Product details
Overview
BAS4004E6433HTMA1 from Vishay is a silicon Schottky diode in SOT23 package configured as a common-anode dual diode, rated for 40 V reverse voltage, 120 mA forward current, and 250 mW power dissipation at TS ≤ 56 °C, used for high-speed switching and voltage clamping in automotive signal conditioning circuits.
For engineers reviewing the BAS4004E6433HTMA1 datasheet, BAS4004E6433HTMA1 pinout, BAS4004E6433HTMA1 application, or BAS4004E6433HTMA1 equivalent, key selection criteria include VF matching (≤20 mV), low CT (3 pF typ. @ 0 V), fast trr (≤100 ps), and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This dual common-anode Schottky diode enables independent anode referencing with shared cathode connection, supporting bidirectional clamping or dual-path signal routing. Its low forward voltage (310–720 mV across 1–40 mA) and minimal junction capacitance (3 pF typ.) support high-frequency operation up to several hundred MHz.
The device exhibits fast recovery (trr ≤ 100 ps) and low differential forward resistance (RF = 10 Ω typ. @ 10 kHz), making it suitable for RF detector/mixer stages and transient suppression where minimal signal distortion and insertion loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Supports clamping of 3.3 V/5 V/12 V logic and supply rails without breakdown. |
| Forward Current (IF) | 120 mA - Sustains continuous DC current in signal path protection and level-shifting applications. |
| Forward Voltage (VF) | 310 mV @ 10 mA - Enables low-loss signal rectification and detection in battery-powered RF modules. |
| Junction Capacitance (CT) | 3 pF @ 0 V, 1 MHz - Minimizes capacitive loading on high-impedance RF nodes (e.g., antenna switch control lines). |
| Reverse Recovery Time (trr) | ≤100 ps - Ensures clean switching in >100 MHz clock/data paths and mixer LO injection circuits. |
| Thermal Resistance (RthJS) | 375 K/W - Limits junction temperature rise to safe levels under 120 mA DC load in SOT23 footprint. |
| ESD Rating | HBM Class 2 (≥2 kV) - Meets IEC 61000-4-2 Level 2 for board-level ESD robustness in automotive ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-anode Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR20F40NXT5G | Single diode, 40 V VR, 200 mA IF, SOD-123FL package - lacks dual configuration and VF matching spec. | Requires two devices for dual-path use; higher mounting area and thermal resistance (RthJS = 420 K/W). | Use only when dual-diode integration is unnecessary and board space allows discrete placement. |
| RB520S-40T1G | Common-cathode dual Schottky, 40 V VR, 200 mA IF, SOT-23 - opposite polarity configuration. | Suitable for cathode-referenced clamping; incompatible for anode-referenced topologies without circuit redesign. | Select only if system grounding scheme aligns with common-cathode architecture and VF matching is not required. |
Compared with NSR20F40NXT5G and RB520S-40T1G, BAS4004E6433HTMA1 uniquely delivers AEC-Q101-qualified dual common-anode topology with guaranteed VF matching and optimized RthJS for SOT23 thermal constraints-critical for compact automotive signal conditioning.

FAQ
Is BAS4004E6433HTMA1 qualified to AEC-Q101?
Yes. BAS4004E6433HTMA1 is explicitly qualified per AEC-Q101 Rev D for stress testing including HTGB, HTRB, TCT, and ESD-HBM ≥2 kV. Qualification applies to the SOT23 packaged variant with marking "44s" and lot codes meeting Vishay's automotive traceability requirements.
What is the maximum junction temperature and how is it enforced?
The absolute maximum junction temperature is 150 °C. This limit is enforced via derating curves in the datasheet: at ambient 85 °C, maximum continuous IF drops to ~60 mA for BAS40-04/BAS40-06 variants due to RthJS = 375 K/W and TS ≤ 56 °C thermal constraint.
Can BAS4004E6433HTMA1 be used in RF matching networks?
No. While its 3 pF capacitance and low RF resistance support RF detection and clamping, BAS4004E6433HTMA1 is not characterized for impedance matching or power handling in RF transmission paths. It lacks S-parameter data, power rating above 250 mW, and VSWR specifications required for matching network use.
How does the common-anode configuration affect PCB layout?
The common-anode configuration requires separate anode traces routed to distinct signal sources, with the shared cathode connected directly to a low-inductance ground or bias rail. Layout must minimize loop area between cathode pad and ground plane to preserve trr performance and avoid ringing during fast transients.
