel to increase surge current handling?
No-MADA3KP33CAE3 is not designed for parallel operation due to inherent parameter mismatches (e.g., V(BR) tolerance of ±5 %) that cause current imbalance and premature failure of one device. Surge current sharing requires active balancing or matched arrays; the MADA3KP33CAE3 datasheet specifies absolute maximum ratings assuming single-device use. For higher energy requirements, select a higher-rated part (e.g., MADA3KP40CAE3) or implement staged protection with upstream current-limiting impedance.
