Product details
Overview
BAS70-06-7 from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT23 package, rated for 70 V peak reverse voltage, 70 mA forward current, and 410 mV max forward voltage at 1.0 mA. It features a PN junction guard ring for transient and ESD protection, and is optimized for low-loss signal clamping and high-speed switching in space-constrained DC-DC converter feedback paths.
For engineers reviewing the BAS70-06-7 datasheet, BAS70-06-7 pinout, BAS70-06-7 application, or BAS70-06-7 equivalent, key selection criteria include its 5.0 ns reverse recovery time, 2.0 pF junction capacitance at 0 V, 100 nA max reverse leakage at 50 V, and compatibility with lead-free reflow profiles per J-STD-020 Level 1.
Technical Context
This Schottky diode uses a planar epitaxial construction with integrated PN guard ring to suppress edge breakdown and improve robustness against electrostatic discharge and voltage transients. Its low forward voltage enables efficient voltage clamping in precision analog signal paths and fast flyback recovery in synchronous rectifier auxiliary windings.
The device operates across –55 °C to +125 °C junction temperature range and exhibits stable reverse leakage (<100 nA at 50 V) and capacitance (2.0 pF at 0 V, 1 MHz), making it suitable for high-frequency detector and RF sampling applications where parasitic effects must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 70 V - Maximum blocking voltage before avalanche onset; defines safe operating range in clamp and OR-ing circuits. |
| IF (mA) | 70 mA - Continuous forward current rating; sets thermal limit for sustained conduction in bias networks. |
| VF MAX (V) | 0.41 V @ 1.0 mA - Low conduction loss enables minimal voltage drop in signal-level rectification and level shifting. |
| tRR (ns) | 5.0 ns - Fast recovery supports >100 MHz switching in RF detectors and pulse shaping circuits. |
| CT (pF) | 2.0 pF @ 0 V - Low junction capacitance preserves bandwidth in high-frequency AC coupling and sampling applications. |
| IR MAX (nA) | 100 nA @ 50 V - Ultra-low leakage maintains accuracy in high-impedance sensor interfaces and reference voltage dividers. |
| RθJA (°C/W) | 625 °C/W - Thermal resistance on FR-4 board informs derating above 25 °C ambient for reliable long-term operation. |
Pinout & Package
Package: SOT23 - 3-pin surface-mount plastic package (2.9 mm × 1.3 mm × 1.0 mm), moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to lower-potential node in clamping or rectification; polarity marked by cathode band on top view. |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Connected to higher-potential node; serves as reference for voltage clamping and ESD protection path. |
| No Connect (Pin 3) | Internal die attach pad (non-functional) | Thermally conductive but electrically isolated; used for mechanical stability and heat dissipation in SOT23 layout. |
Key Features
| Feature | Design Value |
|---|---|
| PN Junction Guard Ring | Suppresses edge breakdown under transient stress, enabling reliable ESD immunity per IEC 61000-4-2 Level 4 (±8 kV contact). |
| Low Forward Voltage | 410 mV max at 1.0 mA ensures <1% error in precision voltage reference clamping at microamp bias currents. |
| Fast Switching Speed | 5.0 ns reverse recovery supports clean pulse edge fidelity in 100+ MHz RF envelope detection. |
| Green Compliance | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets automotive and industrial environmental mandates. |
Applications
| High-Speed Signal Clamping | Precision Reference Protection |
|---|---|
Use Scenario: Limiting input voltage swing of op-amp or ADC inputs to prevent rail-to-rail overvoltage damage. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed between signal line and reference rail. Use Value: 0.41 V forward drop and 5.0 ns recovery preserve signal integrity up to 50 MHz without introducing distortion or delay skew. | Use Scenario: Protecting voltage reference outputs (e.g., REF3025) from back-drive or ESD events during hot-plug connection. IC Role / Device Role / Timing Role: Reverse-biased shunt protector tied between reference output and ground. Use Value: 100 nA leakage at 50 V avoids loading errors in sub-1 µA reference output stages while guarding against ±8 kV ESD. |
| DC-DC Converter Feedback Snubbing | RF Detector Diode |
Use Scenario: Damping high-frequency ringing on optocoupler feedback lines in isolated flyback converters. IC Role / Device Role / Timing Role: Low-capacitance snubber diode placed across feedback resistor divider. Use Value: 2.0 pF junction capacitance minimizes phase shift in control loop compensation while clamping spikes below 70 V. | Use Scenario: Demodulating AM signals in UHF receiver front-ends (e.g., 433 MHz ISM band). IC Role / Device Role / Timing Role: Zero-bias envelope detector diode in passive peak-detect circuit. Use Value: Sub-500 mV turn-on and 5.0 ns tRR enable accurate amplitude tracking of modulated carriers with <1 dB insertion loss at 433 MHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky barrier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | 30 V VR, 200 mA IF, 0.33 V VF @ 10 mA - lower voltage rating but higher current capability. | Suitable for 3.3 V–5 V logic-level clamping; not recommended for 48 V bus monitoring or 50 V feedback snubbing. | Select when forward current exceeds 70 mA and reverse voltage stays ≤30 V; verify thermal margin at 200 mA. |
| BAT54C-7-F | Dual common-cathode configuration, 30 V VR, 0.24 V VF @ 10 mA - lower VF but reduced voltage headroom and dual-diode topology. | Optimized for dual-rail clamping or USB data line protection; requires redesign for single-diode placement. | Choose for space-constrained dual-signal protection; avoid if single-anode/single-cathode topology is fixed in PCB layout. |
Compared with RB520S-30T1G and BAT54C-7-F, the BAS70-06-7 uniquely balances 70 V blocking, ultra-low leakage, and SOT23 footprint-making it preferred for high-voltage, low-current precision analog protection where voltage headroom and signal fidelity are critical.

FAQ
What is the maximum reverse voltage rating for BAS70-06-7?
The BAS70-06-7 has a peak repetitive reverse voltage (VRRM) of 70 V, verified per DS11007 Rev. 27. This rating applies at TA = +25°C and defines the absolute maximum DC or sinusoidal peak reverse voltage the device can block without breakdown. Derating is required above 25°C ambient per the published power derating curve.
Is BAS70-06-7 RoHS and halogen-free compliant?
Yes. BAS70-06-7 is fully RoHS 3 compliant (2015/863/EU) with no purposely added lead, and classified as "Green" per Diodes' definition: <900 ppm bromine, <900 ppm chlorine, and <1000 ppm antimony compounds. This is confirmed in the datasheet notes and Diodes' official Green Product Definitions page.
Does BAS70-06-7 have automotive qualification?
No. Unlike the BAS70-04Q variant, the BAS70-06-7 is not AEC-Q101 qualified and is not manufactured in IATF 16949 certified facilities. It is intended for industrial, computing, and consumer applications. For automotive use, BAS70-04Q-7-F is the designated qualified version.
What is the thermal resistance junction-to-ambient for BAS70-06-7?
The thermal resistance junction-to-ambient (RθJA) is 625 °C/W when mounted on an FR-4 board using Diodes' recommended pad layout. This value assumes standard JEDEC test conditions and is used to calculate junction temperature rise under steady-state power dissipation (PD = 200 mW max).
