Product details
Overview
BAS16Q-7-F from Diodes Incorporated is an AEC-Q101 qualified surface-mount fast switching diode in SOT23 package, with 75 V peak repetitive reverse voltage, 300 mA forward current rating, and 4.0 ns reverse recovery time. It serves as a high-speed signal path switch or clamp in automotive power management, ECU input protection, and CAN bus interface circuits.
For engineers reviewing the BAS16Q-7-F datasheet, BAS16Q-7-F pinout, BAS16Q-7-F application, or BAS16Q-7-F equivalent, key selection criteria include reverse recovery speed, AEC-Q101 qualification status, SOT23 thermal performance under pulsed load, and leakage behavior at elevated junction temperature (≤150°C).
Technical Context
This diode employs a planar epitaxial silicon structure optimized for low charge storage and rapid carrier recombination, enabling sub-4 ns tRR at IF = IR = 10 mA with 0.1×IR tail current. Its 75 V VRRM supports 24 V automotive system transient suppression up to ISO 7637-2 Pulse 1/2a.
The device operates across –55 °C to +150 °C with <1.0 µA IR at 75 V and 25 °C, rising to 50 µA at 75 V and +150 °C - a critical parameter for low-power wake-up circuit integrity in always-on vehicle modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 75 V - Withstands repetitive transients in 24 V automotive systems without breakdown. |
| tRR | 4.0 ns - Enables clean switching in >10 MHz digital signal routing and PWM edge detection. |
| IF | 300 mA continuous - Supports logic-level clamping and moderate-current signal steering. |
| RθJA | 357 °C/W - Requires minimal copper area (1 in², 2 oz) for thermal compliance at full DC load. |
| TJ Range | –55 to +150 °C - Validated for engine bay and transmission control unit mounting locations. |
| VF @ 10 mA | 0.715–0.855 V - Ensures low forward drop in bias networks and level-shifting paths. |
| CT | 2.0 pF @ 0 V - Minimizes capacitive loading on high-impedance analog or RF signal nodes. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with matte tin-plated Alloy 42 leadframe; moisture sensitivity level 1 per J-STD-020; weight 0.008 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node in clamping or steering configuration. |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Typically tied to ground or reference rail; defines polarity-sensitive protection direction. |
| NC / Heat Sink (Pin 3) | No internal connection | Unused terminal; may be left floating or grounded for mechanical stability only. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBD4148-7-F | Same electrical specs but not AEC-Q101 qualified; no PPAP support or IATF 16949 manufacturing traceability. | Restricted to industrial/commercial use; unsuitable for automotive production BOMs. | Select when cost sensitivity outweighs automotive qualification requirements. |
| BAS16-7-F | Identical die and SOT23 package, but lacks AEC-Q101 validation and automotive change control documentation. | Approved for general-purpose switching where automotive reliability standards are not mandated. | Choose for legacy designs or non-automotive applications requiring same performance at lower documentation overhead. |
Compared with MMBD4148-7-F and BAS16-7-F, the BAS16Q-7-F adds verified automotive process controls, PPAP readiness, and documented AEC-Q101 test reports - making it the sole option for Tier 1-supplied ECUs requiring full compliance traceability.

FAQ
Is BAS16Q-7-F pin-compatible with MMBD4148-7-F?
Yes - both use identical SOT23-3 package with standard pin 1 (anode), pin 2 (cathode), and pin 3 (NC). Mechanical dimensions, pad layout, and soldering profiles match exactly per Diodes' package outline DS12003 Rev. 33-2.
What is the maximum allowable junction temperature during pulsed operation?
The absolute maximum junction temperature is +150 °C under all conditions. Derating begins at +25 °C ambient, with linear reduction to zero power at +150 °C ambient per Figure 1 in DS12003 - confirming safe operation at full IF = 300 mA up to +125 °C ambient with appropriate PCB copper area.
Does BAS16Q-7-F meet ISO 7637-2 Pulse 5a requirements?
No - it is not rated for load-dump suppression. Its 75 V VRRM supports ISO 7637-2 Pulse 1 (−100 V) and Pulse 2a (+100 V), but load dump (Pulse 5a: +75 V sustained) requires higher-voltage TVS devices like SMAJ7.0A or similar.
Can BAS16Q-7-F replace BAT54 in low-voltage applications?
No - BAT54 is a Schottky diode with ~0.3 V VF, while BAS16Q-7-F is a PN junction diode with 0.715–1.25 V VF. Substituting it in 3.3 V logic clamping would increase forward drop and reduce noise margin; use only where its faster tRR and higher VRRM justify the higher VF.
