Product details
Overview
BAS70-05Q-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT23 package, rated for 70 V reverse voltage, 70 mA continuous forward current, and 0.41 V max forward voltage at 1.0 mA - optimized for low-loss signal clamping and high-speed switching in automotive sensor interfaces and USB port protection circuits.
For engineers reviewing the BAS70-05Q-7-F datasheet, BAS70-05Q-7-F pinout, BAS70-05Q-7-F application, or BAS70-05Q-7-F equivalent, key selection criteria include its AEC-Q101 qualification, 2.5 ns reverse recovery time, 1.7 pF junction capacitance at 0 V, and PN-junction guard ring for ESD robustness in space-constrained automotive modules.
Technical Context
This Schottky diode employs a planar epitaxial structure with integrated PN junction guard ring to suppress edge breakdown and enhance transient immunity. Its low 0.41 V forward voltage at 1 mA enables efficient voltage clamping in 3.3 V and 5 V logic rails without excessive power loss.
The device operates across –55 °C to +125 °C and exhibits 100 nA max reverse leakage at 50 V, supporting stable performance in engine control units and infotainment power management where thermal drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 70 V - maximum DC blocking capability for 24 V automotive systems with load-dump margin |
| IF (mA) | 70 mA - continuous forward current rating suitable for signal-level protection, not power rectification |
| VF MAX (V) | 0.41 V @ 1.0 mA - enables low-voltage signal clamping with minimal forward drop in I²C/SPI lines |
| tRR (ns) | 2.5 ns - supports >100 MHz signal integrity in high-speed data line protection |
| CT (pF) | 1.7 pF @ 0 V - preserves bandwidth in RF-coupled sensor front-ends and USB 2.0 signal paths |
| IR MAX (nA) | 100 nA @ 50 V - ensures negligible leakage in battery-backed monitoring circuits |
| TJ Range | –55 °C to +125 °C - qualified for under-hood automotive environments per AEC-Q101 |
Pinout & Package
Package: SOT23 - surface-mount plastic case (UL 94V-0), 0.008 g mass, 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 protected signal line or supply rail; polarity marked by cathode band on package top view |
| Cathode (Pin 2) | Forward current exit / reverse blocking node | Typically tied to ground or lower-potential rail; forms clamp path during overvoltage transients |
| No-Connect (Pin 3) | Internal die pad, electrically isolated | Thermally conductive but unconnected; used for mechanical stability and heat dissipation in FR-4 layout |
Key Features
| Feature | Design Value |
|---|---|
| PN junction guard ring | Suppresses edge breakdown during ESD events (IEC 61000-4-2 Level 4), enabling standalone port protection without external TVS |
| AEC-Q101 qualification | Validated for automotive applications including body control modules and ADAS sensor interfaces |
| Lead-free & halogen-free | Complies with RoHS 3 (2015/863/EU) and "Green" definition (<900 ppm Br+Cl, <1000 ppm Sb) |
| Low RθJA (600 °C/W) | Enables 200 mW power dissipation on standard FR-4 with recommended pad layout (X=0.8 mm, Y=0.9 mm) |
Applications
| Automotive Sensor Interface | USB 2.0 Port Protection |
|---|---|
Use Scenario: Clamping induced transients on LIN bus or analog sensor outputs in engine control units. IC Role / Device Role / Timing Role: Signal-level Schottky clamp diode placed between sensor output and microcontroller input. Use Value: 2.5 ns tRR and 1.7 pF CT preserve signal fidelity up to 10 MHz while suppressing ±30 kV ESD pulses via guard ring. | Use Scenario: Protecting D+ and D− lines of automotive infotainment USB ports from hot-plug surges and cable discharge events. IC Role / Device Role / Timing Role: Bidirectional low-capacitance clamp on differential data lines. Use Value: 0.41 V VF minimizes voltage offset on 3.3 V signaling; 100 nA IR prevents data-line bias shift during suspend mode. |
| Low-Voltage Logic Clamping | RF Detector Bias Network |
Use Scenario: Preventing overvoltage damage to GPIO pins of automotive MCUs operating at 1.8 V or 3.3 V. IC Role / Device Role / Timing Role: Anode-to-signal, cathode-to-rail clamp limiting excursion to VF above rail. Use Value: 70 V VR withstands load-dump-induced spikes; 70 mA IF handles brief fault currents without thermal runaway. | Use Scenario: Providing temperature-stable DC bias path in 2.4 GHz Wi-Fi antenna diversity switches. IC Role / Device Role / Timing Role: Low-Ct shunt element in detector feedback loop. Use Value: 1.7 pF CT remains stable from –40 °C to +85 °C; guard ring prevents RF-induced latch-up in high-GHz operation. |
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 (0.45 V @ 10 mA); same SOT23-3, AEC-Q101 qualified | Slightly higher conduction loss in low-current bias networks | Prefer when higher surge rating (IFSM = 600 mA) is required over ultra-low VF |
| BAT54C-7-F | Lower VR (30 V); dual common-cathode configuration; no AEC-Q101 qualification | Not suitable for 24 V automotive systems; limited to consumer-grade 5 V applications | Select only for cost-sensitive non-automotive designs where VR margin is not critical |
Compared with SBAT54LT1G and BAT54C-7-F, BAS70-05Q-7-F uniquely balances 70 V VR, 0.41 V VF at 1 mA, AEC-Q101 compliance, and guard-ring ESD hardening - making it optimal for safety-critical 12/24 V automotive signal conditioning where both voltage margin and signal integrity are constrained.

FAQ
What is the maximum reverse voltage rating for BAS70-05Q-7-F?
The maximum repetitive reverse voltage (VRRM) is 70 V, verified per DS41740 Rev. 2–2. This rating allows safe operation in 24 V automotive systems with full load-dump margin (ISO 7637-2 Pulse 5a), and is validated across the full –55 °C to +125 °C junction temperature range.
Is BAS70-05Q-7-F suitable for USB 2.0 data line protection?
Yes - its 1.7 pF junction capacitance at 0 V and 2.5 ns reverse recovery time meet USB 2.0 eye-diagram integrity requirements. The PN guard ring provides inherent IEC 61000-4-2 Level 4 ESD protection (±30 kV contact), eliminating need for additional TVS devices on D+/D− lines.
How does the PN junction guard ring improve reliability?
The integrated guard ring prevents premature edge breakdown during fast transients and ESD events by redistributing electric field stress away from the active junction periphery. This extends device lifetime under repeated 100 ns/1 kV surge conditions and improves failure rate in automotive environments per AEC-Q101 stress testing.
What is the thermal resistance of BAS70-05Q-7-F on standard FR-4?
RθJA is 600 °C/W when mounted on a standard FR-4 PCB using Diodes Incorporated's recommended SOT23 pad layout (X = 0.8 mm, Y = 0.9 mm). This value assumes natural convection and is measured per JESD51-2; derating follows the published power curve in DS41740 Figure 1.
