Product details
Overview
BAS70VY from Nexperia is a general-purpose triple Schottky diode in SOT363-3 (SC-88) package, electrically isolated with three independent anode-cathode pairs. It delivers 70 V reverse voltage rating, 70 mA forward current per diode, 410 mV forward voltage at 1 mA, 2 pF capacitance at 0 V, and supports ultra high-speed switching and voltage clamping in compact PCB designs.
For engineers reviewing the BAS70VY datasheet, BAS70VY pinout, BAS70VY application, or BAS70VY equivalent, this page provides verified electrical parameters, terminal mapping for TSSOP6 layout, thermal resistance data (Rth(j-a) = 520 K/W), and real-world use cases in signal integrity and protection circuits.
Technical Context
The BAS70VY integrates three discrete Schottky diodes in a single monolithic SOT363-3 package with fully isolated junctions-no shared cathodes or anodes. Each diode exhibits low forward voltage (≤750 mV at 10 mA), sub-100 nA reverse leakage at 50 V, and minimal junction capacitance (2 pF), enabling operation beyond 1 GHz in RF-sensitive clamping paths.
Its thermal design supports FR4 PCB mounting with Rth(j-sp) = 450 K/W to solder point and Rth(j-a) = 520 K/W in free air. The device operates across −55 °C to +150 °C ambient, with junction temperature limited to 150 °C and peak non-repetitive surge current rated at 1.2 A (10 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - Enables clamping of transient spikes up to 70 V without breakdown in 3.3 V/5 V logic rails. |
| Forward Voltage (VF) | 410 mV @ 1 mA - Reduces conduction loss and self-heating in low-current bias and sensing paths. |
| Reverse Current (IR) | 100 nA @ 50 V - Ensures minimal leakage-induced offset in precision analog front-ends. |
| Capacitance (Cd) | 2 pF @ 0 V - Preserves signal edge integrity in >500 MHz digital or RF interface lines. |
| Thermal Resistance (Rth(j-a)) | 520 K/W - Requires careful copper pour planning on FR4 for sustained 70 mA per diode operation. |
| Peak Surge Current (IFSM) | 1.2 A @ 10 ms - Handles ESD-like transients without permanent degradation. |
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 transparent top view and pin 1 index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | Anode of Diode 1 - Connects to positive side of first clamping path; isolated from other anodes. |
| 2 | A2 | Anode of Diode 2 - Independent input node for second signal line or rail clamp. |
| 3 | A3 | Anode of Diode 3 - Enables three-channel bidirectional protection without cross-talk. |
| 4 | K3 | Cathode of Diode 3 - Shared cathode routing not supported; each cathode must be individually terminated. |
| 5 | K2 | Cathode of Diode 2 - Required for separate return paths to avoid ground bounce coupling. |
| 6 | K1 | Cathode of Diode 1 - Supports star-grounding schemes in mixed-signal PCB layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Triple isolated Schottky structure | Three independent diodes in one footprint - eliminates inter-diode leakage coupling and enables multi-rail clamping without shared nodes. |
| Low forward voltage (410 mV) | Minimizes power loss and voltage drop in low-voltage I/O protection (e.g., USB 2.0, LVDS, GPIO). |
| Ultra-low capacitance (2 pF) | Preserves rise/fall times in high-speed digital interfaces up to 1 Gbps without signal distortion. |
| High reverse breakdown (70 V) | Supports robust ESD and surge protection in industrial control inputs and sensor interfaces. |
Applications
| USB 2.0 Data Line Protection | LVDS Receiver Clamp |
|---|---|
Use Scenario: Protecting D+ and D− lines against ±8 kV contact ESD per IEC 61000-4-2 while maintaining signal fidelity. IC Role / Device Role: Bidirectional clamping diode array placed between connector and transceiver IC. Use Value: 2 pF capacitance prevents signal degradation at 480 Mbps; 70 V VR withstands common-mode surges on unshielded cables. | Use Scenario: Clamping differential inputs of LVDS receivers exposed to board-level noise and crosstalk. IC Role / Device Role: Low-capacitance shunt element tied to termination voltage (VTT) on both sides of differential pair. Use Value: Isolated anodes allow independent clamping of each line; 410 mV VF ensures fast turn-on before receiver damage threshold. |
| Industrial Sensor Signal Conditioning | Microcontroller GPIO Protection |
Use Scenario: Shielding analog sensor outputs (e.g., thermocouple, RTD) from induced transients in factory-floor wiring. IC Role / Device Role: Rail-to-rail clamping diode connected between signal line and supply/ground rails. Use Value: 100 nA IR at 50 V avoids loading high-impedance sensor sources; 150 °C max Tj supports operation near motors or drives. | Use Scenario: Safeguarding 3.3 V microcontroller pins against accidental 12 V miswiring or relay coil kickback. IC Role / Device Role: Anode-to-pin, cathode-to-VCC configuration for overvoltage clamping; cathode-to-ground for negative excursion limiting. Use Value: Triple configuration allows simultaneous protection of multiple GPIOs with shared footprint; 1.2 A IFSM absorbs inductive energy without failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | Single-channel dual-Schottky in SOT23-6; no electrical isolation between diodes. | Limited to two-diode configurations; unsuitable for three-rail independent clamping. | Select only when footprint compatibility and dual-diode function suffice. |
| BAT54CW | Triple Schottky in SOT323; higher VF (≈450 mV), higher Cd (≈10 pF), same VR (70 V). | Lower speed and higher loading limit use in >100 Mbps interfaces. | Prefer for cost-sensitive, lower-frequency applications where 2 pF is not critical. |
Compared with DMN3026LSD-13 and BAT54CW, the BAS70VY uniquely combines full electrical isolation, 2 pF capacitance, and 410 mV VF in SOT363-3-making it optimal for high-density, multi-rail ESD protection where signal integrity and channel independence are mandatory.

FAQ
Is BAS70VY suitable for automotive applications?
No. The BAS70VY is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or PPAP documentation. Nexperia explicitly states non-automotive qualification in its legal disclaimers, and the device is intended for industrial, computing, and consumer equipment only.
Can BAS70VY replace BAT54 series diodes in existing designs?
Yes, with layout adaptation. BAS70VY shares identical VR (70 V) and IF (70 mA) ratings but uses SOT363-3 instead of SOT323. Its lower capacitance (2 pF vs. ~10 pF) and isolated structure improve performance, but pinout differs-requiring PCB revision to match A1–A3/K1–K3 mapping.
What is the maximum continuous forward current per diode?
The maximum continuous forward current per diode is 70 mA under standard FR4 PCB mounting conditions (single-sided copper, tin-plated). This rating assumes Tamb = 25 °C and accounts for thermal resistance of 520 K/W; derating is required above 25 °C ambient or with reduced copper area.
Does BAS70VY support reflow soldering?
Yes. Nexperia provides validated reflow soldering footprints for SOT363-3 in its datasheet (Figure 6), specifying 2.65 mm × 2.35 mm solder land dimensions, 0.4 mm solder resist openings, and compatible stencil paste volume. Peak reflow temperature must not exceed 260 °C per JEDEC J-STD-020.
