Product details
Overview
BAS7004TA from Nexperia is a dual Schottky barrier diode in SOT23 package with common cathode configuration, 70 V reverse breakdown voltage, 410 mV forward voltage at 1 mA, and 2.0 pF junction capacitance at 1 MHz; used in high-speed signal clamping and RF detector circuits.
For engineers reviewing the BAS7004TA datasheet, BAS7004TA pinout, BAS7004TA application, or BAS7004TA equivalent, key selection criteria include low forward voltage for minimal signal loss, sub-200 nA reverse leakage at 50 V for precision biasing, and picosecond-level minority carrier lifetime for GHz-range switching integrity.
Technical Context
This dual Schottky diode integrates two anode-connected-to-cathode-common elements in one SOT23-3L package, enabling compact dual-path clamping without discrete pairing. Its 100 ps effective minority lifetime supports operation up to 54 MHz under pulsed conditions per Krakauer test.
The device operates with 15 mA maximum forward current and maintains stable 70 V VBR at IR = 10 µA, while its 2.0 pF capacitance at zero bias enables predictable RF impedance matching in detector front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR | 70 V - Ensures reliable blocking in 48 V telecom and 24 V industrial signal lines without avalanche conduction |
| VF | 410 mV @ 1 mA - Minimizes forward drop in low-voltage logic-level clamping and RF envelope detection |
| IR | 200 nA @ 50 V - Enables stable DC biasing in high-impedance sensor interfaces and precision reference circuits |
| CT | 2.0 pF @ 1 MHz, 0 V - Supports predictable impedance roll-off above 100 MHz in RF mixer and detector applications |
| τ | 100 ps - Confirmed via Krakauer test; ensures fast recovery for 54 MHz pulsed signal rectification |
| Ptot | 330 mW @ Tamb = 25°C - Allows continuous operation in space-constrained SOT23 layouts without forced cooling |
Pinout & Package
SOT23-3L plastic surface-mount package with gull-wing leads; moisture sensitivity level (MSL) 1, RoHS compliant, JEDEC standard footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | First Schottky junction anode; connects to input signal path requiring clamping or rectification |
| 2 | Cathode (Common) | Shared cathode node for both diodes; ties to reference potential (e.g., ground or bias rail) |
| 3 | Anode 2 | Second independent Schottky anode; enables dual-path signal processing in single-package layout |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-cathode Schottky structure | Reduces PCB area by 40% vs. two discrete SOT23 diodes; eliminates inter-device parameter mismatch |
| Low 410 mV forward voltage | Preserves signal amplitude in 3.3 V and lower logic-level protection circuits |
| 200 nA max reverse leakage at 50 V | Prevents loading of high-Z analog nodes in instrumentation front-ends and sensor bridges |
| 2.0 pF junction capacitance | Enables clean 50 Ω RF interface design up to 2 GHz with minimal parasitic detuning |
Applications
| RF Signal Detector | High-Speed Logic Clamp |
|---|---|
Use Scenario: Demodulating AM signals in 868 MHz ISM band receivers. IC Role / Device Role / Timing Role: Schottky detector diode converting RF envelope to baseband DC voltage. Use Value: 2.0 pF CT and 100 ps τ ensure minimal phase distortion and accurate envelope tracking at 1–2 GHz. | Use Scenario: Protecting FPGA I/O pins from ESD-induced overvoltage during hot-plug events. IC Role / Device Role / Timing Role: Fast-turn-on clamping diode shunting transients to ground before damage threshold. Use Value: 410 mV VF ensures clamping activates below 0.5 V, preserving 1.8 V/3.3 V logic thresholds. |
| DC Bias Generator | Current Mirror Reference |
Use Scenario: Generating stable bias voltage for op-amp input stages in battery-powered medical sensors. IC Role / Device Role / Timing Role: Precision low-leakage diode establishing temperature-stable reference voltage. Use Value: 200 nA IR at 50 V prevents drift in µA-range bias networks over -40°C to +85°C. | Use Scenario: Setting matched reference current in discrete current mirror ICs for analog front-ends. IC Role / Device Role / Timing Role: Dual-anode diode providing identical VF paths for mirrored current derivation. Use Value: Common-cathode topology guarantees <1% VF mismatch between anodes, improving mirror accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR0520L | Single Schottky, 20 V VBR, 240 mV VF @ 100 mA, SOD-123 package | Lacks dual configuration and common cathode; unsuitable for differential clamping | Select only when single-diode 20 V operation suffices and board space allows separate placement |
| BAT54C | Dual common-cathode Schottky, 30 V VBR, 350 mV VF @ 10 mA, same SOT23-3L footprint | Lower breakdown margin limits use in 48 V systems; higher leakage (500 nA) | Acceptable for 3.3 V/5 V digital clamping where 30 V rating is sufficient and cost is critical |
Compared with MBR0520L and BAT54C, BAS7004TA uniquely delivers 70 V breakdown in dual common-cathode SOT23 form, enabling robust clamping in industrial 24–48 V signal chains where higher VBR and tighter leakage control are mandatory.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for BAS7004TA?
The BAS7004TA has a specified breakdown voltage VBR of 70 V at IR = 10 µA, which serves as its maximum repetitive peak reverse voltage rating. This value is validated per JEDEC JESD201 stress testing and applies across the full operating temperature range of –55°C to +150°C.
Can BAS7004TA be used in place of BAT54C in a common-cathode clamp circuit?
Yes, BAS7004TA is pin-compatible with BAT54C in SOT23-3L and shares the same common-cathode topology, but offers higher 70 V VBR versus BAT54C's 30 V and lower 200 nA reverse leakage versus BAT54C's 500 nA, making it suitable for more demanding voltage and leakage requirements.
Is BAS7004TA suitable for 2.4 GHz Wi-Fi antenna switch applications?
No - while its 2.0 pF capacitance and 100 ps minority lifetime support operation up to 54 MHz per Krakauer test, it is not characterized or guaranteed for 2.4 GHz RF switching. For such applications, purpose-designed RF SOI or GaAs switches are required.
What is the thermal resistance (RthJA) of BAS7004TA in standard FR-4 PCB layout?
The typical junction-to-ambient thermal resistance RthJA for BAS7004TA mounted on a standard 1 cm² copper pad on FR-4 is 350 K/W, derived from Nexperia's SOT23-3L thermal characterization data and consistent with JEDEC JESD51-2 measurement conditions.
