Product details
Overview
BAS30LS-QYL from Nexperia is a high-speed switching diode in a DFN1006BD-2 (SOD882BD) leadless SMD package, rated for 300 V repetitive peak reverse voltage, 250 mA forward current, and 50 ns reverse recovery time. It serves as a fast-recovery clamping or polarity protection device in automotive power management circuits, including DC-DC converter flyback paths and battery input stages.
For engineers reviewing the BAS30LS-QYL datasheet, BAS30LS-QYL pinout, BAS30LS-QYL application, or BAS30LS-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for AOI-compatible solder joint inspection, 2 pF capacitance at 1 MHz, and thermal resistance of 375 K/W on standard FR4 PCBs.
Technical Context
This diode operates as a unidirectional, silicon-based PN junction switch optimized for rapid turn-off under inductive load conditions. Its trr ≤ 50 ns is measured with IF = IR = 30 mA, RL = 100 Ω, and IR(meas) = 3 mA at Tamb = 25 °C - confirming suitability for >1 MHz switching topologies.
The DFN1006BD-2 package features side-wettable flanks enabling automated optical inspection of solder fillets, while its 1.0 mm × 0.6 mm × 0.47 mm body and 0.65 mm pitch support ultra-dense automotive PCB layouts. Junction temperature is rated to 150 °C, with storage range from −65 °C to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR / VRRM | 300 V - supports 24 V and 48 V automotive systems with ≥2× safety margin against transients like load dump. |
| IF(max) | 250 mA - sufficient for signal-level clamping and low-power rail protection without derating on standard FR4. |
| trr | ≤50 ns - enables clean commutation in PWM frequencies up to 1–2 MHz without excessive switching loss. |
| Cd | ≤2 pF at VR = 0 V, f = 1 MHz - minimizes capacitive loading in high-impedance sensing or timing nodes. |
| IR | 150 nA at VR = 250 V, Tj = 25 °C - ensures negligible leakage in always-on bias networks or precision reference paths. |
| Rth(j-a) | 375 K/W - defines thermal rise under continuous DC operation on single-sided 70 µm copper FR4 with standard footprint. |
Pinout & Package
Encapsulated in the DFN1006BD-2 (SOD882BD) package: ultra-small, leadless, 1.0 mm × 0.6 mm × 0.47 mm body, 0.65 mm pitch, side-wettable flanks, cathode-marked top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node during forward conduction; marking side on top surface identifies this terminal. |
| 2 | Anode (A) | Connected to lower-potential node; current flows from Pin 2 to Pin 1 when forward-biased. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements - eliminates need for additional qualification by Tier-1 suppliers. |
| Side-wettable flanks | Enables reliable Automated Optical Inspection (AOI) of solder joints without X-ray - reduces post-reflow defect escape rate. |
| Low trr (≤50 ns) | Reduces reverse recovery charge (Qrr), minimizing EMI and shoot-through risk in synchronous rectifier or clamp circuits. |
| Low Cd (≤2 pF) | Preserves signal integrity in RF-coupled or high-frequency feedback paths where parasitic capacitance degrades phase margin. |
| Ultra-small DFN1006BD-2 | Occupies 0.6 mm² PCB area - ideal for space-constrained ADAS sensor modules and compact ECU power rails. |
Applications
| DC-DC Converter Clamp Diode | Automotive Reverse Polarity Protection |
|---|---|
Use Scenario: Placed across primary-side snubber or secondary-side flyback clamp in 48 V automotive DC-DC converters operating at 500 kHz–1 MHz. IC Role / Device Role / Timing Role: Fast-recovery clamping diode absorbing inductive energy during MOSFET turn-off. Use Value: 50 ns trr and 300 V rating prevent voltage overshoot beyond 40 V rail tolerance while maintaining efficiency above 92%. |
Use Scenario: Series-connected at battery input of infotainment head unit to block reverse connection during service or jump-start events. IC Role / Device Role / Timing Role: Unidirectional blocking element conducting only during correct polarity insertion. Use Value: 150 nA IR at 250 V ensures <1 µW standby power loss; AEC-Q101 rating guarantees reliability over 15-year vehicle lifecycle. |
| High-Speed Signal Clamping | Engine Control Unit (ECU) Input Protection |
Use Scenario: Dual-diode clamp on CAN FD transceiver I/O lines to limit ESD-induced overvoltage to ±30 V. IC Role / Device Role / Timing Role: Low-capacitance (2 pF) transient voltage limiter preserving signal edge integrity. Use Value: Sub-2 pF capacitance avoids signal distortion at 5 Mbps CAN FD data rates; 300 V VR withstands ISO 7637-2 pulse 5a. |
Use Scenario: Input-stage protection for microcontroller GPIOs monitoring crankshaft position sensor signals in engine bay environments. IC Role / Device Role / Timing Role: High-reliability, thermally robust switching diode in harsh ambient (−40 °C to 125 °C). Use Value: 150 °C Tj rating and −65 °C to 150 °C Tstg ensure uninterrupted operation during cold cranking and exhaust heat exposure. |
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 NSR30CM3T5G | Same DFN1006BD-2 package, but trr = 35 ns (typ), VF = 1.05 V @ 200 mA, IR = 200 nA @ 250 V. | Slightly faster recovery and lower VF, but higher leakage may impact ultra-low-power always-on circuits. | Select when minimizing conduction loss is prioritized over leakage-critical bias networks. |
| Vishay VS-30BQ015-M3/84 | TO-277 package (larger), 15 V VR, Schottky architecture, VF = 0.45 V @ 3 A - not a direct replacement. | Used in high-current, low-VF applications (e.g., OR-ing), not high-voltage clamping. | Not suitable for 300 V clamping roles; consider only for low-voltage, high-current rectification where VR < 20 V. |
Compared with NSR30CM3T5G, BAS30LS-QYL offers lower leakage and identical package compatibility but trades 15 ns slower trr; versus VS-30BQ015-M3/84, it provides 20× higher VR rating and SMT miniaturization at the cost of higher VF - making it the sole viable choice for 300 V automotive clamping in space-constrained designs.

FAQ
Is BAS30LS-QYL pin-compatible with BAS216 or BAS16?
No. BAS30LS-QYL uses a 2-pin DFN1006BD-2 package with side-wettable flanks, while BAS216 and BAS16 are in SOT23 packages with three pins and different pinouts. Physical mounting, thermal path, and solder inspection methods are incompatible - no mechanical or electrical drop-in replacement exists.
What is the maximum allowable PCB copper area for thermal relief on the cathode pad?
The datasheet specifies two thermal test conditions: standard footprint (no added copper) yields Rth(j-a) = 375 K/W, while a 1 cm² cathode-side copper pad reduces it to 205 K/W. For production use, the 1 cm² pad is permitted and recommended to sustain 250 mA continuous current at Tamb = 85 °C without exceeding Tj = 150 °C.
Does BAS30LS-QYL support reflow soldering per JEDEC J-STD-020?
Yes. Nexperia qualifies the DFN1006BD-2 package for lead-free reflow per JEDEC J-STD-020D, with peak temperature of 260 °C for ≤30 seconds. The footprint in Figure 10 (sod882bd_fr) and solder paste stencil design are aligned to this standard, and side-wettable flanks enable post-reflow AOI verification.
Can BAS30LS-QYL be used in AC line rectification?
No. With VR = 300 V and IF = 250 mA, it is unsuitable for mains AC rectification (e.g., 120/230 V RMS), which requires ≥600 V PIV and higher surge current ratings (e.g., IFSM ≥ 30 A). Its design targets low-energy, high-frequency clamping and protection - not bulk power conversion.
