Product details
Overview
BAS70-06-HE3-18 from Vishay Semiconductors is a common-anode dual Schottky diode in SOT-23 package, rated for 70 V repetitive peak reverse voltage, 200 mA forward current, and 5 ns reverse recovery time. It features low forward voltage (410 mV at 1 mA), 2 pF junction capacitance, and AEC-Q101 qualification for automotive signal rectification and clamping.
For engineers reviewing the BAS70-06-HE3-18 datasheet, BAS70-06-HE3-18 pinout, BAS70-06-HE3-18 application, or BAS70-06-HE3-18 equivalent, this part supports high-speed switching in space-constrained automotive and industrial control circuits where low VF and fast trr are critical for efficiency and noise suppression.
Technical Context
The BAS70-06-HE3-18 integrates two Schottky diodes sharing a common anode terminal, enabling compact dual-path clamping or level-shifting in bidirectional signal conditioning. Its 70 V VRRM rating and 125 °C max junction temperature support operation in under-hood automotive environments.
With 1.5–2 pF diode capacitance at 0 V and 1 MHz, and 5 ns reverse recovery time under 10 mA IF/IR conditions, it minimizes switching losses and EMI in high-frequency DC-DC feedback paths and I/O protection networks.
Key Specifications

| VRRM | 70 V - Withstands up to 70 V reverse bias without breakdown, suitable for 48 V system transient clamping |
| IF | 200 mA continuous - Supports moderate-current signal path rectification without thermal derating at ambient ≤85 °C |
| trr | 5 ns - Enables clean switching in >100 MHz digital signal routing and RF detector applications |
| VF @ 1 mA | 410 mV - Reduces forward conduction loss in low-current bias networks and precision clamp circuits |
| CD @ 0 V | 1.5–2 pF - Limits capacitive loading on high-impedance sensor inputs and clock lines |
| IR @ 50 V | 20–100 nA - Ensures minimal leakage in battery-backed monitoring circuits over temperature |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAS70-06T1G | Same SOT-23 package, common-anode, but rated for 70 V VRRM and 200 mA IF; VF = 450 mV @ 1 mA (higher than BAS70-06-HE3-18) | Not AEC-Q101 qualified; intended for commercial-grade industrial use only | Select when automotive qualification is not required and slightly higher VF is acceptable |
| NSR0230HT1G | Single Schottky in SOD-123; 30 V VRRM, 200 mA IF, VF = 390 mV @ 1 mA; no dual configuration | Requires two devices and extra board area to replicate dual functionality; lacks common-anode topology | Choose only if lower VF is prioritized over integration and space savings |
Compared with SBAS70-06T1G and NSR0230HT1G, the BAS70-06-HE3-18 uniquely delivers AEC-Q101 compliance, true dual common-anode integration, and lowest VF (410 mV) among RoHS-compliant SOT-23 dual Schottkys-making it optimal for space- and reliability-critical automotive signal paths.
