Product details
Overview
MADA3KP6.5AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 6.5 V standoff voltage (VWM), 7.22–7.98 V breakdown voltage (V(BR)), and 11.2 V clamping voltage (VC) at 267.9 A peak pulse current, used for ESD/EFT/IEC61000-4-2/4-4 protection and secondary lightning surge suppression in telecom power interfaces.
For engineers reviewing the MADA3KP6.5AE3 datasheet, MADA3KP6.5AE3 pinout, MADA3KP6.5AE3 application, or MADA3KP6.5AE3 equivalent, this page delivers verified electrical parameters, package dimensions, IEC61000-4-5 class compliance per source impedance, RoHS-compliant e3 marking, and real-world TVS selection criteria including VWM ≥ system peak operating voltage and VC < protected IC's absolute maximum rating.
Technical Context
The MADA3KP6.5AE3 operates as a unidirectional avalanche diode-based TVS, responding in <100 ps to transients and clamping at 11.2 V under 267.9 A (10/1000 µs waveform). It meets IEC61000-4-5 Class 1–4 for 42 Ω source impedance and Class 1–3 for 12 Ω, with full surge testing per unit and 3σ lot screening on standby current (ID ≤ 500 µA).
Its thermoset epoxy case complies with UL94V-0, terminals use annealed matte-tin plating per MIL-STD-750 Method 2026, and polarity follows odd-pin cathode convention. The device is rated for -55 °C to +150 °C junction temperature and requires no dry pack (Moisture Sensitivity Level 1 per J-STD-020B).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous reverse working voltage before conduction; must exceed circuit's peak operating voltage. |
| V(BR) min/max | 7.22–7.98 V @ 10 mA - Breakdown threshold range defining turn-on consistency across production lots. |
| VC @ IPP | 11.2 V @ 267.9 A - Clamped voltage during worst-case 10/1000 µs surge; determines stress on downstream ICs. |
| PPP | 3000 W @ 10/1000 µs - Peak pulse power handling capacity; defines survivability against lightning-induced surges. |
| ID @ VWM | ≤500 µA - Standby leakage current at rated standoff; impacts low-power system quiescent current budget. |
| TJ/TSTG | -55 to +150 °C - Operating and storage temperature range; supports industrial and automotive under-hood environments. |
| RoHS | e3 marking - Lead-free, RoHS-compliant termination; satisfies EU Directive 2011/65/EU requirements. |
Pinout & Package
Package: Surface-mount DO-214AB (SMC) molded thermosetting epoxy case, UL94V-0 rated, ~5 g weight, moisture sensitivity level 1 (no dry pack required).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A | 600 W PPP rating (vs. 3000 W); same VWM/V(BR)/VC but lower IPP (102.7 A vs. 267.9 A). | Not suitable for IEC61000-4-5 Class 3/4 or high-energy inductive switching; limited to ESD/EFT-only zones. | Select SMAJ6.5A only for space-constrained PCBs where surge energy is confirmed ≤600 W. |
| 1.5KE6.8A | Through-hole DO-201 package; 1500 W PPP; higher clamping (11.5 V) and leakage (1000 µA); no e3 RoHS marking. | Requires rework for SMT assembly; unsuitable for automated high-volume production or RoHS-mandated medical/aerospace designs. | Choose 1.5KE6.8A only for legacy through-hole systems with existing tooling and no RoHS requirement. |
Compared with SMAJ6.5A and 1.5KE6.8A, the MADA3KP6.5AE3 delivers 5× higher surge power handling, SMT manufacturability, guaranteed RoHS compliance, and tighter leakage control-making it the preferred choice for new industrial, telecom, and automotive designs demanding robust, production-ready TVS protection.

FAQ
What is the clamping voltage of the MADA3KP6.5AE3 and how is it measured?
The MADA3KP6.5AE3 has a maximum clamping voltage (VC) of 11.2 V, measured at its peak pulse current (IPP) of 267.9 A under standardized 10/1000 µs waveform conditions. This value represents the upper limit of voltage seen by protected circuitry during worst-case surge events and is validated per Figure 2 in the official RF01243 datasheet. Designers must ensure this VC remains below the absolute maximum rating of downstream ICs.
Is the MADA3KP6.5AE3 RoHS compliant and what does the 'e3' suffix indicate?
Yes, the MADA3KP6.5AE3 is RoHS compliant, as confirmed by the 'e3' suffix in its part number per Microsemi's nomenclature guide. The 'e3' designation specifies annealed matte-tin plating meeting EU Directive 2011/65/EU requirements, with no lead content exceeding 0.1% by weight in homogeneous materials. This enables use in medical, consumer, and industrial products sold in regulated markets.
Can the MADA3KP6.5AE3 be used for bidirectional transient protection?
No, the MADA3KP6.5AE3 is unidirectional only, as indicated by the absence of a 'C' suffix (e.g., MADA3KP6.5CE3 would be bidirectional). Its polarity is fixed: Pin 1 is cathode, Pin 2 is anode. For AC-coupled or dual-polarity signal lines, a bidirectional variant or back-to-back diode configuration is required-using MADA3KP6.5AE3 in reverse-biased mode risks permanent damage.
What IEC61000-4-5 protection classes does the MADA3KP6.5AE3 support?
The MADA3KP6.5AE3 supports IEC61000-4-5 Class 1–4 with 42 Ω source impedance, Class 1–3 with 12 Ω, and Class 2 with 2 Ω source impedance, as explicitly listed in the Applications/Benefits section of RF01243 Rev B. These classifications reflect tested performance against secondary lightning surges, not theoretical capability-actual implementation requires proper PCB layout, grounding, and series impedance matching.
How does the MADA3KP6.5AE3 compare to standard SMAJ-series TVS diodes in surge handling?
The MADA3KP6.5AE3 provides 3000 W peak pulse power, five times higher than the 600 W rating of SMAJ6.5A. This enables reliable protection against high-energy threats like IEC61000-4-5 Class 4 surges and automotive load dump, whereas SMAJ6.5A is limited to ESD/EFT-level events. Both share identical VWM and VC, but MADA3KP6.5AE3's higher IPP (267.9 A vs. 102.7 A) reflects its superior energy absorption capacity.
