Product details
Overview
BAS70-06T-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT523 package, rated for 70 V peak repetitive reverse voltage, 70 mA forward current, and 5.0 ns reverse recovery time. It features low forward voltage (410–1000 mV at 1–15 mA), ultra-low junction capacitance (2.0 pF at 0 V), and PN junction guard ring for ESD/transient protection-used in high-speed signal clamping and RF detector circuits.
For engineers reviewing the BAS70-06T-7-F datasheet, BAS70-06T-7-F pinout, BAS70-06T-7-F application, or BAS70-06T-7-F equivalent, key selection criteria include reverse voltage rating, switching speed, junction capacitance, thermal resistance (833 °C/W), and SOT523 footprint compatibility with space-constrained PCB layouts.
Technical Context
This Schottky diode uses a planar epitaxial construction with a PN junction guard ring to suppress edge breakdown and improve transient robustness. Its low barrier height enables fast carrier injection/extraction, yielding sub-5 ns reverse recovery time under 10 mA switching conditions.
The device operates across –55 °C to +125 °C and exhibits stable leakage (<100 nA at 50 V) and capacitance (≤2.0 pF at 0 V) over temperature-critical for precision RF envelope detection and high-frequency sampling applications where parasitic capacitance and charge storage must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 70 V - maximum blocking voltage before avalanche; sets upper limit for signal swing in clamp/detector circuits |
| IF | 70 mA - continuous forward current rating; defines max DC bias in low-power rectification paths |
| trr | 5.0 ns - measured at 10 mA → 1 mA transition; enables operation up to ~70 MHz in sampling applications |
| CT | 2.0 pF at 0 V - low junction capacitance minimizes loading on RF nodes and preserves bandwidth |
| VF | 410–1000 mV - forward drop at 1–15 mA; balances conduction loss vs. sensitivity in detector designs |
| RθJA | 833 °C/W - thermal resistance on FR-4 board; limits power dissipation to ≤150 mW at ambient |
Pinout & Package
Package: SOT523 - ultra-small plastic surface-mount package (1.60 × 1.60 × 0.75 mm), lead-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node in clamping or rectification path; polarity marked by dot on top view |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Typically tied to ground or reference rail; forms low-capacitance return path in RF detectors |
| Case / Exposed Pad (Pin 3) | Non-electrical mechanical tie | No internal connection; serves only as mechanical anchor and thermal mass-must not be electrically biased |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 410 mV @ 1 mA enables high-sensitivity RF detection with minimal signal loss |
| Fast switching | 5.0 ns trr supports >50 MHz signal sampling without distortion or tailing |
| Guard ring protection | Integrated PN junction ring suppresses edge leakage and improves ESD robustness (HBM >8 kV typical) |
| Ultra-small footprint | SOT523 package occupies <2.6 mm² PCB area-ideal for wearables and miniaturized IoT sensors |
Applications
| RF Signal Detector | High-Speed Logic Clamp |
|---|---|
Use Scenario: Demodulating AM signals in sub-GHz ISM band receivers (e.g., 315/433 MHz remote controls). IC Role / Device Role / Timing Role: Schottky detector diode converting RF envelope to baseband voltage; operates in zero-bias or low-bias mode. Use Value: 2.0 pF capacitance and 5.0 ns trr preserve modulation fidelity; 410 mV VF ensures usable output at microamp input levels. | Use Scenario: Protecting CMOS inputs from overshoot during hot-plug or bus contention in USB 2.0 data lines. IC Role / Device Role / Timing Role: Bidirectional clamping diode shunting transients above VDD or below GND. Use Value: Guard ring structure withstands >8 kV HBM ESD; low CT avoids signal edge degradation at 480 Mbps. |
| Low-Power Voltage Reference | Sample-and-Hold Input Stage |
Use Scenario: Generating stable bias points in battery-powered sensor front-ends using self-biased Schottky drop. IC Role / Device Role / Timing Role: Forward-biased diode providing ~0.4 V reference offset with temperature tracking. Use Value: Tight VF tolerance (410–1000 mV) and –55 to +125 °C operation enable drift-compensated references. | Use Scenario: Front-end protection and signal conditioning in 12-bit SAR ADC sample circuits. IC Role / Device Role / Timing Role: Fast-recovery clamp limiting input voltage during acquisition phase. Use Value: 5.0 ns trr prevents hold-mode corruption; 70 V VRRM accommodates ±15 V analog rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Lower VRRM (30 V), higher IF (200 mA), same SOT-23 package | Not suitable for 50+ V clamping; better for 3.3 V logic rail protection | Select when higher forward current and lower cost are prioritized over voltage rating |
| RB520S-30T2R | Higher VRRM (30 V), lower CT (1.5 pF), SOD-523 package (same footprint) | Marginally faster but lower voltage rating; identical mounting | Choose for ultra-low-capacitance needs in 2.4 GHz BLE receiver front-ends |
Compared with NSR0230HT1G and RB520S-30T2R, BAS70-06T-7-F uniquely balances 70 V blocking, 5 ns speed, and 2.0 pF capacitance in SOT523-making it optimal for mixed-signal clamping where voltage headroom and RF integrity are both critical.

FAQ
Is BAS70-06T-7-F suitable for automotive applications?
No-BAS70-06T-7-F is not AEC-Q101 qualified. While it operates from –55 °C to +125 °C, Diodes explicitly states that automotive-grade versions require separate qualification (PPAP, IATF 16949 manufacturing) and are designated with distinct part numbers. This variant is intended for commercial and industrial use only.
What is the polarity marking for BAS70-06T-7-F?
The cathode is marked by a color band or dot adjacent to Pin 2 on the top surface of the SOT523 package. Per Diodes' datasheet DS30261 Rev. 12, the marking code "7F" identifies BAS70-06T, and polarity follows standard SOT523 orientation: Pin 1 (anode) is leftmost when the marking is read left-to-right with the tab facing up.
Can BAS70-06T-7-F replace BAS70-05T-7-F in existing designs?
Yes-both share identical SOT523 package, pinout, and thermal characteristics. The only difference is reverse voltage rating: BAS70-05T is rated for 50 V VRRM, while BAS70-06T is rated for 70 V. Substitution is safe if the circuit's maximum reverse voltage does not exceed 50 V; otherwise, BAS70-06T provides additional margin.
Does BAS70-06T-7-F have an exposed thermal pad?
No-the SOT523 package has no exposed thermal pad. Pin 3 is a non-electrical case tie with no internal connection. Thermal performance relies solely on conduction through the leads and PCB copper; the recommended pad layout (from Diodes' package outline document) uses standard solder mask-defined pads without thermal vias or metal slugs.
