Product details
Overview
PMEG100T20ELXD-QX from Nexperia is a 100 V, 2 A trench Schottky barrier rectifier in CFP2-HP (SOD323HP) package, designed for high-efficiency DC-to-DC conversion and automotive LED lighting. It delivers low forward voltage (810–880 mV at 2 A, 25 °C), ultra-low reverse leakage (0.12 µA at 100 V, 25 °C), and qualified AEC-Q101 reliability for under-hood applications.
For engineers reviewing the PMEG100T20ELXD-QX datasheet, PMEG100T20ELXD-QX pinout, PMEG100T20ELXD-QX application, or PMEG100T20ELXD-QX equivalent, key selection criteria include thermal resistance to solder point (6 K/W), reverse recovery charge (1.2 nC), junction temperature rating (175 °C), and clip-bonded power flat lead construction for automotive-grade thermal performance.
Technical Context
This device uses trench Schottky architecture to achieve lower VF and Qrr versus planar Schottky diodes, enabling higher switching efficiency in SMPS and OR-ing circuits. Its clip-bonding technology directly connects the die to the exposed cathode heatsink tab, reducing Rth(j-sp) to 6 K/W.
The CFP2-HP package integrates a thermally optimized copper leadframe with solderable ends and an exposed cathode pad, supporting high-current handling (IF(AV) = 2 A, Tsp ≤ 167 °C) while maintaining compact 2.2 mm × 1.3 mm footprint. Reverse breakdown voltage is rated at 100 V with tight distribution (min 100 V at IR = 1 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 100 V reverse voltage rating - supports 48 V automotive bus derating and 36 V nominal input SMPS designs |
| IF(AV) | 2 A average forward current - sustained at δ = 0.5, 20 kHz square wave with solder point ≤167 °C |
| VF | 810–880 mV at IF = 2 A, Tj = 25 °C - enables <1.8 W conduction loss in 12 V → 5 V buck converters |
| IR | 0.12–0.6 µA at VR = 100 V, Tj = 25 °C - minimizes standby power loss in reverse polarity protection |
| Qrr | 1.2 nC - reduces switching loss and EMI in high-frequency freewheeling and OR-ing applications |
| Rth(j-sp) | 6 K/W - enables direct thermal coupling to PCB copper pour for high-power density layouts |
| Tj(max) | 175 °C - meets AEC-Q101 transient thermal stress requirements for automotive under-hood use |
Pinout & Package
Encapsulated in CFP2-HP (SOD323HP): 2.2 mm × 1.3 mm × 0.68 mm surface-mount plastic package with exposed cathode heatsink tab and solderable lead ends.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main heat path terminal - connected to exposed copper tab for low Rth(j-sp) = 6 K/W |
| 2 | Anode (A) | Current entry point - bonded via clip to die anode region; optimized for low-inductance layout |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 810 mV typ. at 2 A ensures <1.6 W conduction loss in 12 V → 3.3 V point-of-load converters |
| Clip-bonded construction | Direct die-to-tab thermal path achieves Rth(j-sp) = 6 K/W - 4× better than standard SOD323 |
| AEC-Q101 qualification | Validated for automotive temperature cycling, HTRB, and ESD per AEC-Q101 Rev G - suitable for engine control modules |
| Low Qrr and IRM | 1.2 nC Qrr and 0.285 A IRM reduce turn-off overshoot and snubber losses in 500 kHz+ SMPS |
| Exposed heatsink tab | Enables >1 cm² copper pour attachment on PCB - critical for sustaining 2 A continuous in ambient >85 °C |
Applications
| Automotive LED Headlamp Driver | 48 V Automotive DC-DC Converter |
|---|---|
Use Scenario: High-side switch protection and freewheeling path in constant-current LED driver ICs powering adaptive front lighting systems. IC Role / Device Role / Timing Role: Freewheeling diode during MOSFET off-time; handles 2 A peak inductive kickback at 200 kHz switching. Use Value: Low VF and Qrr minimize thermal rise in confined headlamp housing; AEC-Q101 rating ensures 15-year lifetime at 125 °C junction. |
Use Scenario: Output rectification in synchronous-buck-derived 48 V → 12 V intermediate bus converter for ADAS domain controllers. IC Role / Device Role / Timing Role: Secondary-side Schottky rectifier replacing synchronous FET in cost-sensitive designs requiring <100 ns recovery. Use Value: 100 V VR rating provides 2× margin over 48 V bus transients; 6 K/W Rth(j-sp) enables 2 A operation without heatsink on 2-layer PCB. |
| Industrial OR-ing Controller | Reverse Polarity Protection Circuit |
Use Scenario: Diode-OR configuration in redundant 24 V power supplies for PLC backplanes, preventing backfeed between rails. IC Role / Device Role / Timing Role: Unidirectional current valve - conducts only when forward biased; blocks reverse current during supply fault. Use Value: 0.12 µA IR at 25 °C eliminates measurable standby drain; low VF avoids voltage droop across dual-rail paths. |
Use Scenario: Input protection for 12 V embedded controllers in fleet telematics units exposed to battery jump-start reversals. IC Role / Device Role / Timing Role: Series blocking diode - placed between connector and LDO input to prevent damage during -12 V misconnection. Use Value: 100 V VR withstands ±30 V transients; 175 °C Tj rating survives 150 °C ambient under sealed enclosure conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY10-M3/54 | Same 100 V/2 A rating but SOD-123FL package; Rth(j-a) = 190 K/W vs 230 K/W; no clip bonding | Lacks AEC-Q101 qualification; higher VF (870 mV min) and Qrr (2.5 nC) | Acceptable for non-automotive industrial SMPS where thermal margin is >20 °C |
| ON Semiconductor NSR20F100MX | CFP3 package (larger 2.9 mm × 1.9 mm); Rth(j-sp) = 5.5 K/W; VF = 790 mV typ. at 2 A | Higher IFSM (50 A vs 33 A); same AEC-Q101 grade but different marking and tape/reel packaging | Preferred when board space allows larger footprint and higher surge immunity is required |
Compared with PMEG100T20ELXD-QX, the VS-2EY10-M3/54 trades automotive qualification and thermal performance for lower cost, while the NSR20F100MX offers marginally better thermal and surge specs in a larger footprint - making PMEG100T20ELXD-QX optimal for space-constrained AEC-Q101 designs needing minimal Rth(j-sp).

FAQ
What is the maximum allowable solder point temperature for continuous operation?
The datasheet specifies IF(AV) = 2 A is guaranteed at Tsp ≤ 167 °C under δ = 0.5, 20 kHz square wave conditions. Exceeding 167 °C reduces average current capability per Fig. 10; sustained operation above 175 °C risks irreversible degradation due to junction temperature limits.
Does PMEG100T20ELXD-QX support reflow soldering per JEDEC J-STD-020?
Yes - the CFP2-HP package is qualified for lead-free reflow per JEDEC J-STD-020D. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s before and after peak. Figure 19 provides recommended stencil and land pattern dimensions.
How does its reverse recovery behavior differ from conventional silicon diodes?
As a Schottky device, it exhibits majority-carrier conduction with no minority-carrier storage - resulting in trr < 3 ns (step recovery) and zero reverse recovery tail. This eliminates switching loss spikes and EMI associated with PN diode recovery, confirmed by test definitions in Fig. 14–15.
Can this diode replace a standard SOD-323 Schottky in existing layouts?
No - CFP2-HP (SOD323HP) has identical outline dimensions but features an exposed cathode tab requiring a dedicated 1 cm² copper pad per Fig. 19. Standard SOD-323 footprints lack thermal relief and solder mask openings for the heatsink tab, risking insufficient thermal transfer and premature failure.
