Product details
Overview
BAS70W-06Q-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT323 package, rated for 70 V peak repetitive reverse voltage, 70 mA forward current, and 0.41 V max forward voltage at 1 mA. It delivers fast 5.0 ns reverse recovery time and ultra-low 100 nA reverse leakage at 50 V, enabling use in high-efficiency DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the BAS70W-06Q-7-F datasheet, BAS70W-06Q-7-F pinout, BAS70W-06Q-7-F application, or BAS70W-06Q-7-F equivalent, key selection criteria include low VF for minimal conduction loss, AEC-Q101 qualification for automotive reliability, SOT323 footprint compatibility, and sub-2 pF junction capacitance for high-frequency switching integrity.
Technical Context
This Schottky diode uses a planar epitaxial structure with PN junction guard ring to suppress transient-induced failure and improve ESD robustness. Its low 0.41 V forward voltage threshold enables efficient operation in low-voltage, high-current paths where silicon diodes would incur excessive power loss.
The device exhibits 2.0 pF total capacitance at 0 V bias and 5.0 ns reverse recovery time under standardized 10 mA → 1 mA switching conditions, supporting stable performance in MHz-range switching regulators and freewheeling applications without oscillation or ringing.

Applications
| SMPS Freewheeling Diode | Reverse Polarity Protection |
|---|---|
Use Scenario: Placed across synchronous buck converter's low-side FET to clamp inductive kickback during dead-time. IC Role / Device Role / Timing Role: Fast-recovery Schottky clamping diode absorbing energy from output inductor during FET off-cycle. Use Value: 5.0 ns tRR prevents reverse recovery oscillation; 0.41 V VF reduces conduction loss by ~35% vs. standard silicon diode at 1 mA. | Use Scenario: Installed in series with VIN rail to block reverse-connected batteries or adapters in portable electronics. IC Role / Device Role / Timing Role: Unidirectional current gate protecting downstream PMICs and microcontrollers from negative voltage damage. Use Value: 100 nA IR ensures <1 µW standby power loss; 70 V VRRM supports 24–48 V industrial input ranges. |
| DC-DC Converter Output Rectifier | Blocking Diode in Sensor Interface |
Use Scenario: Used as secondary-side rectifier in isolated flyback or forward converter powering FPGA core rails. IC Role / Device Role / Timing Role: High-frequency rectifying element converting transformer AC output to regulated DC, operating at 500 kHz–1 MHz. Use Value: 2.0 pF CT minimizes switching node ringing; SOT323 thermal resistance allows 70 mA continuous current without derating below +85°C. | Use Scenario: Isolates analog sensor supply from shared MCU VDD rail to prevent noise coupling in precision measurement systems. IC Role / Device Role / Timing Role: Low-leakage blocking diode decoupling sensor bias path from digital switching transients. Use Value: 100 nA IR avoids offset drift in µA-level sensor bias currents; 0.41 V VF maintains >98% voltage delivery at 100 µA load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T2R | 30 V VRRM, 200 mA IO, 0.33 V VF @ 10 mA - lower voltage rating but higher current capacity | Not suitable for 48 V systems; better for 3.3–12 V consumer DC-DC outputs | Select when IO > 100 mA required and reverse voltage ≤30 V |
| NSR0230HT1G | 30 V VRRM, 200 mA IO, 0.32 V VF @ 10 mA, SOD-523 package - smaller footprint, same voltage limit | Limited to ≤30 V rails; not AEC-Q101 qualified | Choose for space-constrained non-automotive designs needing lowest VF |
Compared with RB520S-30T2R and NSR02030HT1G, BAS70W-06Q-7-F uniquely balances 70 V blocking, AEC-Q101 compliance, and SOT323 manufacturability-making it the only option among the three qualified for 48 V automotive body electronics and industrial power modules.

FAQ
What is the maximum junction temperature for continuous operation?
The BAS70W-06Q-7-F has a specified operating junction temperature range of –55 °C to +125 °C. Under typical FR-4 PCB mounting (1″ × 0.85″, per Note 6), its 200 mW power dissipation rating allows full 70 mA forward current up to +85 °C ambient. Derating begins above that point per the published power derating curve (Fig. 4).
Is this diode suitable for automotive applications?
Yes. The BAS70W-06Q-7-F is explicitly qualified to AEC-Q101 standards and PPAP-capable. Its construction includes a PN junction guard ring for ESD/EMI resilience, halogen-free green packaging, and validated performance across –40 °C to +125 °C ambient-meeting requirements for body control modules, infotainment power supplies, and ADAS sensor interfaces.
How does the SOT323 package affect thermal performance?
The SOT323 package provides a thermal resistance of 625 °C/W (junction-to-ambient). While compact, its exposed metal slug (Pin 3) is electrically isolated and functions solely as a thermal path. Effective heat transfer requires a minimum 10 mm² copper pour connected to Pin 3 via multiple vias to internal ground planes-otherwise, power derating is necessary above +60 °C ambient.
What is the significance of the "-06Q" suffix in the part number?
The "-06Q" suffix identifies the specific variant within the BAS70WQ family, indicating a 70 V VRRM rating and AEC-Q101 qualification. It distinguishes this part from -04Q (40 V), -05Q (50 V), and base BAS70WQ (unspecified voltage grade), ensuring correct selection for 48 V system-level blocking and freewheeling roles.
