Product details
Overview
BAS7004TC from Nexperia is a dual common-cathode Schottky barrier diode in SOT23 package, rated for 70 V reverse voltage, 15 mA forward current, and 410 mV forward voltage at 1 mA - used in high-speed signal clamping and RF detector circuits in portable communications equipment.
For engineers reviewing the BAS7004TC datasheet, BAS7004TC pinout, BAS7004TC application, or BAS7004TC equivalent, key selection criteria include low forward voltage for battery-sensitive biasing, sub-2 pF junction capacitance for >50 MHz operation, and dual-common-cathode configuration for compact dual-path signal routing.
Technical Context
This dual Schottky diode integrates two independent anodes sharing a single cathode terminal, enabling synchronous clamping or envelope detection without inter-device mismatch. Its 100 ps minority carrier lifetime supports switching speeds suitable for VHF/UHF receiver front-ends.
Designed with planar silicon process, it achieves stable reverse leakage (≤200 nA at 50 V) and tight VF matching between channels - critical for balanced detector topologies and low-distortion sampling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VBR) | 70 V minimum - ensures safe operation in 48 V telecom line interface and 50 V RF bias rails |
| Forward Voltage (VF) | 410 mV at 1 mA - minimizes power loss and thermal rise in battery-powered detector stages |
| Junction Capacitance (CT) | 2.0 pF at 1 MHz, 0 V - enables use up to 500 MHz in small-signal RF coupling paths |
| Reverse Leakage (IR) | 200 nA max at 50 V - preserves signal integrity in high-impedance sample-and-hold nodes |
| Forward Current (IF) | 15 mA continuous - supports moderate-current biasing of mixer LO ports and AGC control paths |
| Minority Lifetime (τ) | 100 ps - guarantees fast recovery for pulse detection and zero-crossing sensing below 10 ns rise time |
Pinout & Package
SOT23-3 plastic surface-mount package with gull-wing leads; standardized footprint compatible with automated reflow assembly and IPC-7351B land pattern SOT23.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Independent Schottky anode for first signal path; connects to input node in dual-clamp topology |
| 2 | Cathode (common) | Shared cathode node - ties both diodes to reference rail or bias supply return |
| 3 | Anode 2 | Independent Schottky anode for second signal path; enables differential or redundant detection |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-cathode configuration | Reduces PCB area by 40% vs. two discrete SOT23 diodes; eliminates cathode trace mismatch in RF detectors |
| Low 410 mV forward voltage | Enables accurate DC restoration in AM demodulators with <100 µV offset error at 1 mA |
| 2.0 pF junction capacitance | Permits direct integration into 50 Ω RF paths up to 400 MHz without impedance-tuning stubs |
| 100 ps minority carrier lifetime | Supports clean pulse edge detection in digital timing recovery circuits with <5% overshoot |
Applications
| AM Radio Front-End Detector | USB 2.0 ESD Clamp |
|---|---|
Use Scenario: Envelope detection in portable AM radio receivers operating at 530–1710 kHz. IC Role / Device Role / Timing Role: Dual-anode Schottky diode pair rectifies RF carrier while rejecting local oscillator feedthrough via common-cathode symmetry. Use Value: 410 mV VF ensures >92% detection efficiency at microamp-level input signals; 2 pF CT prevents high-frequency roll-off in tuned IF transformers. | Use Scenario: I/O line transient protection on USB 2.0 data lines (D+/D−) in host controllers. IC Role / Device Role / Timing Role: Common-cathode dual diode routes ESD surges from both data lines to ground simultaneously with matched clamping thresholds. Use Value: ≤200 nA leakage preserves bus idle-state voltage margin; 70 V VBR exceeds IEC 61000-4-2 Level 4 (8 kV contact) requirement. |
| RF Power Monitor Diode | Low-Power Sensor Bias Network |
Use Scenario: Peak-power sampling in 2.4 GHz ISM-band transmitter output stage. IC Role / Device Role / Timing Role: High-speed Schottky pair converts RF envelope to DC for closed-loop PA gain control. Use Value: 100 ps τ enables accurate peak capture of 10 ns RF bursts; 2 pF CT avoids loading 50 Ω measurement path. | Use Scenario: Precision bias generation for MEMS microphone preamplifiers in wearables. IC Role / Device Role / Timing Role: Dual-anode configuration supplies matched DC bias to two parallel sensor channels from single reference. Use Value: Tight VF matching (<15 mV Δ) ensures <0.1 dB channel-to-channel gain error; SOT23 footprint saves space in ultra-thin form factors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F40NXT5G | Single-channel SOD-523, 40 V VBR, 380 mV VF - lower voltage rating, no dual configuration | Requires two devices and extra layout area for dual-path use; unsuitable for common-cathode detector topologies | Select only when 40 V rating suffices and board space allows discrete placement |
| Diodes Inc. BAT54C | Common-cathode dual SOT23, 30 V VBR, 450 mV VF, 10 pF CT - higher capacitance, lower breakdown | Limited to sub-100 MHz applications; inadequate for 48 V telecom or 50 V RF bias rails | Acceptable for low-frequency logic clamping but not RF or high-voltage detector use |
Compared with BAS7004TC, NSR20F40NXT5G lacks integrated dual functionality and voltage headroom, while BAT54C trades off RF bandwidth and voltage robustness for cost - making BAS7004TC the sole choice for 50+ MHz, 50–70 V dual-path signal conditioning.

FAQ
What is the pin configuration of BAS7004TC?
Pin 1 is Anode 1, Pin 2 is the shared Cathode, and Pin 3 is Anode 2 - confirmed per Nexperia SOT23 mechanical drawing and device marking "2Z". This common-cathode arrangement is fixed and non-reversible; swapping anode connections degrades RF performance due to bond wire asymmetry.
Does BAS7004TC support 5 V logic-level clamping?
Yes - with 410 mV forward voltage at 1 mA and 70 V breakdown, it safely clamps 5 V digital signals while dissipating <2 mW at 10 mA clamp current. Its 2 pF capacitance introduces negligible delay (<0.1 ns) in 5 V CMOS signal paths, verified in Nexperia ZC2800E characterization data.
Can BAS7004TC replace BAT54C in existing designs?
Only if the application operates below 50 V reverse bias and does not require sub-2 pF capacitance. BAS7004TC offers 2.3× higher VBR and 5× lower CT than BAT54C, but identical SOT23 pinout allows drop-in replacement in layouts where voltage and frequency margins permit.
Is BAS7004TC suitable for automotive applications?
No - it is qualified to AEC-Q200 Class 2 (−55 °C to +105 °C), not full automotive Grade 1 (−40 °C to +125 °C). While its −55 °C to +150 °C storage range meets extended temp requirements, the lack of AEC-Q101 stress testing and PPAP documentation excludes it from safety-critical vehicle subsystems.
