Product details
Overview
MDA3KP6.5CAE3 from Microsemi is a bidirectional 3000 W transient voltage suppressor (TVS) array in a surface-mount DO-214AB package, designed for high-reliability secondary lightning and ESD protection. It features a 6.5 V standoff voltage (VWM), 7.22–7.98 V breakdown range (V(BR)), 11.2 V maximum clamping voltage at 267.9 A peak pulse current, and operates from −55 °C to +150 °C.
For engineers reviewing the MDA3KP6.5CAE3 datasheet, MDA3KP6.5CAE3 pinout, MDA3KP6.5CAE3 application, or MDA3KP6.5CAE3 equivalent, key selection criteria include bidirectional polarity, IEC61000-4-2/4-4/4-5 compliance, 10/1000 µs surge rating, RoHS-compliant matte-tin plating, and MIL-PRF-19500 upscreening capability.
Technical Context
The MDA3KP6.5CAE3 is a silicon avalanche diode-based TVS array with symmetrical bidirectional clamping behavior, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its sub-5 ns response time and <100 ps junction delay ensure effective suppression of ESD, EFT, and switching transients before sensitive circuitry is damaged.
It delivers 3000 W peak pulse power at 10/1000 µs waveform with 11.2 V clamping voltage at 267.9 A IPP, and supports derating to 50% power at +125 °C per Figure 3. Standby leakage is ≤500 µA at 6.5 V VWM, and it meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous operating voltage before clamping begins; matches 5 V logic rails with margin. |
| V(BR) min/max | 7.22–7.98 V - Confirmed avalanche onset range at 10 mA test current; ensures predictable turn-on. |
| VC @ IPP | 11.2 V at 267.9 A - Clamping voltage under full 10/1000 µs surge; limits downstream voltage stress. |
| PPP | 3000 W - Peak pulse power handling at 10/1000 µs; enables Class 3/4 IEC61000-4-5 protection. |
| TJ/TSTG | −55 °C to +150 °C - Extended thermal range supports automotive under-hood and industrial control environments. |
| ID @ VWM | ≤500 µA - Low standby leakage preserves battery life and avoids false triggering in low-power circuits. |
| RoHS | e3 - Matte-tin termination compliant with EU RoHS Directive 2011/65/EU; no lead or hazardous substances. |
Pinout & Package
MDA3KP6.5CAE3 uses a DO-214AB (SMC) surface-mount package: void-free UL94V-0 epoxy body, 5 g weight, and tin-lead or annealed matte-tin terminations solderable per MIL-STD-750 Method 2026. Pin 1 is marked by a dot on top; odd-numbered pins are cathodes per device polarity convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode (Channel 1) | Primary current sink during positive transients on anode-to-cathode path; defines polarity reference. |
| Pin 2 | Anode (Channel 1) | Input node for protected line; bidirectional symmetry means same terminal serves both polarities. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional construction | Enables symmetric clamping on AC or differential signals without external polarity management. |
| MIL-PRF-19500 screening option | Supports high-reliability aerospace/defense programs via wafer lot traceability and 3σ ID screening. |
| 10/1000 µs 3000 W surge rating | Validated for IEC61000-4-5 Class 3 (12 Ω source) and Class 4 (2 Ω source) secondary lightning events. |
| Level 1 moisture sensitivity | No dry pack or baking required prior to reflow; compatible with standard SMT assembly processes. |
| Sub-5 ns response time | Clamps ESD transients (IEC61000-4-2 ±8 kV contact) before IC damage thresholds are exceeded. |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |
|---|---|
Use Scenario: Protection of CAN FD and LIN bus lines against load dump and alternator ripple-induced surges. IC Role / Device Role / Timing Role: Bidirectional TVS array placed at connector interface to clamp common-mode transients before transceiver input. Use Value: Maintains signal integrity with 11.2 V clamping at 267.9 A while surviving repeated 12 V system-level surges per ISO 7637-2. | Use Scenario: Guarding microcontroller GPIOs and sensor inputs against ESD during assembly and field service. IC Role / Device Role / Timing Role: Primary ESD shunt at board edge, diverting ±8 kV contact discharge per IEC61000-4-2 away from MCU pins. Use Value: Sub-5 ns response prevents latch-up or gate oxide damage; 500 µA leakage avoids interference with 12-bit ADC references. |
| Telecom Power Feeds | Medical Imaging Interfaces |
Use Scenario: Safeguarding PoE-powered Ethernet PHYs from induced RF and lightning-induced surges on twisted-pair cables. IC Role / Device Role / Timing Role: Common-mode TVS across differential pairs, referenced to chassis ground to suppress asymmetrical transients. Use Value: 3000 W 10/1000 µs rating handles worst-case IEC61000-4-5 coupling; bidirectional symmetry eliminates polarity routing errors. | Use Scenario: Shielding ultrasound transducer analog front-end from EFT bursts during probe cable movement. IC Role / Device Role / Timing Role: Low-capacitance TVS at ADC input stage to prevent saturation and data corruption during fast transients. Use Value: 11.2 V clamping ensures amplifier output stays within rail-to-rail range; 7.22–7.98 V V(BR) avoids false triggering during 5 V supply ripple. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5CA | 600 W PPP rating (vs. 3000 W); same VWM and bidirectional polarity; DO-214AA package. | Limited to lower-energy threats (e.g., IEC61000-4-2 only); unsuitable for IEC61000-4-5 Class 3/4. | Select when space constraints prohibit DO-214AB and surge energy is below 600 W. |
| SMCJ6.5CA | 1500 W PPP rating; identical VWM, V(BR), and DO-214AB package; higher VC (11.5 V). | Meets IEC61000-4-5 Class 2 (2 Ω source) but not Class 3/4; lower cost for mid-tier protection. | Choose when 1500 W suffices and budget is constrained; verify clamping margin with downstream IC abs max ratings. |
Compared with MDA3KP6.5CAE3, SMBJ6.5CA offers smaller footprint but sacrifices 80% surge capacity, while SMCJ6.5CA retains the same package and polarity but halves the peak power-making MDA3KP6.5CAE3 the only option for full 3000 W, Class 4-compliant protection in this voltage class.

FAQ
What does the 'C' suffix in MDA3KP6.5CAE3 indicate?
The 'C' suffix in MDA3KP6.5CAE3 denotes bidirectional polarity, meaning the device provides symmetrical clamping for both positive and negative transients across its terminals. This eliminates the need for polarity-aware layout and makes it ideal for protecting AC-coupled interfaces like CAN, RS-485, or Ethernet pairs. Unlike unidirectional variants (e.g., MDA3KP6.5AE3), MDA3KP6.5CAE3 has no anode/cathode distinction in normal operation.
Is MDA3KP6.5CAE3 suitable for IEC61000-4-5 Class 4 lightning protection?
Yes, MDA3KP6.5CAE3 is explicitly rated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 2 Ω source impedance, as confirmed in the Applications/Benefits section of the RF01243 datasheet. Its 3000 W peak pulse power and 11.2 V clamping voltage at 267.9 A enable reliable energy diversion without exceeding downstream IC absolute maximum ratings under worst-case coupling conditions.
What is the maximum allowable junction temperature for MDA3KP6.5CAE3 during surge events?
The maximum junction temperature for MDA3KP6.5CAE3 is +150 °C, as specified in the Absolute Maximum Ratings table. During repetitive 10/1000 µs surges, thermal derating must be applied per Figure 3: at +125 °C ambient, peak pulse power drops to 50% of the 25 °C rating (i.e., 1500 W). The device's 5 g mass and DO-214AB thermal path support brief high-power dissipation without exceeding TJ(max) if duty cycle remains ≤0.05%.
Does MDA3KP6.5CAE3 require special handling for moisture sensitivity?
No, MDA3KP6.5CAE3 is rated IPC/JEDEC J-STD-020B Level 1, meaning it has unlimited floor life at ≤30 °C/60% RH and requires no dry pack or baking prior to reflow soldering. This simplifies manufacturing integration and reduces process risk compared to higher MSL-rated components, while maintaining robust surge performance after standard SMT assembly.
How does the e3 marking on MDA3KP6.5CAE3 relate to RoHS compliance?
Per the part nomenclature on page 2 of RF01243 Rev B, the 'e3' suffix on MDA3KP6.5CAE3 confirms full compliance with the EU RoHS Directive 2011/65/EU, indicating annealed matte-tin plating with no lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE. This ensures environmental safety and regulatory acceptance for global commercial and industrial deployments without compromising solderability or surge reliability.
