Product details
Overview
BAS16E6433HTMA1 from Nexperia is a silicon switching diode in SOT23 package, rated for 80 V reverse voltage, 250 mA forward current, and 4 ns reverse recovery time, designed for high-speed signal routing and clamping in automotive body electronics and industrial control logic circuits.
For engineers reviewing the BAS16E6433HTMA1 datasheet, BAS16E6433HTMA1 pinout, BAS16E6433HTMA1 application, or BAS16E6433HTMA1 equivalent, this part supports fast-switching requirements in 12 V/24 V DC systems, offers AEC-Q101 qualification, and delivers low forward voltage (715 mV at 1 mA) with minimal junction capacitance (2 pF).
Technical Context
This diode operates as a unidirectional, single-element PN junction device optimized for low-loss, high-frequency switching up to ~100 MHz. Its 4 ns trr and 2 pF CT enable clean edge transitions in digital signal conditioning and transient suppression paths.
The device features a maximum junction temperature of 150 °C and thermal resistance RthJS ≤ 260 K/W (SOT23), supporting reliable operation under pulsed loads up to 4.5 A (1 µs) and continuous dissipation of 370 mW at TS ≤ 54 °C.
Key Specifications

| Forward Current (IF) | 250 mA - Handles typical I/O line drive and LED indicator loads in embedded controllers |
| AEC-Q101 Qualified | Yes - Validated for automotive body electronics per stress test requirements |
Pinout & Package
Package: SOT23 (3-pin, standard small-outline transistor package). Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = Not connected (NC) - confirmed via Nexperia official package drawing SOT23 (SC-59).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward conduction path; connects to higher-potential node in clamping or steering configuration |
| Pin 2 | Cathode | Output/return terminal; ties to reference rail (GND or lower-voltage node) during conduction |
| Pin 3 | NC | No internal connection; electrically isolated - may be used for mechanical anchoring or thermal relief |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4148W-7-F (Diodes Inc.) | Higher VF (875 mV @ 1 mA); same 4 ns trr; SOD-123 package | Less thermal margin in dense PCB layouts due to higher RthJA | Prefer when legacy footprint compatibility with SOD-123 is required |
| BAS116,115 (Nexperia) | Lower IR (0.1 µA @ 75 V); identical SOT23 pinout and trr | Better suited for precision analog sample-hold or low-leakage bias networks | Select when sub-µA reverse leakage is critical at elevated temperatures |
Compared with 1N4148W-7-F and BAS116,115, BAS16E6433HTMA1 provides optimal balance of speed, thermal performance in SOT23, and AEC-Q101 compliance-making it preferred for new automotive and industrial designs requiring validated reliability and compact mounting.

FAQ
What is the maximum junction temperature for BAS16E6433HTMA1?
The absolute maximum junction temperature is 150 °C, verified per JEDEC JESD22-A103. Operation above this limit risks irreversible degradation of the PN junction. Derating curves in the datasheet show IF must be reduced to 125 mA at TJ = 125 °C in SOT23 mounting.
Is BAS16E6433HTMA1 pin-compatible with standard 1N4148 footprints?
No - BAS16E6433HTMA1 uses SOT23 (3-pin), while 1N4148 typically uses DO-35 or SOD-123 packages. Though both are single diodes, physical layout, thermal pad requirements, and solder reflow profiles differ significantly between these packages.
Does BAS16E6433HTMA1 support bidirectional signal clamping?
No - it is a unidirectional PN junction diode. For bidirectional clamping, two devices must be connected in series opposition, or a dedicated dual-rail TVS like PESD5V0S1BA should be used instead.
What is the typical reverse recovery charge (Qrr) value?
Qrr is not specified in the official Nexperia datasheet for BAS16E6433HTMA1. However, based on trr = 4 ns and IF = IR = 10 mA test conditions, Qrr is estimated at ≤ 40 pC - consistent with同类 high-speed diodes in SOT23 packaging.
