Product details
Overview
BAS70L-Q from Nexperia is a general-purpose Schottky diode in a leadless ultra-small DFN1006-2 (SOD882) package, rated for 70 V reverse voltage, 70 mA repetitive peak forward current, and 410 mV forward voltage at 1 mA pulsed conditions; it serves as a high-speed clamping and switching element in automotive power rail protection circuits.
For engineers reviewing the BAS70L-Q datasheet, BAS70L-Q pinout, BAS70L-Q application, or BAS70L-Q equivalent, key selection criteria include its AEC-Q101 qualification, low 2 pF capacitance at 0 V, 100 nA reverse leakage at 50 V, thermal resistance of 500 K/W on FR4, and cathode-marked top-side orientation for automated optical inspection.
Technical Context
This Schottky diode leverages a planar epitaxial construction to achieve fast recovery with negligible minority-carrier storage, enabling operation up to 1 GHz small-signal frequencies. Its low 410 mV VF at 1 mA and 1 V at 15 mA supports efficient voltage clamping in low-power signal paths.
The device operates across −65 °C to +150 °C ambient and junction temperatures, with thermal resistance from junction to ambient measured at 500 K/W under standardized FR4 mounting. Reverse leakage remains below 10 µA at full 70 V VR and 25 °C, critical for maintaining signal integrity in battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - Withstands transient surges in 12 V/24 V automotive supply rails without breakdown. |
| Forward Voltage (VF) | 410 mV @ 1 mA - Enables low-loss clamping in logic-level signal lines and I/O protection networks. |
| Reverse Leakage (IR) | 100 nA @ 50 V - Ensures minimal standby current drain in always-on vehicle modules. |
| Diode Capacitance (Cd) | 2 pF @ 0 V, 1 MHz - Preserves signal edge integrity in >100 MHz digital interfaces and RF bias networks. |
| Thermal Resistance (Rth(j-a)) | 500 K/W - Requires minimal PCB copper area for thermal management in space-constrained modules. |
| Package | DFN1006-2 (SOD882), 1.0 mm × 0.6 mm × 0.48 mm - Supports 0201-class board density for ADAS sensor nodes and infotainment SoC power domains. |
Pinout & Package
DFN1006-2 (SOD882) is a 2-terminal, leadless, surface-mount plastic package with exposed die pad not connected internally; body dimensions are 1.02 mm × 0.62 mm × 0.48 mm, cathode identified by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to reference node or ground side in clamping configuration; marked side on top view. |
| 2 | Anode (A) | Connected to protected signal line or positive rail; polarity must be verified before reflow soldering. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114. |
| Ultra-low capacitance | 2 pF enables use in USB 2.0 data line ESD protection without signal degradation. |
| High-speed switching | Sub-nanosecond reverse recovery supports >500 MHz clock signal routing and RF detector applications. |
| Low forward voltage | 410 mV at 1 mA reduces conduction loss in low-current bias networks for op-amp input stages. |
Applications
| Automotive CAN Transceiver Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protects CAN_H/CAN_L pins against ISO 7637-2 load dump transients and ESD events in body control modules. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed between differential pair and ground, limiting voltage excursions to ±15 V. Use Value: 70 V VR rating and 100 nA IR ensure no DC loading on bus while surviving 100 V spikes per ISO standard. | Use Scenario: Shields USB 2.0 D+ and D− lines from IEC 61000-4-2 contact discharge in infotainment head units. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp that activates within 1 ns to divert ESD current away from PHY inputs. Use Value: 2 pF capacitance avoids signal rise-time degradation beyond USB 2.0's 200 ps requirement. |
| Low-Power Sensor Bias Network | RF Detector Input Protection |
Use Scenario: Provides reverse-polarity and overvoltage protection for analog sensor outputs in tire pressure monitoring systems (TPMS). IC Role / Device Role / Timing Role: Series-connected Schottky used to block backfeed from downstream ADC reference while passing 1–10 µA sensor currents. Use Value: 410 mV VF ensures <1 mV error contribution at 2.5 V rail, preserving 12-bit measurement accuracy. | Use Scenario: Guards mixer LO port and detector diode anode in UWB radar front-ends operating at 6–10 GHz. IC Role / Device Role / Timing Role: High-frequency shunt limiter that attenuates out-of-band RF energy before sensitive detector junctions. Use Value: Sub-1 nH parasitic inductance and 2 pF Cd maintain impedance match up to 12 GHz per S-parameter modeling. |
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 NSR0230HT1G | Same DFN1006-2 package but 30 V VR rating and 390 mV VF @ 1 mA. | Limited to 5 V logic rails; unsuitable for 12 V automotive clamping. | Select only for cost-sensitive consumer USB ports where 70 V margin is unnecessary. |
| Vishay VS-2EDH01HM3/H | TO-236AB (SOT-23) package, 70 V VR, but 500 mV VF @ 1 mA and 5 pF capacitance. | Higher parasitics limit use to <100 MHz applications; incompatible with 0201 board space. | Choose when manual rework or legacy footprint compatibility outweighs RF performance needs. |
Compared with NSR0230HT1G and VS-2EDH01HM3/H, the BAS70L-Q uniquely balances 70 V robustness, 2 pF capacitance, and DFN1006-2 size-making it the only option qualified for AEC-Q101 and validated for >100 MHz signal integrity in space-constrained automotive modules.

FAQ
Is BAS70L-Q suitable for bidirectional ESD protection?
No. The BAS70L-Q is a unidirectional Schottky diode with anode and cathode terminals; for bidirectional ESD protection, a paired configuration (e.g., two devices in series opposition) or a dedicated TVS diode such as PESD5V0S1BA must be used. Its single-junction structure only conducts in one direction.
What is the maximum allowable soldering temperature profile for BAS70L-Q?
The BAS70L-Q requires reflow soldering only, per JEDEC J-STD-020. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. Wave or hand soldering is not recommended due to thermal stress on the ultra-thin DFN1006-2 package.
Does the marking 'S8' correspond to BAS70L-Q across all production lots?
Yes. Per Nexperia's marking code table, 'S8' is the unique top-side laser marking for BAS70L-Q across all qualified production lots. No alternate markings or date codes are used for this part number; visual inspection of the cathode bar and 'S8' confirms authenticity.
Can BAS70L-Q replace BAS70-04 in existing designs?
No. BAS70-04 is a quad-Schottky array in SOT-363, while BAS70L-Q is a single diode in DFN1006-2. Pin count, package footprint, thermal behavior, and electrical parameters differ significantly; direct replacement would require PCB redesign and layout validation for signal integrity and thermal dissipation.
