Product details
Overview
BAS70XY from Nexperia is a general-purpose quadruple Schottky diode in SOT363-3 (TSSOP6) package, configured as four independent low-capacitance diodes with shared anode/cathode terminals. It delivers 70 V reverse voltage rating, 410 mV forward voltage at 1 mA, and 2 pF capacitance at 0 V - enabling ultra-high-speed switching and precise voltage clamping in compact DC-DC converter feedback paths.
For engineers reviewing the BAS70XY datasheet, BAS70XY pinout, BAS70XY application, or BAS70XY equivalent, this device is selected for space-constrained designs requiring simultaneous fast switching, low leakage (<100 nA at 50 V), and thermal robustness up to 150 °C junction temperature in multi-rail power management systems.
Technical Context
The BAS70XY integrates four discrete Schottky diodes in a single 6-pin TSSOP package with non-standard pin mapping: pins 1/6 share anode/cathode roles across diodes 1 and 2, while pins 3/5 serve dual anode/cathode functions for diodes 3 and 4. This configuration supports flexible bidirectional clamping or independent signal routing without external interconnects.
Its 260 K/W junction-to-solder-point thermal resistance is optimized for reflow-soldered PCBs with thermal relief on pins 2, 3, 5, and 6. The 100 mA non-repetitive peak forward current and 150 °C max junction temperature support transient surge handling in industrial power supervisors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - enables clamping in 48 V industrial bus interfaces without breakdown risk |
| Forward Voltage (VF) | 410 mV @ 1 mA - minimizes conduction loss in low-current bias networks |
| Reverse Current (IR) | 100 nA @ 50 V - ensures signal integrity in high-impedance analog sampling circuits |
| Diode Capacitance (Cd) | 2 pF @ 0 V - preserves bandwidth in >500 MHz RF detector front-ends |
| Thermal Resistance (Rth(j-sp)) | 260 K/W - requires thermal pads on pins 2/3/5/6 to maintain ≤125 °C junction under 70 mA DC load |
| Peak Forward Current (IFSM) | 100 mA @ 10 ms - sustains ESD pulse suppression in USB port protection without derating |
Pinout & Package
Package: SOT363-3 (TSSOP6), 2.2 mm × 1.35 mm × 0.95 mm body, 0.65 mm lead pitch, plastic surface-mount package with exposed solderable terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (D1) | Input node for first diode's forward conduction path; connects to positive rail in clamp configuration |
| 2 | Cathode (D2) | Return node for second diode; tied to ground reference in level-shifting applications |
| 3 | Anode (D3) / Cathode (D4) | Shared terminal enabling cross-coupled clamping between diodes 3 and 4 in bidirectional TVS layouts |
| 4 | Anode (D4) | Independent anode for fourth diode; used for separate bias injection in dual-supply monitoring |
| 5 | Cathode (D3) | Complementary cathode to pin 3; forms complete D3 path when paired with pin 3 as anode |
| 6 | Cathode (D1) / Anode (D2) | Dual-role terminal allowing D1 reverse recovery and D2 forward conduction in interleaved switching stages |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | Sub-nanosecond reverse recovery due to Schottky barrier construction - critical for >100 MHz clock signal conditioning |
| Low leakage current | 100 nA at 50 V reverse bias - prevents drift in precision voltage reference dividers |
| High breakdown voltage | 70 V rated VR - supports direct interface with 24/48 V industrial control I/O without series resistors |
| Low capacitance | 2 pF at zero bias - maintains signal rise time <1 ns in high-speed logic line termination |
Applications
| USB 2.0 Data Line Protection | DC-DC Converter Feedback Clamp |
|---|---|
|
Use Scenario: Clamping ESD transients on D+ and D− lines of embedded USB peripherals. IC Role / Device Role / Timing Role: Quad Schottky array provides independent bidirectional clamping per data line using pins 1/6 and 2/5 pairs. Use Value: 2 pF capacitance avoids signal integrity degradation at 480 Mbps; 70 V VR withstands ±15 kV contact discharge per IEC 61000-4-2. |
Use Scenario: Preventing op-amp saturation in isolated flyback converter feedback loops. IC Role / Device Role / Timing Role: Diodes 1 and 2 clamp error amplifier output to ±0.41 V, limiting optocoupler LED drive range. Use Value: 410 mV VF ensures tight voltage window; 100 nA IR eliminates offset error in high-gain compensation networks. |
| Multi-Rail Power Sequencing | RF Detector Bias Network |
|
Use Scenario: Enabling controlled startup order across +3.3 V, +5 V, and +12 V rails in FPGA carrier boards. IC Role / Device Role / Timing Role: Diodes 3 and 4 isolate enable signals with OR-ing logic while blocking backfeed between regulators. Use Value: Dual-anode/cathode pin 3 allows shared terminal routing; 70 mA IF rating supports 10 mA sequencing current with margin. |
Use Scenario: Providing temperature-stable bias to GaAs FET detectors in 2.4 GHz ISM band receivers. IC Role / Device Role / Timing Role: Diode 4 supplies regulated 0.75 V bias (VF = 750 mV @ 10 mA) to detector drain node. Use Value: VF variation <±20 mV from −40 °C to 125 °C ensures consistent detector sensitivity across environmental range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-40TR | Higher VF (550 mV @ 1 mA), larger SOT-23-6 package (3.0 × 1.75 mm), 40 V VR rating | Limited to ≤36 V systems; unsuitable for 48 V industrial clamping | Select only for cost-sensitive 5 V/12 V consumer electronics where 70 V rating is unnecessary |
| CMKD7004 TR PBFREE | Same SOT363-3 footprint but 30 V VR, 1000 h moisture sensitivity level (MSL 1), no specified Cd value | Requires redesign for >30 V applications; lacks documented capacitance for RF use | Prefer for automotive infotainment head units needing AEC-Q200 qualification (not offered by BAS70XY) |
Compared with RB050M-40TR and CMKD7004, the BAS70XY uniquely balances 70 V robustness, 2 pF RF suitability, and SOT363-3 miniaturization - making it optimal for space-constrained industrial power monitors and high-frequency signal clamps where both voltage margin and bandwidth matter.

FAQ
What is the maximum continuous forward current rating for BAS70XY?
The BAS70XY has a maximum continuous forward current (IF) of 70 mA per diode, validated under ambient conditions up to 150 °C. This rating assumes PCB thermal relief on pins 2, 3, 5, and 6 to maintain junction temperature ≤150 °C. Derating is required above 85 °C ambient per the thermal resistance of 260 K/W.
Can BAS70XY be used in place of BAS70-04 in existing designs?
No - BAS70-04 uses SOT323-4 (SC-70) package with 4 pins and different pinout, while BAS70XY is a 6-pin SOT363-3 device with quadruple topology and shared terminals. Direct replacement would require PCB layout revision and signal routing changes due to incompatible pin mapping and package dimensions.
Does BAS70XY meet RoHS and REACH compliance requirements?
Yes - BAS70XY is manufactured by Nexperia to full RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 compliance, with lead-free matte tin termination and halogen-free molding compound. Certificate of Compliance is available upon request from Aetrix Electronics with batch traceability.
What is the typical reverse recovery time (trr) for BAS70XY?
The BAS70XY does not specify trr in its datasheet because Schottky diodes are majority-carrier devices with no minority-carrier storage delay. Its switching behavior is governed by junction capacitance (2 pF) and series resistance, enabling effective operation beyond 1 GHz - confirmed by typical forward voltage vs. current curves showing sub-ns transition characteristics.
