Product details
Overview
BAS70-04 from Nexperia is a silicon Schottky diode in SOT23 package configured as a common-cathode dual diode, rated for 70 V reverse voltage, 70 mA forward current, and 250 mW total power dissipation at ≤48 °C case temperature. It serves high-speed switching, voltage clamping, and RF mixing functions in compact signal-path circuits.
For engineers reviewing the BAS70-04 datasheet, BAS70-04 pinout, BAS70-04 application, or BAS70-04 equivalent, key selection criteria include its 1.5 pF typical junction capacitance at 0 V, 705 mV typical forward voltage at 10 mA, 100 ps reverse recovery time, low series inductance (1.8 nH), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual common-cathode Schottky diode enables independent anode control with shared cathode connection, supporting bidirectional clamping or dual-path signal routing in space-constrained layouts. Its low VF and fast τrr support operation up to UHF frequencies in detector/mixer stages.
The device exhibits tight forward voltage matching (ΔVF ≤ 20 mV at 10 mA) across both diodes and maintains stable IR ≤ 0.1 µA at 50 V reverse bias, ensuring predictable leakage behavior in precision bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - Supports rail-to-rail clamping in 48 V and 36 V automotive supply domains. |
| Forward Current (IF) | 70 mA - Enables continuous DC biasing of small-signal transducers without thermal derating below 48 °C case temp. |
| Junction Capacitance (CT) | 1.5 pF typ. at 0 V, 1 MHz - Minimizes signal loading in 900 MHz ISM band receiver front-ends. |
| Forward Voltage (VF) | 705 mV typ. at 10 mA - Reduces conduction loss in low-voltage logic-level clamping circuits. |
| Reverse Recovery Time (τrr) | 100 ps - Ensures clean edge fidelity in >100 Mbps digital signal steering applications. |
| Thermal Resistance (RthJS) | 410 K/W - Requires careful PCB copper area design to sustain full IF at ambient >60 °C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | Single diode, 30 V VR, 200 mA IF, SOD-123 package | Lacks dual configuration and AEC-Q101 rating; higher IF but lower VR | Use only where single-diode function suffices and automotive qualification is not required. |
| Diodes Incorporated BAV99LT1G | Dual common-cathode, 70 V VR, 215 mA IF, SOT-23, no AEC-Q101 | Higher IF rating but unqualified for automotive; VF = 1.25 V typ. at 10 mA | Acceptable for industrial signal clamping where lower VF and automotive validation are noncritical. |
Compared with NSR0230HT1G and BAV99LT1G, BAS70-04 provides verified AEC-Q101 compliance, tighter VF matching, and optimized 1.5 pF CT for RF-sensitive designs-making it the preferred choice when dual-channel automotive-grade clamping is required.

FAQ
What is the maximum operating temperature for BAS70-04?
The junction temperature limit is 150 °C, but the device's power derating curve specifies a maximum case temperature of 48 °C to sustain full 70 mA forward current. Above this, IF must be reduced per the IF vs. TS graph in the datasheet, with thermal resistance RthJS = 410 K/W defining the slope.
Is BAS70-04 suitable for RF mixing applications?
Yes-its 1.5 pF typical junction capacitance at 0 V, 100 ps reverse recovery time, and low 1.8 nH series inductance make it suitable for passive mixing and detection up to 2.4 GHz. Measured performance in 868 MHz ASK demodulators confirms usable conversion efficiency with sub-1 µW input signals.
Does BAS70-04 have lead-free and RoHS-compliant packaging?
Yes-BAS70-04 is manufactured in Pb-free, RoHS-compliant SOT23 packages per EU Directive 2011/65/EU and meets JEDEC J-STD-609A Class 3 moisture sensitivity level, with standard reflow profile compatibility (peak 260 °C).
How does the common-cathode configuration affect circuit layout?
The shared cathode (Pin 2) must connect to the lowest-impedance ground reference point to prevent crosstalk between anode paths. Layout best practice requires symmetric trace lengths from Pins 1 and 3 to Pin 2 and avoids routing sensitive analog traces near the cathode net to maintain isolation between dual channels.
