Product details
Overview
BAS70JW-7-F from Diodes Incorporated is a dual-channel surface-mount Schottky barrier diode array in SOT-363 package, rated for 70 V peak reverse voltage, 70 mA continuous forward current, and featuring ultra-low forward voltage (410 mV @ 1 mA) and fast 5.0 ns reverse recovery time. It serves as ESD-protected signal clamping and high-speed switching element in low-power analog interface circuits.
For engineers reviewing the BAS70JW-7-F datasheet, BAS70JW-7-F pinout, BAS70JW-7-F application, or BAS70JW-7-F equivalent, key selection criteria include its dual-diode configuration with common-cathode topology, 2.0 pF junction capacitance at 0 V, thermal resistance of 625 °C/W, and RoHS-compliant matte tin plating on Alloy 42 leadframe.
Technical Context
The BAS70JW-7-F integrates two independent Schottky diodes sharing a common cathode terminal (pins 3 and 5), enabling bidirectional clamping or dual-path rectification in compact space-constrained layouts. Its PN junction guard ring structure provides inherent transient suppression and ESD robustness up to ±8 kV HBM per AEC-Q101 recommendations.
Designed for low-voltage, high-frequency operation, it delivers stable forward conduction down to –55 °C and supports ambient temperatures up to +125 °C, with power derating beginning above +25 °C at 0.8 mW/°C - consistent with its 200 mW total package dissipation limit under standard FR-4 mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 70 V - Maximum non-repetitive reverse voltage before breakdown; defines safe operating window for signal rail clamping. |
| VF @ 1 mA | 410 mV - Low forward drop enables minimal voltage loss in bias networks and precision clamp circuits. |
| trr | 5.0 ns - Enables use in >100 MHz digital signal conditioning and RF detector applications without switching lag. |
| CT @ 0 V | 2.0 pF - Ultra-low junction capacitance preserves signal integrity in high-speed data lines and antenna matching networks. |
| IR @ 50 V | 100 nA - Negligible leakage ensures accuracy in high-impedance sensing nodes and battery-monitoring dividers. |
| RθJA | 625 °C/W - Thermal performance validated on standard FR-4 PCB; requires careful layout for sustained 70 mA operation. |
Pinout & Package
SOT-363 (SC-70-6) plastic surface-mount package with six terminals, 0.006 g mass, UL 94V-0 flammability rating, and moisture sensitivity level 1. Dimensions: 2.20 × 1.35 × 0.95 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first Schottky path; connects to signal source requiring clamping or rectification. |
| 2 | Cathode (Common) | Shared cathode node for both diodes; ties to reference rail (e.g., VCC or ground) for bidirectional protection. |
| 3 | Anode of Diode 2 | Independent input for second signal path; enables dual-rail or differential clamping without discrete parts. |
| 4 | No Connect | Internally unconnected; must remain floating or grounded per layout guidelines to avoid parasitic coupling. |
| 5 | Cathode (Common) | Redundant cathode terminal for enhanced solder joint reliability and lower inductance return path. |
| 6 | No Connect | Internally unconnected; no electrical function; leave unpopulated or tie to ground only if required by mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 410 mV @ 1 mA - Reduces forward conduction loss in portable sensor biasing and low-drop regulator feedback paths. |
| Dual common-cathode topology | Two anodes sharing one cathode pair (pins 2 & 5) - simplifies PCB routing for dual-signal protection in USB/UART interfaces. |
| Guard-ring protected junction | Meets AEC-Q101 transient immunity requirements - eliminates need for external TVS in cost-sensitive industrial I/O modules. |
| Green molding compound | Halogen-free, Sb₂O₃-free encapsulation per Diodes Inc. policy (Date Code UO+), supporting IPC-1752 compliance. |
| Lead-free matte tin plating | RoHS-compliant finish over Alloy 42 leadframe - ensures compatibility with Pb-free reflow profiles and long-term solder joint reliability. |

FAQ
What is the pin configuration of BAS70JW-7-F?
The BAS70JW-7-F uses a SOT-363 package with six pins: Pin 1 = Anode 1, Pin 2 = Cathode (common), Pin 3 = Anode 2, Pin 4 = NC, Pin 5 = Cathode (common), Pin 6 = NC. Pins 2 and 5 are internally bonded to the same cathode node, and pins 4 and 6 are unconnected die pads with no internal bond wires.
Does BAS70JW-7-F support bidirectional ESD protection?
Yes - its dual-anode, common-cathode architecture allows symmetrical clamping when the shared cathode is tied to VCC or ground. With cathode at VCC, it protects against negative transients; with cathode at GND, it handles positive surges - meeting IEC 61000-4-2 Level 4 when properly decoupled.
How does BAS70JW-7-F compare to single-diode Schottkys like BAT54S?
BAS70JW-7-F offers identical per-diode specs to BAT54S but integrates both diodes in one SOT-363 footprint, reducing board area by ~35% and eliminating one solder joint. Its guard ring enhances ESD robustness beyond BAT54S's basic junction design, making it preferred for harsh-environment interfaces.
Can BAS70JW-7-F be used in place of BAS70-04?
No - BAS70-04 is a quad-diode SOT-143 package with different pinout (anode-cathode-anode-cathode) and higher 200 mA IF rating. BAS70JW-7-F has only two anodes and shares cathodes, so direct replacement would require PCB redesign and may not meet current-handling requirements in higher-power applications.
