Product details
Overview
BAS70W-06-7 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 5.0 ns reverse recovery time. It features low forward voltage (410 mV @ 1 mA), ultra-low capacitance (2.0 pF @ 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 BAS70W-06-7 datasheet, BAS70W-06-7 pinout, BAS70W-06-7 application, or BAS70W-06-7 equivalent, key selection criteria include reverse breakdown voltage (70 V), fast switching performance (trr ≤ 5.0 ns), low VF at low IF, thermal derating behavior (625 °C/W RθJA), and SOT323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This Schottky diode uses a platinum-silicide (PtSi) or similar low-barrier metal-semiconductor junction to achieve low forward voltage and fast minority-carrier-free switching. Its guard-ringed structure suppresses edge leakage and improves transient robustness without compromising speed.
The device operates across –55 °C to +125 °C and is characterized under pulsed conditions (tp < 300 µs) to minimize self-heating effects-ensuring stable VF and IR specifications in real-world signal-path applications like envelope detection and logic-level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 70 V - maximum allowable repetitive reverse voltage before breakdown; sets safe operating limit in clamp/protection circuits |
| VF @ 1 mA | 410 mV - enables efficient low-current signal rectification with minimal voltage loss in RF detector stages |
| trr | 5.0 ns - supports >100 MHz switching in high-frequency sampling and pulse shaping applications |
| CT @ 0 V | 2.0 pF - minimizes capacitive loading on high-impedance nodes in RF front-ends and precision analog signal paths |
| RθJA | 625 °C/W - defines thermal derating slope on standard FR-4 PCB; requires layout-aware power management above ~50 mW |
| IR @ 50 V | 100 nA - ensures negligible leakage in battery-powered sensor bias networks and high-Z sample-hold circuits |
Pinout & Package
Package: SOT323 - ultra-small plastic surface-mount package (2.0 × 2.225 × 0.9 mm), moisture sensitivity level 1, matte tin-plated leads, weight ≈ 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to lower-potential node in clamping or rectifying path; polarity marked by cathode band on package top view |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Connected to higher-potential rail or signal reference; carries full reverse voltage during off-state |
| Collector/Case (Pin 3) | Thermal and mechanical tie | Non-electrical; internal die attach pad tied to leadframe; no circuit function but critical for thermal conduction and solder joint reliability |
Key Features
| Feature | Design Value |
|---|---|

Use Value: 410 mV VF minimizes forward drop in low-voltage (1.8–3.3 V) battery systems, preserving dynamic range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Higher VF (460 mV @ 1 mA); same SOT-23 package; 100 V VRRM | Better suited for higher-voltage clamping; less optimal for ultra-low-VF detector designs | Select when system reverse voltage exceeds 70 V but space constraints match SOT-23 |
| NSR0230HT1G | Lower VF (275 mV @ 10 mA); SOD-523 package; 30 V VRRM | Optimized for low-voltage (<3.3 V) logic protection; insufficient for 50 V+ signal paths | Choose only where reverse voltage stays below 30 V and minimal VF dominates design priority |
Compared with SBAT54LT1G and NSR0230HT1G, BAS70W-06-7 uniquely balances 70 V blocking, sub-420 mV VF at microamp bias, and 2.0 pF capacitance-making it optimal for RF detector and medium-voltage clamping where all three parameters are simultaneously constrained.

FAQ
What is the maximum continuous forward current rating for BAS70W-06-7?
The maximum continuous forward current (IF) is 70 mA at TA = +25°C. Derating applies above ambient temperatures per the published power derating curve: PD drops linearly to zero at +125°C, governed by RθJA = 625 °C/W on standard FR-4 PCB layout.
Does BAS70W-06-7 have automotive-grade qualification?
No-BAS70W-06-7 is an industrial-grade part. The automotive-compliant variant is BAS70WQ-06Q, qualified to AEC-Q101 and documented in a separate datasheet (DS30113Q). This part lacks PPAP documentation and extended temperature validation beyond –55°C to +125°C.
How is polarity identified on the SOT323 package of BAS70W-06-7?
Polarity is marked by a cathode band on the top surface of the SOT323 package, aligned with Pin 2 (cathode). The standard top-view orientation shows Pin 1 (anode) at the bottom-left corner, Pin 2 (cathode) at bottom-right, and Pin 3 (case) at top-center-matching Diodes' official package outline DS30113 Rev. 14.
Can BAS70W-06-7 be used in place of BAS70W-04 or BAS70W-05?
Yes-BAS70W-04, -05, and -06 share identical SOT323 package, thermal specs, and electrical characteristics except for marking codes. All three are electrically identical per DS30113; the suffix denotes date-code and traceability variants, not functional differentiation.
