Product details
Overview
BAS16W-7-F from Diodes Incorporated is a surface-mount fast-switching silicon switching diode in SOT323 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It delivers high conductance with VF = 0.715 V at IF = 1.0 mA and CT = 2.0 pF at VR = 0 V, f = 1 MHz, enabling use in high-speed signal routing and clamping circuits.
For engineers reviewing the BAS16W-7-F datasheet, BAS16W-7-F pinout, BAS16W-7-F application, or BAS16W-7-F equivalent, key selection criteria include reverse recovery speed, low forward voltage at low currents, junction-to-ambient thermal resistance (625 °C/W), and compatibility with automated SMT assembly on FR4 boards using standard SOT323 pad layouts.
Technical Context
This diode operates as a unidirectional, low-capacitance, fast-recovery switching element optimized for general-purpose digital logic interfacing and transient suppression. Its 4.0 ns trr and 2.0 pF CT support operation in 10–100 MHz signal paths, while its 75 V VRRM and 300 mA IF rating suit 3.3 V to 24 V rail-level clamping and level translation.
The device uses an epitaxial planar construction with alloy 42 leadframe and matte tin plating, achieving JEDEC-compliant reliability and moisture sensitivity level 1. Thermal derating begins above 25 °C ambient, with full power dissipation (200 mW) only at TA ≤ 25 °C per Fig. 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 75 V - supports DC blocking up to 75 V in signal path isolation or clamp applications |
| IF | 300 mA - enables direct drive of small-signal loads like LED indicators or logic inputs without external buffering |
| trr | 4.0 ns - ensures minimal switching distortion in >25 MHz digital edge detection or pulse shaping circuits |
| VF @ 1 mA | 0.715 V - provides low-voltage drop for precision biasing and low-power logic interface protection |
| CT @ 0 V | 2.0 pF - minimizes capacitive loading on high-impedance nodes such as oscillator feedback paths or RF detector inputs |
| RθJA | 625 °C/W - requires thermal-aware PCB layout (e.g., copper pour under exposed pad not applicable-SOT323 has no thermal pad) |
Pinout & Package
Package: SOT323 - ultra-small plastic surface-mount package (2.15 mm × 2.10 mm × 0.95 mm), lead-free, halogen-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node during conduction; polarity must match schematic symbol orientation |
| Cathode (Pin 2) | Forward current exit / reverse voltage reference | Marked by cathode band on package top view; ties to ground or lower-potential rail in clamp configurations |
| NC / Heat Sink (Pin 3) | No internal connection | Electrically isolated terminal; may be left floating or tied to ground for mechanical stability-no thermal benefit |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching speed | 4.0 ns reverse recovery time enables reliable operation in 10–50 MHz clock distribution and data line steering |
| Ultra-small SOT323 footprint | 2.15 mm × 2.10 mm area saves board space in dense portable electronics and multi-channel sensor interfaces |
| High conductance at low current | VF = 0.715 V @ 1 mA improves accuracy in precision bias networks and analog switch leakage control |
| Lead-free & green compliance | Meets RoHS 3 (2015/863/EU), <900 ppm Br/Cl, <1000 ppm Sb-supports automotive and medical end-equipment compliance |
Applications
| Logic Level Translation | ESD Protection Clamp |
|---|---|
Use Scenario: Bidirectional voltage translation between 3.3 V microcontroller GPIO and 5 V peripheral I/O lines. IC Role / Device Role / Timing Role: Passive clamping diode placed between rails to limit voltage excursion beyond safe logic thresholds. Use Value: 4.0 ns trr prevents signal integrity degradation during fast edge transitions; 2.0 pF CT avoids RC delay skew on high-speed data lines. | Use Scenario: Low-capacitance I/O protection for USB 2.0 D+/D− pins against ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Fast-turn-on shunt path that diverts ESD current before IC input structures are overstressed. Use Value: 0.715 V VF at low current ensures rapid conduction onset; 75 V VRRM withstands normal operating voltage margins without leakage. |
| High-Speed Signal Routing | Power Supply Sequencing Diode |
Use Scenario: Selective signal gating in FPGA configuration JTAG chains or multiplexed test access ports. IC Role / Device Role / Timing Role: Unidirectional pass element controlled by enable bias, exploiting fast turn-on/turn-off behavior. Use Value: Sub-5 ns trr eliminates pulse narrowing or timing jitter in 25+ MHz serial control signals. | Use Scenario: OR-ing diode in dual-rail power management for industrial PLC modules requiring 3.3 V and 5 V domain sequencing. IC Role / Device Role / Timing Role: Isolation diode preventing backfeed between independent SMPS outputs during startup/shutdown transients. Use Value: 300 mA IF rating handles typical auxiliary rail currents; 200 mW PD allows continuous operation with minimal heatsinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBD4148W-7-F | Identical electrical specs (VRRM = 75 V, trr = 4.0 ns, VF = 0.715 V @ 1 mA); same SOT323 package and marking convention | No functional difference; dual-marked part per Diodes Inc. documentation DS30094 | Select when cross-reference compatibility with legacy MMBD4148W BOMs is required |
| 1N4148W-7-F | Slightly higher VF (0.72 V min @ 10 mA), identical trr and VRRM; same SOT323 package but different internal process optimization | Marginally higher forward loss in low-current bias networks; otherwise interchangeable in clamping and routing | Prefer for cost-sensitive consumer designs where 10 mA forward drop is more relevant than 1 mA performance |
Compared with MMBD4148W-7-F, BAS16W-7-F offers identical parametric performance and form factor, while 1N4148W-7-F trades minor VF increase for broader production scalability-making BAS16W-7-F optimal for precision low-current biasing and high-frequency signal integrity.

FAQ
Is BAS16W-7-F pin-compatible with MMBD4148W-7-F?
Yes-BAS16W-7-F and MMBD4148W-7-F share identical SOT323 pinout (anode-cathode-NC), mechanical dimensions, and electrical specifications per Diodes Inc. datasheet DS30094 Rev. 13. Both are marked with KA2 code and follow the same date-code format (YM), confirming functional and physical interchangeability.
What is the maximum operating temperature for continuous use?
The BAS16W-7-F has an operating junction temperature range of –55 °C to +150 °C. At ambient temperatures above 25 °C, power dissipation must be linearly derated per Fig. 1: PD drops to 100 mW at TA = 75 °C and reaches zero at TA = 150 °C, assuming standard FR4 mounting per note 5.
Does BAS16W-7-F meet AEC-Q200 requirements for automotive use?
No-BAS16W-7-F is not AEC-Q200 qualified. Diodes Inc. explicitly states that automotive-grade equivalents carry a Q-suffix (e.g., BAS16WQ-7-F) and are manufactured in IATF 16949-certified facilities. This part is intended for commercial and industrial applications only.
Can BAS16W-7-F replace 1N4148 in through-hole designs?
Only with PCB redesign-BAS16W-7-F is SOT323 surface-mount and incompatible with through-hole footprints. While electrically similar (VRRM, trr, VF), its 2.15 mm × 2.10 mm body and 0.65 mm pin pitch require SMT assembly. For drop-in replacement, use DO-35 packaged 1N4148 or SOD-123 variants like 1N4148WS.
