Product details
Overview
PMEG3005ET,215 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 0.5 A forward current, featuring a typical forward voltage of 380–430 mV at 500 mA, housed in a SOT23 surface-mount package. It serves as a low-loss anode-cathode switching element in DC-DC converters and polarity protection circuits.
For engineers reviewing the PMEG3005ET,215 datasheet, PMEG3005ET,215 pinout, PMEG3005ET,215 application, or PMEG3005ET,215 equivalent, key selection criteria include its ultra-low VF at low currents (215 mV at 10 mA), low reverse leakage (≤150 µA at 30 V), and thermal resistance of 300 K/W on optimized PCB layout - critical for compact, thermally constrained power rails.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low barrier height enables sub-430 mV conduction at rated current while maintaining 30 V reverse blocking capability.
The device operates within −65 °C to 150 °C junction temperature range and exhibits capacitance of 55–70 pF at 1 V reverse bias, making it suitable for high-frequency switching nodes where parasitic capacitance impacts efficiency and EMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - defines maximum allowable DC or peak AC reverse bias before breakdown; sets operating margin for 24 V system protection. |
| Forward Current (IF) | 0.5 A continuous - supports sustained load current in point-of-load regulators without derating at Tamb ≤ 25 °C. |
| Forward Voltage (VF) | 380–430 mV @ 500 mA - reduces conduction loss to <215 mW, enabling >95% efficiency in low-voltage synchronous rectifier alternatives. |
| Reverse Leakage (IR) | 40–150 µA @ 30 V - limits standby power loss in battery-backed or always-on circuits. |
| Diode Capacitance (Cd) | 55–70 pF @ 1 V - minimizes switching node ringing and gate drive loading in MHz-range DC-DC controllers. |
| Thermal Resistance (Rth(j-a)) | 300 K/W on 1 cm² cathode pad - enables 125 °C junction operation with only ~37.5 °C rise above ambient at full load. |
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 PMEG3005ET,215 features three terminals with Pin 2 internally unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Input terminal for forward conduction; connects to higher-potential side in rectification or polarity protection. |
| 2 | Not Connected (n.c.) | No internal bond wire or die connection; must remain floating or grounded per layout best practice to avoid parasitic coupling. |
| 3 | Cathode (K) | Output/return terminal; ties to ground or lower-potential rail; largest thermal pad area for heat dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge avalanche and improves surge robustness without increasing VF - critical for automotive-adjacent industrial power inputs. |
| Ultra-low VF at low IF | 215 mV @ 10 mA enables efficient start-up and light-load operation in energy-harvesting and IoT sensor nodes. |
| SOT23 footprint compatibility | Standard 3-pin SMT outline allows drop-in replacement in existing layouts designed for similar Schottky diodes (e.g., PMEG2005AE). |
| Non-automotive qualified | Rated for industrial and consumer applications only; not tested to AEC-Q101 - requires separate qualification for automotive use. |
Applications
| Low-Voltage Rectification | High-Efficiency DC-DC Conversion |
|---|---|
|
Use Scenario: Converting 5 V USB input to 3.3 V logic rail in portable instrumentation. IC Role / Device Role: Output rectifier in buck converter secondary stage. Use Value: 380 mV VF minimizes dropout and thermal rise, preserving >92% conversion efficiency at 300 mA load. |
Use Scenario: Synchronous rectifier replacement in 12 V → 1.8 V point-of-load module. IC Role / Device Role: Freewheeling diode during high-side FET off-time. Use Value: Low Cd (65 pF) reduces switching losses and EMI generation at 2 MHz switching frequency. |
| Inverse Polarity Protection | Low-Power Consumption Systems |
|
Use Scenario: Protecting 3.3 V microcontroller supply against accidental reverse battery insertion. IC Role / Device Role: Series-connected anode-to-input, cathode-to-rail blocking element. Use Value: 40 µA max IR at 3.3 V ensures <135 nW standby loss - negligible in battery life calculations. |
Use Scenario: Power path management in coin-cell–powered wearable sensors. IC Role / Device Role: Isolation diode between energy harvester and storage capacitor. Use Value: 150 mV VF at 100 µA enables usable output even below 0.5 V input - extends operational envelope. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | Higher VF (450 mV typ @ 500 mA); same 30 V VR; SOD-523 package (smaller, 1.2 mm × 0.8 mm). | Less thermal mass and higher Rth(j-a) (~450 K/W); unsuitable for >200 mA continuous in unventilated enclosures. | Select when board space is primary constraint and average current stays below 150 mA. |
| PMEG2005AE,115 | Lower VR (20 V); identical VF (380–430 mV), SOT23 package; automotive-qualified (AEC-Q101). | Not rated for 24 V systems; requires redesign if input transients exceed 20 V. | Choose only for automotive-grade designs where 20 V rating suffices and qualification is mandatory. |
Compared with RB520S-30T1G and PMEG2005AE,115, the PMEG3005ET,215 uniquely balances 30 V capability, ultra-low VF, and industrial-grade SOT23 thermal performance - making it optimal for space-constrained 24 V industrial power rails needing <0.5 A continuous conduction.

FAQ
Is PMEG3005ET,215 suitable for automotive applications?
No. The PMEG3005ET,215 is explicitly marked as non-automotive qualified in its revision history and legal disclaimers. It lacks AEC-Q101 qualification and has not undergone automotive-specific stress testing. For automotive use, Nexperia offers the PMEG2005AE,115 (20 V) or PMEG3015AE,115 (30 V, AEC-Q101 qualified) as direct alternatives.
What is the maximum pulsed forward current rating?
The PMEG3005ET,215 supports a non-repetitive peak forward current (IFSM) of 10 A for 8 ms square-wave pulses, and a repetitive peak forward current (IFRM) of 3.9 A with ≤1 ms pulse width and 50% duty cycle. These values assume FR4 PCB mounting with specified copper area per datasheet Section 8.
How does the guard ring affect reliability?
The integrated guard ring mitigates electric field crowding at the silicon periphery, raising the effective reverse breakdown voltage margin and improving resistance to ESD and line-transient-induced edge avalanche. This directly extends operational lifetime in environments with frequent voltage surges or hot-plug events.
Can Pin 2 be used as a thermal pad or grounded?
No. Pin 2 is explicitly designated "not connected" in Table 2 and has no internal die connection. Using it as a thermal pad or grounding it introduces risk of solder bridging, unintended coupling, or mechanical stress on the mold compound. It must remain electrically isolated per Nexperia's recommended footprint and assembly guidelines.
