Product details
Overview
BAT42LS-QYL from Nexperia is a general-purpose Schottky diode in DFN1006BD-2 (SOD882BD) package, rated for 200 mA forward current and 40 V reverse voltage, with typical 600 mV forward voltage at 200 mA and 25 °C. It serves as a low-loss rectifier or clamping device in space-constrained automotive and portable electronics.
For engineers reviewing the BAT42LS-QYL datasheet, BAT42LS-QYL pinout, BAT42LS-QYL application, or BAT42LS-QYL equivalent, key selection criteria include ultra-low VF at low IF, AEC-Q101 qualification, side-wettable flanks for AOI-compatible solder joint inspection, and thermal resistance of 205 K/W on optimized PCB layout.
Technical Context
This Schottky diode uses a planar epitaxial construction to achieve low forward voltage and fast switching recovery (<1 ns), enabling use in high-frequency clamping and low-voltage rectification where conduction loss must be minimized. Its junction temperature rating of 150 °C supports operation in under-hood automotive environments.
The device exhibits 20 pF capacitance at 1 V reverse bias and 1 MHz, and reverse leakage remains ≤10 µA at 40 V and 25 °C - critical for maintaining efficiency in battery-powered protection circuits and blocking configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 600 mV at 200 mA, 25 °C - enables <120 mW conduction loss in 3.3 V rail clamping |
| Reverse Voltage (VR) | 40 V maximum - suitable for 24 V automotive supply rail transient suppression |
| Forward Current (IF) | 200 mA continuous - supports low-power signal path rectification without derating |
| Diode Capacitance (Cd) | 20 pF at 1 V, 1 MHz - preserves signal integrity in <100 MHz digital I/O protection |
| Reverse Leakage (IR) | ≤10 µA at 40 V, 25 °C - ensures minimal standby power drain in always-on circuits |
| Junction Temperature (Tj) | 150 °C max - allows operation in engine control unit (ECU) ambient up to 125 °C |
| Thermal Resistance (Rth(j-a)) | 205 K/W with 1 cm² cathode pad - defines PCB copper area needed for thermal compliance |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm, featuring side-wettable flanks for automated optical inspection of solder joints. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to lower-potential node; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to higher-potential node; current flows from Pin 2 to Pin 1 when forward-biased |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including body control modules and infotainment power rails |
| Side-wettable flanks | Enables reliable AOI detection of solder fillet quality on both sides of the package edge |
| Low VF across temperature | 650 mV max at −40 °C/200 mA - maintains clamping effectiveness in cold-start conditions |
| Ultra-small footprint | 0.6 mm pitch, 0.6 mm width - fits within tight spacing constraints of wearable and ADAS sensor PCBs |
| Pulsed current capability | 3 A non-repetitive peak - handles ESD-induced transients without degradation |
Applications
| Automotive Body Control Module | USB-C Port Protection |
|---|---|
Use Scenario: Reverse polarity protection on 12 V supply input to door module MCU. IC Role / Device Role / Timing Role: Blocking diode preventing damage during battery jump-start misconnection. Use Value: 600 mV VF limits voltage drop to <5% at 200 mA load, preserving brown-out margin for 5 V LDO input. |
Use Scenario: VBUS line clamping against ±15 kV ESD events per IEC 61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance shunt path diverting ESD current away from USB controller pins. Use Value: 20 pF capacitance avoids signal integrity degradation on 480 Mbps full-speed USB data lines. |
| Portable Medical Sensor Node | Industrial IoT Wireless Transceiver Power Rail |
Use Scenario: Low-power rectification of harvested energy from piezoelectric transducer. IC Role / Device Role / Timing Role: AC-to-DC conversion stage feeding microampere-level charging circuit. Use Value: 290 mV VF at 1 mA enables usable output above 300 mV input - critical for sub-1 V energy harvesting. |
Use Scenario: Isolation between main 3.3 V rail and LoRaWAN radio's sensitive RF section. IC Role / Device Role / Timing Role: Blocking diode preventing backfeed during radio transmit burst current surges. Use Value: 200 mA continuous rating sustains >100 ms transmit duty cycle without thermal shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230P2T5G | Same DFN1006 package, but VF = 450 mV typ at 200 mA - 150 mV lower than BAT42LS-QYL | Higher leakage (30 µA at 40 V) - less suitable for battery-critical standby modes | Select when lowest conduction loss dominates; verify IR impact on system quiescent current. |
| Vishay VS-2EDH02HM3/85A | SOD-123FL package (larger), VR = 20 V only - not interchangeable in 24 V systems | Not AEC-Q101 qualified - requires requalification for automotive deployment | Use only in cost-sensitive industrial applications where 40 V rating and automotive qualification are not required. |
Compared with NSR0230P2T5G and VS-2EDH02HM3/85A, BAT42LS-QYL uniquely balances AEC-Q101 compliance, 40 V rating, side-wettable flanks, and 600 mV VF - making it optimal for space-limited automotive subsystems requiring production-grade AOI validation.

FAQ
What is the maximum allowable junction temperature for BAT42LS-QYL?
The absolute maximum junction temperature is 150 °C, as defined in the limiting values table. Operation beyond this temperature risks permanent parametric shift or catastrophic failure. Derating is required above 25 °C ambient, with thermal resistance of 205 K/W measured on a 1 cm² cathode pad - actual Tj must be calculated using measured power dissipation and board layout.
Does BAT42LS-QYL support automatic optical inspection (AOI)?
Yes - its DFN1006BD-2 package features side-wettable flanks, enabling AOI systems to inspect solder fillet formation on both lateral edges of the terminals. This is confirmed in Section 2 ("Features and benefits") and Section 13 ("Soldering") of the official Nexperia datasheet.
Is BAT42LS-QYL pin-compatible with BAT42WS?
No - BAT42WS uses SOD-323 package (2.7 mm × 1.7 mm), while BAT42LS-QYL uses DFN1006BD-2 (1.0 mm × 0.6 mm). Footprint, thermal pad layout, and soldering profile differ significantly; no mechanical or electrical interchangeability exists without PCB redesign.
What is the reverse leakage current at 40 V and 125 °C?
Per Figure 2 in the Nexperia datasheet, reverse leakage at VR = 40 V and Tamb = 125 °C is approximately 2.5 µA (typical), extrapolated from the curve showing ~0.5 µA at 25 °C and ~10 µA at 150 °C. This value is confirmed by the device's thermal characteristics and leakage trend across temperature.
