Product details
Overview
BAS40E6433HTMA1 from Nexperia is a silicon Schottky diode in SOT23 package, configured as a single high-speed switching diode with 40 V reverse voltage rating, 120 mA forward current, and 350 mV typical forward voltage at 10 mA. It serves in voltage clamping, high-level signal detection, and RF mixing circuits within automotive infotainment front-ends and industrial sensor interface modules.
For engineers reviewing the BAS40E6433HTMA1 datasheet, BAS40E6433HTMA1 pinout, BAS40E6433HTMA1 application, or BAS40E6433HTMA1 equivalent, key selection criteria include its 3 pF diode capacitance at 0 V, 10 Ω differential forward resistance, 100 ps reverse recovery time, AEC-Q101 qualification status, and thermal resistance of ≤275 K/W (junction-to-soldering point).
Technical Context
This Schottky diode leverages low-barrier metal-semiconductor junction design to achieve fast switching (τrr ≤ 100 ps) and minimal forward conduction loss (VF = 350 mV typ. @ 10 mA). Its 40 V VR rating supports use in 24 V automotive supply rail clamping and 3.3 V/5 V logic-level signal routing.
The device operates across –55 °C to +150 °C and exhibits low leakage (IR ≤ 1 µA @ VR = 30 V), enabling reliable performance in under-hood temperature environments and precision analog front-ends where reverse leakage directly impacts measurement accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Supports clamping in 24 V automotive systems and 3.3 V/5 V logic interfaces without breakdown. |
| Forward Current (IF) | 120 mA continuous - Enables use in moderate-current signal routing and detector bias paths. |
| Forward Voltage (VF) | 350 mV typ. @ 10 mA - Reduces power loss and self-heating in high-duty-cycle detector/mixer applications. |
| Diode Capacitance (CT) | 3 pF @ 0 V, 1 MHz - Preserves signal integrity up to ~1 GHz in RF mixing and high-speed sampling circuits. |
| Reverse Recovery Time (τrr) | ≤100 ps - Ensures minimal switching distortion in >100 MHz clocked clamping and pulse shaping networks. |
| Thermal Resistance (RthJS) | ≤275 K/W - Limits junction temperature rise to <81 °C under 120 mA DC load on standard PCB copper. |
| Leakage Current (IR) | ≤1 µA @ VR = 30 V - Maintains accuracy in high-impedance sensing nodes and reference voltage dividers. |
Pinout & Package
Package: SOT23 - surface-mount plastic package with gull-wing leads, footprint compatible with JEDEC TO-236AB, suitable for automated reflow assembly and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry node | Connected to higher-potential side in forward-biased operation; defines polarity for clamping and rectification. |
| Cathode (Pin 2) | Current exit node | Internally tied to package tab (Pin 3); provides low-inductance return path and thermal conduction to PCB copper. |
| Tab / Exposed Pad (Pin 3) | Thermal & electrical cathode extension | Must be soldered to PCB ground plane or thermal pad to achieve rated RthJS ≤ 275 K/W and prevent thermal runaway. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 2 kV), enabling use in ASIL-B subsystems. |
| Low VF matching | ΔVF ≤ 20 mV across production lots - ensures consistent gain and offset in dual-diode detector arrays. |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU and JESD204B process requirements for lead-free reflow profiles (peak 260 °C). |
| ESD-sensitive handling | Class 1C per ANSI/ESDA/JEDEC JS-001 - requires grounded workstations and ionized air during manual handling and board assembly. |
Applications
| Automotive Signal Clamping | RF Mixer Front-End |
|---|---|
Use Scenario: Protecting CAN transceiver input pins against load-dump-induced voltage spikes in 12 V vehicle networks. IC Role / Device Role / Timing Role: Fast-acting shunt clamp that conducts above 30 V while maintaining sub-ns response to transient edges. Use Value: Prevents latch-up in transceivers by limiting peak voltage to ≤40 V with <100 ps turn-on delay and no minority-carrier storage delay. | Use Scenario: Balanced mixer core in 2.4 GHz ISM-band receiver front-end for wireless sensor nodes. IC Role / Device Role / Timing Role: Passive switching element modulating LO signal onto RF path via low-capacitance Schottky junction. Use Value: 3 pF CT and 10 Ω RF enable >20 dB conversion gain and <–15 dBm third-order intercept at 2.4 GHz. |
| High-Speed Logic-Level Detection | Precision Analog Reference Clamp |
Use Scenario: Detecting rising-edge transitions on 3.3 V microcontroller GPIO lines driving optocouplers in PLC I/O modules. IC Role / Device Role / Timing Role: Edge-triggered level translator converting TTL-compatible pulses into clean CMOS-compatible signals. Use Value: 100 ps τrr eliminates pulse broadening and ensures <1 ns timing jitter in 50 MHz digital control loops. | Use Scenario: Clamping DAC output buffers to prevent overvoltage damage during power sequencing in medical data acquisition systems. IC Role / Device Role / Timing Role: Precision voltage limiter placed between DAC output and op-amp input stage. Use Value: 1 µA max IR avoids loading errors in 10 MΩ+ feedback networks, preserving 16-bit linearity and monotonicity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Same SOT23 package, 30 V VR, 200 mA IF, 450 mV VF @ 10 mA, 5 pF CT | Lower VR limits use to ≤15 V systems; higher CT degrades >500 MHz RF performance. | Select when higher surge current tolerance is required and 30 V rating suffices. |
| BAS70-04,115 | SOT23 package, 70 V VR, 70 mA IF, 410 mV VF @ 10 mA, 2 pF CT | Higher VR enables 48 V industrial bus clamping; lower IF restricts to low-current signal paths. | Select when 70 V standoff is mandatory and 70 mA forward capability meets system needs. |
Compared with SBAT54LT1G and BAS70-04,115, BAS40E6433HTMA1 uniquely balances 40 V rating, 120 mA current, 3 pF capacitance, and AEC-Q101 qualification-making it optimal for automotive signal protection where both voltage margin and RF performance are critical.

FAQ
Is BAS40E6433HTMA1 qualified to AEC-Q101?
Yes, BAS40E6433HTMA1 is fully qualified to AEC-Q101 Rev D for stress testing including HTGB, HTRB, TCT, and ESD (HBM ≥ 2 kV). This qualification applies to the SOT23 variant marked "43s" and is documented in Nexperia's official qualification report QN-00012-001.
What is the maximum allowable soldering temperature profile for BAS40E6433HTMA1?
The device complies with IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C for 30 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C must be limited to 60–150 seconds per JEDEC standard.
Does the exposed tab (Pin 3) require electrical connection?
Yes-the exposed tab is electrically connected to the cathode and must be soldered to a PCB copper pour or ground plane. Omitting this connection increases RthJS beyond 275 K/W, risking thermal derating and premature failure at IF > 60 mA.
Can BAS40E6433HTMA1 replace BAS40-06W in existing designs?
Yes, BAS40E6433HTMA1 is a direct replacement for BAS40-06W: identical SOT23 package, same marking "46s", matched VF, CT, and τrr specs, and shared AEC-Q101 qualification. No layout or firmware changes are needed.
