Product details
Overview
BAS30LSYL from Nexperia is a high-speed switching diode in a DFN1006BD-2 (SOD882BD) leadless ultra-small SMD package, featuring 300 V repetitive peak reverse voltage (VRRM), ≤50 ns reverse recovery time (trr), and ≤2 pF junction capacitance (Cd). It serves as a fast-recovery clamping or polarity protection device in DC-DC converter flyback snubbers and USB power input stages.
For engineers reviewing the BAS30LSYL datasheet, BAS30LSYL pinout, BAS30LSYL application, or BAS30LSYL equivalent, key selection criteria include verified trr ≤50 ns at IF = 30 mA/IR = 30 mA, IR ≤150 nA at VR = 250 V and 25 °C, and thermal resistance Rth(j-a) = 375 K/W on standard FR4 PCB - critical for compact power rail protection designs.
Technical Context
This diode employs a planar epitaxial silicon structure optimized for rapid carrier recombination, enabling sub-50 ns reverse recovery under defined test conditions (IF = 30 mA, IR = 30 mA, RL = 100 Ω, IR(meas) = 3 mA). Its low Cd ≤2 pF at 1 MHz and VR = 0 V minimizes signal distortion in high-frequency clamp paths.
The DFN1006BD-2 package integrates side-wettable flanks for automated optical inspection (AOI) of solder joints and supports reflow-compatible footprint per Figure 10 (1.0 mm × 0.6 mm body, 0.65 mm pitch). Thermal performance is specified for single-sided 70 µm tin-plated copper on FR4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum repetitive reverse voltage before breakdown; enables use in 24 V–48 V industrial bus clamping with 6× safety margin. |
| trr | ≤50 ns - Measured under standardized square-wave switching; ensures minimal switching loss in 100 kHz–1 MHz DC-DC snubbers. |
| Cd | ≤2 pF at 1 MHz, VR = 0 V - Low junction capacitance preserves signal integrity in RF-coupled clamp nodes and high-edge-rate logic protection. |
| IR | ≤150 nA at VR = 250 V, Tj = 25 °C - Ultra-low leakage maintains efficiency in battery-backed or energy-harvesting hold-up circuits. |
| VF | 1.25 V at IF = 200 mA - Forward voltage drop defines conduction loss in reverse-polarity protection paths at rated current. |
| Rth(j-a) | 375 K/W - Junction-to-ambient thermal resistance on standard FR4; determines max continuous power dissipation (610 mW at Tamb ≤25 °C). |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), ultra-small leadless plastic SMD with side-wettable flanks, 1.0 mm × 0.6 mm × 0.47 mm body, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node in reverse-polarity protection; marked on top surface; requires thermal pad connection for optimal Rth(j-a). |
| 2 | Anode (A) | Connected to lower-potential node (e.g., GND or return path); forms forward conduction path when anode > cathode by ≥1.1 V. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤50 ns enables efficient operation up to 1 MHz in flyback snubbers without excessive ringing or EMI. |
| Low capacitance | Cd ≤2 pF minimizes loading on high-impedance signal lines during clamping, preserving rise/fall times in data-line protection. |
| Side-wettable flanks | Enables AOI verification of solder joint quality on both cathode and anode terminations - critical for automotive and medical manufacturing traceability. |
| Ultra-small footprint | 1.0 mm × 0.6 mm body allows placement in space-constrained USB-C PD input stages and wearable power management modules. |
Applications
| USB Power Input Protection | DC-DC Converter Snubber |
|---|---|
Use Scenario: Reverse polarity protection on 5 V–20 V USB-C PD input rails subject to hot-plug transients. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between connector and buck controller input; conducts only during correct insertion. Use Value: VF = 1.25 V at 200 mA limits voltage drop and heat generation; IR ≤150 nA prevents battery drain in standby. |
Use Scenario: Clamp voltage spikes across primary-side MOSFETs in 300 kHz–1 MHz isolated flyback converters. IC Role / Device Role / Timing Role: Fast-recovery snubber diode absorbing leakage inductance energy during MOSFET turn-off. Use Value: trr ≤50 ns ensures full recovery before next switching cycle, preventing shoot-through and secondary oscillation. |
| Voltage Clamping in Sensor Interfaces | Industrial I/O Signal Conditioning |
Use Scenario: Protecting 3.3 V analog sensor inputs (e.g., RTD, thermocouple amps) from ±15 V ESD or cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance clamp diode tied between signal line and supply rail; conducts only during overvoltage. Use Value: Cd ≤2 pF avoids bandwidth reduction in 100 kHz sensor bandwidths; VRRM = 300 V accommodates high-energy transients. |
Use Scenario: Polarity reversal safeguard on 24 V PLC digital input modules exposed to field wiring errors. IC Role / Device Role / Timing Role: Series-connected protection diode in front of optocoupler input; blocks reverse current during miswiring. Use Value: IF = 250 mA rating supports sustained 24 V/10 mA input current; Rth(j-a) = 375 K/W allows operation without heatsink at 50 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230P2T5G | Same VRRM = 30 V (not 300 V); trr = 4 ns (faster); Cd = 3.5 pF (higher); SOD-923 package (0.8 mm × 0.6 mm). | Only suitable for ≤30 V systems; inadequate for 48 V industrial clamping or 24 V reverse polarity where 300 V margin is required. | Select only if system VR < 30 V and trr < 10 ns is mandatory; verify layout clearance for lower VRRM. |
| Vishay ES1D-E3/61T | VRRM = 200 V (lower); trr = 35 ns; Cd = 30 pF (much higher); DO-214AC (SMA) package (4.5 mm × 2.7 mm). | Larger footprint incompatible with space-constrained designs; higher Cd degrades high-frequency signal integrity. | Acceptable only in non-miniaturized 24 V AC/DC adapters where board area is unconstrained and 200 V margin suffices. |
Compared with NSR0230P2T5G and ES1D-E3/61T, BAS30LSYL uniquely balances 300 V VRRM, ≤50 ns trr, ≤2 pF Cd, and 1.0 mm × 0.6 mm DFN packaging - making it the only option qualified for miniaturized 48 V industrial clamping with AOI-solder assurance.

FAQ
What is the maximum continuous forward current rating for BAS30LSYL?
The maximum continuous forward current (IF) is 250 mA at Tj = 25 °C on a standard FR4 PCB with single-sided 70 µm copper and tin-plated footprint. At elevated junction temperatures, derating applies per the thermal resistance specification (Rth(j-a) = 375 K/W).
Does BAS30LSYL support Automated Optical Inspection (AOI)?
Yes - its DFN1006BD-2 package features side-wettable flanks explicitly designed for AOI verification of solder joint quality on both anode and cathode terminals, as confirmed in Section 2 of the official Nexperia datasheet.
What is the reverse recovery time test condition for BAS30LSYL?
trr is measured under IF = 30 mA, IR = 30 mA, RL = 100 Ω, IR(meas) = 3 mA, and Tamb = 25 °C, using the test circuit shown in Figure 8 of the datasheet with RS = 50 Ω and sampling oscilloscope capture.
Is BAS30LSYL suitable for automotive applications?
No - the official Nexperia datasheet states this device is not automotive-qualified. It is not tested or warranted for AEC-Q101 stress requirements, and its qualification is limited to industrial and consumer applications per Section 15 (Legal information).
