Product details
Overview
MDA3KP36AE3 from Microsemi is a unidirectional 3000 W surface-mount transient voltage suppressor (TVS) array with 36 V standoff voltage (VWM), 40.0–44.2 V breakdown voltage (V(BR)), and 58.1 V maximum clamping voltage (VC) at 51.6 A peak pulse current. It delivers secondary lightning protection per IEC61000-4-5 (42 Ω, Class 1–4) and ESD/EFT suppression per IEC61000-4-2/4-4 in telecom power interfaces.
For engineers reviewing the MDA3KP36AE3 datasheet, MDA3KP36AE3 pinout, MDA3KP36AE3 application, or MDA3KP36AE3 equivalent, key selection criteria include standoff voltage matching system DC rail, clamping margin relative to IC absolute maximum ratings, surge current capability under 10/1000 µs waveform, and RoHS-compliant lead-free termination for automated assembly.
Technical Context
The MDA3KP36AE3 operates as a unidirectional avalanche diode-based TVS, activated when reverse voltage exceeds its 40.0–44.2 V breakdown threshold. Its <100 ps response time enables sub-nanosecond clamping onset during fast transients like ESD.
It is rated for 3000 W peak pulse power at 10/1000 µs, with thermal derating above 25 °C per Figure 3. The device features void-free UL94V-0 epoxy packaging, tin-plated terminals compliant with MIL-STD-750 Method 2026, and polarity defined by odd-numbered pins as cathodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before conduction begins; must exceed system's peak DC rail voltage. |
| V(BR) min–max | 40.0–44.2 V @ 1 mA - Confirmed avalanche onset range; ensures predictable turn-on across temperature and lot variation. |
| VC @ IPP | 58.1 V @ 51.6 A - Clamped voltage during full 10/1000 µs surge; defines worst-case overvoltage seen by downstream circuitry. |
| IPP | 51.6 A - Peak current survivable at rated clamping voltage; correlates directly to IEC61000-4-5 Class 4 (42 Ω source) immunity. |
| ID @ VWM | 2 µA max - Standby leakage at 36 V; negligible power loss in high-impedance monitoring or low-power standby paths. |
| TJ/TSTG | −55 to +150 °C - Extended industrial temperature range supports deployment in base station power supplies and outdoor equipment enclosures. |
Pinout & Package
MDA3KP36AE3 uses a 3-pin SMC (DO-214AB) surface-mount package with void-free UL94V-0 epoxy body, tin-plated terminations, and polarity marked by a dot indicating Pin 1 (cathode). Odd-numbered pins are cathodes per device configuration.
| 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 | Common anode tie point; routed to system ground plane for low-inductance return path. |
| Pin 3 | Cathode | Second cathode terminal; enables dual-line protection (e.g., differential signal pair or redundant power rails) using single device. |
Key Features
| Feature | Design Value |
|---|---|
| 3000 W peak pulse power | Enables compliance with IEC61000-4-5 Class 4 (42 Ω) without external series impedance or cascaded stages. |
| RoHS-compliant e3 termination | Lead-free matte-tin plating meets J-STD-020B Level 1 moisture sensitivity and reflow compatibility up to 260 °C. |
| Unidirectional construction | Prevents forward conduction during normal operation while providing robust reverse surge clamping on positive transients. |
| 100% surge tested | Each unit validated at full 3000 W rating ensures field reliability in mission-critical telecom and industrial power systems. |

Use Value: UL94V-0 epoxy housing and −55 to +150 °C rating ensure long-term stability in thermally constrained medical enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | 600 W rating, 58.1 V VC @ 10.3 A IPP - lower surge capacity than MDA3KP36AE3's 3000 W/51.6 A. | Suitable for consumer-grade ESD-only protection; insufficient for IEC61000-4-5 Class 3+ or lightning-induced surges. | Select SMBJ36A only when cost and board space constrain design and surge threat level is limited to ESD/EFT. |
| SMCJ36A | 1500 W rating, 58.1 V VC @ 25.8 A IPP - half the peak power and current capability of MDA3KP36AE3. | Valid for IEC61000-4-5 Class 2 (42 Ω) but not Class 4; requires parallel devices for equivalent energy handling. | Choose SMCJ36A if legacy layout uses SMC footprint and surge requirements are moderate; verify thermal margin under repeated pulses. |
Compared with SMBJ36A and SMCJ36A, the MDA3KP36AE3 delivers 2× and 2× higher peak pulse power respectively, enabling single-device Class 4 lightning protection without layout redesign or paralleling-critical for space-constrained telecom and industrial power modules.

FAQ
What is the clamping voltage of MDA3KP36AE3 at its rated peak pulse current?
The MDA3KP36AE3 has a maximum clamping voltage (VC) of 58.1 V at 51.6 A peak pulse current (IPP) under 10/1000 µs waveform conditions. This value is measured per standard test methods and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. Designers must ensure downstream components have absolute maximum voltage ratings exceeding 58.1 V to prevent damage. The MDA3KP36AE3 achieves this clamping performance while maintaining sub-100 ps response time.
Is MDA3KP36AE3 RoHS-compliant and lead-free?
Yes, MDA3KP36AE3 is RoHS-compliant and carries the "e3" suffix indicating matte-tin plating per J-STD-020B Level 1 moisture sensitivity. Its termination withstands 260 °C soldering for 10 seconds and requires no dry pack storage. The device meets IPC/JEDEC standards for lead-free assembly and is qualified for high-reliability reflow profiles used in telecom and industrial manufacturing. MDA3KP36AE3's RoHS compliance is documented in Microsemi's official product change notices and material declarations.
How does MDA3KP36AE3 differ from bidirectional variants like MDA3KP36CE3?
MDA3KP36AE3 is unidirectional and protects against positive transients only, with Pin 1 and Pin 3 as cathodes referenced to common anode (Pin 2). In contrast, MDA3KP36CE3 is bidirectional and clamps both polarities, making it suitable for AC lines or differential data buses. The unidirectional MDA3KP36AE3 offers lower leakage (<2 µA) and tighter V(BR) tolerance (±5%) versus bidirectional versions, which trade off some precision for symmetrical clamping. System topology determines selection: use MDA3KP36AE3 for DC power rails where polarity is fixed.
What is the standoff voltage rating of MDA3KP36AE3 and how should it be applied in circuit design?
The MDA3KP36AE3 has a rated working standoff voltage (VWM) of 36 V, meaning it remains non-conductive up to this DC or peak AC voltage across its terminals. Designers must select VWM ≥ 1.1× the system's maximum continuous operating voltage to avoid leakage or thermal runaway. For a nominal 30 V DC rail, MDA3KP36AE3 provides 20% margin. Exceeding VWM risks premature conduction; undersizing VWM reduces clamping margin. MDA3KP36AE3's 36 V VWM is optimized for 24–48 V industrial and telecom power domains.
Does MDA3KP36AE3 require derating at elevated ambient temperatures?
Yes, MDA3KP36AE3 requires thermal derating above 25 °C ambient, as shown in Figure 3 of its datasheet. At 85 °C, its peak pulse power drops to ~75% of the 3000 W rating, reducing effective IPP to approximately 38.7 A. This derating is critical for enclosed or high-power-density applications such as base station power supplies. Designers must consult the published derating curve and validate clamping performance under worst-case thermal conditions. MDA3KP36AE3's −55 to +150 °C junction range supports operation, but sustained high-temperature surge duty demands careful thermal layout and margining.
