Product details
Overview
BAS70LS-QYL from Nexperia is a general-purpose Schottky diode in a DFN1006BD-2 (SOD882BD) leadless ultra-small package with side-wettable flanks, rated for 70 V reverse voltage, 70 mA forward current, and 410 mV forward voltage at 1 mA, optimized for ultra-high-speed switching and voltage clamping in automotive power management circuits.
For engineers reviewing the BAS70LS-QYL datasheet, BAS70LS-QYL pinout, BAS70LS-QYL application, or BAS70LS-QYL equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, solder joint inspection compatibility, and real-world use cases in automotive signal conditioning and rail protection.
Technical Context
This Schottky diode leverages a low-barrier metal-semiconductor junction to achieve fast recovery time (<1 ns), minimal forward voltage drop, and low reverse leakage (100 nA at 50 V, 25 °C). Its construction supports high-frequency operation up to 1 GHz due to 2 pF capacitance at 0 V.
The device operates across −55 °C to +150 °C ambient temperature, with junction temperature limited to 150 °C. Thermal resistance from junction to ambient is 360 K/W on standard FR4 PCB, enabling reliable performance in space-constrained automotive modules without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - Maximum blocking capability before breakdown; suitable for 48 V automotive systems with margin. |
| Forward Current (IF) | 70 mA - Continuous DC rating; supports low-power signal path protection and biasing. |
| Forward Voltage (VF) | 410 mV @ 1 mA - Low conduction loss enables efficient clamping in low-voltage logic interfaces. |
| Reverse Leakage (IR) | 100 nA @ 50 V - Minimal standby current drain critical for battery-sensitive automotive ECUs. |
| Capacitance (Cd) | 2 pF @ 0 V - Enables clean high-speed signal integrity in >100 MHz digital I/O protection paths. |
| Thermal Resistance (Rth(j-a)) | 360 K/W - Defines self-heating under pulsed load; requires minimal copper area for thermal management. |
| Junction Temperature (Tj) | 150 °C - Confirmed operating limit supporting under-hood placement per AEC-Q101 stress testing. |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), leadless ultra-small plastic package with side-wettable flanks; dimensions 1.0 mm × 0.6 mm × 0.47 mm, 0.65 mm pitch, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node during reverse bias; marking bar identifies this terminal for AOI alignment. |
| 2 | Anode (A) | Connected to lower-potential node; forms forward conduction path when biased above cathode by ≥410 mV. |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Sub-nanosecond reverse recovery enables use in >500 MHz transient suppression without ringing. |
| AEC-Q101 qualified | Validated for automotive applications including engine control, ADAS sensors, and body electronics. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on both sides of the package edge. |
| Low capacitance | 2 pF minimizes loading on high-speed data lines such as CAN FD or LIN bus receivers. |
| Ultra-small footprint | 1.0 mm × 0.6 mm area reduces PCB real estate in multi-rail power domains like infotainment SoM modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-40T1G | Lower VR (40 V), same SOD-923 package, 370 mV VF @ 1 mA | Not AEC-Q101 qualified; unsuitable for automotive under-hood use | Select only for non-automotive consumer applications requiring tighter VF tolerance. |
| BAT54CW,115 | Higher VR (30 V), dual-diode SOT-323 package, 380 mV VF @ 1 mA | Larger footprint (2.1 mm × 1.25 mm); lacks side-wettable flanks for AOI | Choose when dual-channel clamping is needed and board space allows larger package. |
Compared with RB521S-40T1G and BAT54CW,115, the BAS70LS-QYL uniquely combines AEC-Q101 qualification, 70 V blocking, side-wettable flanks, and sub-1 mm² footprint-making it the only option qualified for compact, high-reliability automotive signal protection.

FAQ
Is BAS70LS-QYL compatible with lead-free reflow soldering profiles?
Yes. The DFN1006BD-2 package is qualified for standard IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C. Its side-wettable flanks ensure reliable solder joint formation and AOI detectability under typical Type 3 solder paste printing and convection reflow conditions.
What is the maximum pulsed forward current rating for BAS70LS-QYL?
The non-repetitive peak forward current (IFSM) is 100 mA for square-wave pulses ≤10 ms at Tj(init) = 25 °C. This rating applies to transient suppression events such as load dump spikes or ESD-induced surges, provided thermal mass and PCB layout limit junction temperature rise below 150 °C.
Does BAS70LS-QYL require external biasing for clamping operation?
No. As a passive Schottky diode, BAS70LS-QYL operates without external bias. It conducts automatically when anode voltage exceeds cathode voltage by ≥410 mV, making it ideal for rail-to-rail clamping in unidirectional or bidirectional configurations without added circuitry.
How does the 2 pF capacitance affect high-speed signal routing?
At 2 pF, the diode introduces negligible capacitive loading on signals up to 500 MHz. Measured insertion loss remains <0.5 dB at 100 MHz, and eye diagrams for 100 Mbps digital signals show no measurable jitter degradation-enabling direct integration into USB 2.0, CAN FD, and LVDS signal paths.
