Product details
Overview
MPLAD36KP260A/TR from Microsemi is a surface-mount, bidirectional transient voltage suppressor (TVS) rated for 36,000 W peak pulse power at 10/1000 μs, with 260 V working standoff voltage (VWM), 289–320 V breakdown voltage (VBR), and 419 V clamping voltage (VC) at 86 A peak impulse current. It delivers lightning and load dump protection in aerospace avionics meeting RTCA DO-160 Section 22.
For engineers reviewing the MPLAD36KP260A/TR datasheet, MPLAD36KP260A/TR pinout, MPLAD36KP260A/TR application, or MPLAD36KP260A/TR equivalent, key selection criteria include verified IEC 61000-4-5 Class 3/4 secondary lightning protection at 2 Ω and 12 Ω source impedances, AEC-Q101 qualification, and low thermal resistance (RθJC = 1.0 °C/W) enabling high-reliability mounting on FR4 with 1 oz Cu.
Technical Context
This TVS diode operates in bidirectional avalanche mode to clamp transients across both polarities, with sub-5 ns response time and <10 µA standby current at 260 V. Its PLAD package features a metal base acting as cathode terminal, optimized for low junction-to-case thermal resistance to sustain multi-stroke surge events.
It meets RTCA DO-160G Waveform 4 (6.4/69 μs) Level 4/5 pin injection requirements and supports IEC 61000-4-2 ESD (±30 kV contact) and IEC 61000-4-4 EFT (4 kV) immunity when used with proper PCB layout and grounding per Figure 7 pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 260 V DC - maximum continuous operating voltage before conduction begins; matches 220–240 VAC-derived rail systems. |
| VBR @ IBR=5 mA | 289–320 V - guaranteed breakdown range ensures reliable turn-on margin above VWM without premature leakage. |
| VC @ IPP=86 A | 419 V - clamping voltage limits downstream component stress during 10/1000 μs surges; 61% overvoltage headroom vs. VWM. |
| RθJC | 1.0 °C/W - enables direct heatsink mounting to dissipate 36 kW pulses without thermal runaway under specified duty cycle. |
| ID @ VWM | <10 µA - ultra-low leakage preserves signal integrity and battery life in always-on 260 V monitoring circuits. |
| PPP @ 10/1000 μs | 36,000 W - peak power rating validated per MIL-STD-883 Method 3015.8; supports multi-stroke DO-160 Section 22 compliance. |
