Product details
Overview
BAS70XY-Q from Nexperia is a general-purpose quadruple Schottky diode in SOT363-3 (SC-88) package, configured as four independent low-capacitance diodes with 70 V reverse voltage rating, 410 mV forward voltage at 1 mA, and 100 nA reverse leakage at 50 V. It serves as ultra-high-speed clamping and switching elements in automotive signal conditioning circuits.
For engineers reviewing the BAS70XY-Q datasheet, BAS70XY-Q pinout, BAS70XY-Q application, or BAS70XY-Q equivalent, key selection criteria include its AEC-Q101 qualification, 2 pF diode capacitance at 0 V, 70 mA continuous forward current capability, and dual-anode/dual-cathode pin mapping for compact layout in space-constrained ECU front-end protection networks.
Technical Context
This quadruple Schottky diode integrates four discrete junctions in one monolithic die, sharing no internal connection between anodes or cathodes-each diode operates independently with isolated terminals. Its low 260 K/W junction-to-solder-point thermal resistance enables reliable operation up to 150 °C junction temperature under pulsed conditions.
The device uses platinum-silicide Schottky barrier technology to achieve fast recovery (< 1 ns), minimal stored charge, and stable VF across −40 °C to +125 °C ambient. Pin configuration supports flexible routing: pins 1/6 serve as anode/cathode pairs for Diodes 1 & 2, while pins 3/4/5 provide cross-connected anodes and cathodes for Diodes 3 & 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping of transients up to ISO 7637-2 Pulse 1/2a in 12 V automotive systems |
| Forward Voltage (VF) | 410 mV @ 1 mA - minimizes conduction loss in low-current bias and sensing paths |
| Reverse Leakage (IR) | 100 nA @ 50 V - ensures negligible standby current in always-on vehicle modules |
| Diode Capacitance (Cd) | 2 pF @ 0 V, 1 MHz - preserves signal integrity in >500 MHz RF-coupled detection circuits |
| Thermal Resistance (Rth(j-sp)) | 260 K/W - enables direct PCB copper pour heat sinking without thermal vias in TSSOP6 footprint |
| Junction Temperature (Tj) | 150 °C max - rated for under-hood engine control unit environments |

|---|---|
Use Scenario: Protecting LIN transceiver I/O against load dump and ESD events in body control modules. IC Role / Device Role / Timing Role: Quadruple Schottky diode array providing bidirectional clamping on TX/RX lines and VCC/GND rails. Use Value: 70 V VR withstands ISO 7637-2 Pulse 1 (−100 V) and Pulse 2a (+100 V); 2 pF Cd avoids signal edge degradation at 20 kbaud. |
Use Scenario: Low-capacitance ESD suppression on USB 2.0 D+/D− differential pair in infotainment head units. IC Role / Device Role / Timing Role: Four independent Schottky paths shunting ±8 kV contact discharge to ground without distorting 480 Mbps data eye. Use Value: 100 nA IR prevents DC offset in receiver bias networks; 410 mV VF ensures clamping threshold stays below USB PHY overvoltage limits. |
| Engine Control Unit Sensor Interface | ADAS Camera Power Rail Clamp |
Use Scenario: Clamping analog sensor inputs (e.g., MAP, O2) against battery transients in engine bay ECUs. IC Role / Device Role / Timing Role: Discrete quad diode used in parallel with TVS for multi-stage overvoltage protection on 5 V reference lines. Use Value: 260 K/W Rth(j-sp) allows direct thermal coupling to ground plane; 150 °C Tj rating matches under-hood ambient extremes. |
Use Scenario: Preventing voltage overshoot on 3.3 V camera module power rail during hot-plug insertion in surround-view systems. IC Role / Device Role / Timing Role: Fast-switching Schottky array absorbing inductive kickback from LDO enable sequencing and camera lens actuator drivers. Use Value: 70 mA IF rating handles peak surge currents from 10 µF local decoupling caps; 750 mV VF @ 10 mA ensures low-voltage dropout during clamp activation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F70NXT5G | Higher VF (550 mV @ 1 mA), same 70 V VR, SOT-363 package, AEC-Q101 qualified | Less suitable for low-voltage bias networks due to higher forward drop | Prefer when higher surge current handling (150 mA IFSM) outweighs VF penalty |
| Diodes Incorporated BAV99WQ-7-F | Lower VR (60 V), identical 2 pF Cd, same pinout, AEC-Q101 qualified | Not rated for 12 V system load dump (requires external TVS augmentation) | Select only for 5 V domain applications where 70 V margin is unnecessary |
Compared with NSR20F70NXT5G and BAV99WQ-7-F, the BAS70XY-Q uniquely balances 70 V standoff, 410 mV VF, and 2 pF capacitance in an AEC-Q101-compliant quad configuration-making it optimal for mixed-voltage automotive interfaces requiring both precision clamping and signal fidelity.

FAQ
What is the maximum allowable soldering temperature profile for BAS70XY-Q?
The BAS70XY-Q is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature of 260 °C for ≤ 30 seconds. Its SOT363-3 package uses matte tin plating compatible with Type 3 solder paste and requires 2.65 mm × 2.35 mm reflow footprint per Figure 6 of the datasheet.
Can BAS70XY-Q replace single-diode SOT23 packages in existing designs?
No-BAS70XY-Q contains four independent Schottky diodes in fixed pinout (pins 1–6), not four copies of a single-diode function. Direct replacement requires PCB layout revision to accommodate TSSOP6 spacing and verify terminal mapping matches the original circuit topology.
Does BAS70XY-Q support bidirectional clamping on a single line?
Yes-by connecting pins 1 (A1) and 6 (K1/A2) to the protected line, and pins 2 (K2) and 5 (K3) to ground, Diodes 1 and 2 form a back-to-back pair enabling symmetrical ±70 V clamping without external components.
How does BAS70XY-Q perform under extended high-temperature operation?
At 125 °C ambient, VF increases to ~520 mV and IR rises to ~1 µA at 50 V-still within functional limits for most automotive clamping roles. Derating curves in Figures 1–2 confirm stable operation up to 150 °C junction temperature with appropriate PCB thermal design.
