Product details
Overview
PMEG2005CT-QR from Nexperia is a dual common-cathode Schottky barrier rectifier in SOT23 package, designed for low-voltage, high-efficiency rectification and reverse polarity protection. It delivers 500 mA average forward current per diode, 20 V reverse voltage rating, 360–390 mV forward voltage at 0.5 A, and 22 ns reverse recovery time - enabling use in automotive-grade DC-DC converters and compact power rails.
For engineers reviewing the PMEG2005CT-QR datasheet, PMEG2005CT-QR pinout, PMEG2005CT-QR application, or PMEG2005CT-QR equivalent, key selection criteria include its AEC-Q101 qualification, low VF performance at 0.5 A, thermal resistance of 270–375 K/W (junction-to-ambient), and dual-diode common-cathode configuration for space-constrained bidirectional protection.
Technical Context
This device integrates two planar Schottky diodes sharing a common cathode terminal in a single SOT23 package, with an integrated guard ring for mechanical and electrical stress protection. Its architecture eliminates minority-carrier storage, enabling ultrafast switching (trr = 22 ns) and near-zero reverse recovery loss - critical for high-frequency SMPS topologies.
Rated for 150 °C junction temperature and qualified to AEC-Q101, it supports operation across −55 °C to +150 °C ambient, with thermal performance dependent on PCB mounting: 270 K/W on ceramic (Al₂O₃), 310 K/W on FR4 with extended cathode pad, and 375 K/W on standard FR4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - defines maximum blocking capability in reverse-biased applications like reverse polarity protection. |
| Avg. Forward Current (IF(AV)) | 0.5 A per diode - sustainable continuous DC or pulsed current under specified thermal conditions (e.g., δ = 0.5, Tsp ≤ 130 °C). |
| Forward Voltage (VF) | 360–390 mV at IF = 0.5 A, Tj = 25 °C - enables <0.2 W conduction loss per diode at full rated current, improving system efficiency. |
| Reverse Recovery Time (trr) | 22 ns - ensures minimal switching loss and EMI in >1 MHz DC-DC converters and synchronous rectifier auxiliary paths. |
| Reverse Leakage (IR) | 30–200 µA at VR = 20 V, Tj = 25 °C - low leakage preserves battery life in always-on automotive modules. |
| Diode Capacitance (Cd) | 66–80 pF at VR = 1 V, f = 1 MHz - limits high-frequency AC coupling and noise injection in signal-path protection circuits. |
| Junction Temperature (Tj) | 150 °C max - supports reliable operation in under-hood automotive environments without derating at moderate power levels. |
Pinout & Package
Encapsulated in a standard SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch), the PMEG2005CT-QR uses a 3-terminal common-cathode configuration optimized for board space reduction and thermal management via cathode pad soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input/positive-side connection for first Schottky diode; used for unidirectional current path or OR-ing function. |
| 2 | Anode (Diode 2) | Independent input/positive-side connection for second Schottky diode; enables dual-input redundancy or dual-rail protection. |
| 3 | Common Cathode (K1/K2) | Shared output/negative-side node; simplifies PCB layout by consolidating return path and enhancing thermal dissipation through large copper area. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS power supplies. |
| Low VF Schottky architecture | 360–390 mV drop at 0.5 A reduces conduction loss by >40% vs. standard silicon diodes, extending battery runtime. |
| Integrated guard ring | Enhances ruggedness against mechanical stress and voltage transients during reflow and in-circuit operation. |
| Common-cathode dual-diode topology | Enables compact reverse-polarity protection for dual-input systems (e.g., primary + backup supply) without extra components. |
| Thermally optimized SOT23 | Supports up to 460 mW total power dissipation on ceramic PCB, allowing higher current density than standard FR4 layouts. |
Applications
| Automotive Power Rail Protection | USB-C Port Reverse Polarity Guard |
|---|---|
|
Use Scenario: Protecting 12 V vehicle subsystems (e.g., infotainment, lighting ECUs) from battery misconnection during service or jump-start events. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier acting as fail-safe input clamp; conducts only when polarity is correct, blocking reverse current. Use Value: Prevents catastrophic damage to downstream regulators and microcontrollers without adding series resistance or active circuitry. |
Use Scenario: Safeguarding USB-C receptacles in portable automotive accessories (e.g., dashcams, tire-pressure monitors) against accidental reversed cable insertion. IC Role / Device Role / Timing Role: Common-cathode dual diode providing independent protection for VBUS and CC lines while minimizing footprint. Use Value: Eliminates need for separate diodes per line, reducing BOM count and PCB area by 33% versus discrete solutions. |
| High-Frequency DC-DC Converter Output | Low-Power IoT Sensor Supply Rectification |
|
Use Scenario: Output rectification in 2–5 MHz buck converters powering automotive radar MMICs or camera image sensors. IC Role / Device Role / Timing Role: Low-trr Schottky diode replacing synchronous MOSFETs in cost-sensitive designs where gate drive complexity must be avoided. Use Value: Delivers 22 ns recovery with no tail current, reducing switching node ringing and enabling stable regulation below 100 mV ripple. |
Use Scenario: Rectifying energy harvested from piezoelectric or thermoelectric sources in batteryless industrial wireless sensors. IC Role / Device Role / Timing Role: Ultra-low VF diode maximizing voltage transfer from sub-100 mV AC sources into supercapacitor storage. Use Value: 360 mV VF at 100 µA enables usable output even at 200 mV input amplitude - impossible with standard silicon diodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Single-diode SOD-323 package; 30 V VR, 500 mA IF(AV); VF = 450 mV @ 0.5 A. | Lacks dual-anode configuration; requires two devices for common-cathode functionality. | Choose when board space allows separate placement and higher VR margin is needed over low VF priority. |
| NSR20F30NXT5G | Dual common-cathode SOD-523; 30 V VR, 200 mA IF(AV); VF = 370 mV @ 0.2 A. | Lower current rating limits use to sub-200 mA rails; smaller footprint but reduced thermal mass. | Prefer for ultra-compact wearables or space-constrained modules where 0.2 A suffices and SOD-523 assembly is established. |
Compared with RB050M-30 and NSR20F30NXT5G, the PMEG2005CT-QR uniquely balances AEC-Q101 compliance, 0.5 A dual-current capability, and 360 mV VF in SOT23 - making it the only drop-in solution for automotive 12 V rail protection requiring both robustness and efficiency at minimal footprint.

FAQ
Is PMEG2005CT-QR suitable for 24 V truck electrical systems?
No - its 20 V reverse voltage rating makes it unsuitable for nominal 24 V systems where load dump transients exceed 30 V. It is rated for 12 V automotive applications only, with validated operation up to 20 V DC blocking. For 24 V systems, consider Nexperia's PMEG3005CT-Q (30 V VR) or equivalent.
Can Pin 1 and Pin 2 be paralleled for higher current?
No - Pins 1 and 2 are independent anodes connected to separate internal diodes sharing only the cathode (Pin 3). Paralleling them does not increase current rating, as each diode remains limited to 0.5 A IF(AV). Thermal coupling and mismatched VF may cause current imbalance and premature failure.
What is the maximum allowable soldering temperature profile?
The device complies with JEDEC J-STD-020D for moisture sensitivity level 1 (MSL1) and supports peak reflow temperatures up to 260 °C for 30 seconds. Wave soldering is permitted with preheat ≤150 °C and contact time ≤5 seconds, per Nexperia's SOT23 footprint guidelines (Fig. 17).
Does the "-QR" suffix indicate tape-and-reel packaging?
Yes - the "-QR" suffix denotes that the part is supplied in 3,000-unit tape-and-reel format per IEC 60286-3 standard, compatible with high-speed pick-and-place equipment. The base type number PMEG2005CT-Q refers to the device itself; "-QR" specifies packaging and ordering variant.
