Product details
Overview
BAS16H-Q from Nexperia is a high-speed switching diode in SOD123F surface-mount package, rated for 100 V repetitive peak reverse voltage (VRRM), 4 ns reverse recovery time (trr), and 215 mA continuous forward current (IF), used in automotive-grade signal routing and clamping circuits.
For engineers reviewing the BAS16H-Q datasheet, BAS16H-Q pinout, BAS16H-Q application, or BAS16H-Q equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, and automotive-grade reliability context essential for high-reliability board-level design and BOM validation.
Technical Context
The BAS16H-Q is a silicon planar epitaxial switching diode optimized for fast transient response, with trr ≤ 4 ns under IF = IR = 10 mA conditions and Cd = 1.5 pF at VR = 0 V, f = 1 MHz - enabling clean edge handling in digital logic interfaces and ESD-protected signal lines.
Its AEC-Q101 qualification confirms operation across −65 °C to +150 °C ambient, supported by Rth(j-a) = 330 K/W (FR4 strip line) and Rth(j-sp) = 70 K/W (cathode solder point), making it suitable for under-hood automotive modules where thermal margin and switching fidelity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports 24 V and 48 V automotive power rail clamping without breakdown |
| trr | 4 ns - enables reliable operation in >100 MHz digital signal paths and pulse-width modulated control loops |
| IF | 215 mA - sufficient for logic-level signal steering and low-power sensor interface protection |
| IR @ VR=80 V | 0.5 µA - ensures minimal leakage in battery-backed or always-on monitoring circuits |
| Cd @ VR=0 V | 1.5 pF - minimizes capacitive loading on high-impedance analog or RF-adjacent nodes |
| VF @ IF=10 mA | 855 mV - low forward drop preserves signal swing in level-shifting and OR-ing applications |
| Rth(j-sp) | 70 K/W - direct cathode-to-PCB thermal path improves reliability in thermally constrained layouts |
Pinout & Package
Encapsulated in the SOD123F plastic surface-mount package (2.6 mm × 1.6 mm × 1.1 mm body), the BAS16H-Q uses a two-terminal configuration with defined anode and cathode polarity for unidirectional conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K (cathode) | Connected to lower-potential node; primary heat-sinking terminal via solder pad |
| 2 | A (anode) | Connected to higher-potential node; carries forward current during conduction phase |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns enables use in 100+ MHz clock distribution and data line clamping |
| AEC-Q101 qualified | Validated for automotive under-hood environments including temperature cycling and humidity testing |
| Low leakage current | IR ≤ 0.5 µA at 80 V ensures stable biasing in always-on sensor front-ends |
| Small SMD footprint | SOD123F package allows dense placement in space-constrained ECUs and ADAS modules |
| Low junction-to-solder-point thermal resistance | Rth(j-sp) = 70 K/W supports sustained operation near thermal limits without derating |
Applications
| Automotive CAN Transceiver Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines against ESD and load-dump transients in vehicle network gateways. IC Role / Device Role / Timing Role: Fast-switching clamp diode placed between bus line and ground, conducting only during overvoltage events. Use Value: 4 ns trr ensures minimal disruption to 1 Mbps CAN signaling; 100 V VRRM withstands ISO 7637-2 Pulse 5a. |
Use Scenario: Bidirectional ESD protection on D+/D− lines of USB 2.0 host ports in infotainment head units. IC Role / Device Role / Timing Role: Low-capacitance (1.5 pF) shunt diode providing sub-nanosecond response to ±8 kV HBM transients. Use Value: Capacitance below 2 pF avoids signal integrity degradation at 480 Mbps; AEC-Q101 ensures field longevity. |
| Microcontroller GPIO Level Shifting | Power Supply OR-ing Diode |
Use Scenario: Isolating mixed-voltage I/O (e.g., 3.3 V MCU to 5 V peripheral) while preserving rise/fall times. IC Role / Device Role / Timing Role: Unidirectional signal path diode enabling voltage translation without active logic. Use Value: VF = 855 mV at 10 mA maintains adequate noise margin; 215 mA IF rating exceeds GPIO sink capability. |
Use Scenario: Preventing backfeed between redundant 12 V supplies in telematics control units. IC Role / Device Role / Timing Role: Low-forward-drop, fast-recovery diode in series with each supply rail. Use Value: 855 mV VF reduces power loss vs. Schottky alternatives; 100 V rating covers surge margins in 12 V systems. |
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 |
|---|---|---|---|
| ON Semiconductor MMBD1203LT1G | VRRM = 100 V, trr = 4 ns, but Cd = 2.0 pF and IR = 1.0 µA @ 80 V | Higher capacitance limits use in >50 MHz signal paths; acceptable for general-purpose clamping | Select when cost sensitivity outweighs marginal signal integrity requirements |
| Diodes Incorporated BAV99W-7-F | Dual-series configuration in SOT-363; per-diode VRRM = 70 V, trr = 4 ns, Cd = 2.5 pF | Limited to 70 V systems; dual layout saves board area but increases parasitic coupling risk | Prefer for space-constrained dual-channel designs where 70 V rating suffices |
Compared with MMBD1203LT1G and BAV99W-7-F, the BAS16H-Q offers the lowest leakage (0.5 µA) and lowest capacitance (1.5 pF) among AEC-Q101-qualified SOD123F diodes, making it optimal for high-fidelity automotive signal conditioning where both speed and precision matter.

FAQ
Is BAS16H-Q suitable for 12 V automotive power rail clamping?
Yes - with VRRM = 100 V and surge capability up to 4 A (tp = 1 µs), the BAS16H-Q safely clamps ISO 7637-2 Pulse 1 (−150 V/2 Ω) and Pulse 3b (±100 V) transients on 12 V rails. Its 150 °C max junction temperature and AEC-Q101 qualification confirm suitability for under-hood deployment.
What is the maximum PCB copper area needed to achieve Rth(j-a) = 330 K/W?
The 330 K/W Rth(j-a) value assumes mounting on an FR4 PCB with a 60 µm copper strip line - no additional thermal pad required. For improved thermal performance, a 1 cm² cathode-side copper pour reduces Rth(j-a) to 150 K/W per datasheet Table 6, footnote [2].
Does BAS16H-Q have a marked polarity indicator on the package?
Yes - the SOD123F package features a single bar marking aligned with Pin 1 (cathode), matching the "A1" top-side marking specified in Table 4. This bar corresponds to the cathode end in the simplified outline (Figure 7) and ensures correct orientation during automated placement.
Can BAS16H-Q replace BAS16 in existing designs?
Yes, with caveats: BAS16H-Q shares identical pinout and basic ratings (VRRM, trr), but adds AEC-Q101 qualification, tighter IR spec (0.5 µA vs. typical 1 µA), and improved thermal resistance. No layout change is needed, though revalidation of leakage-sensitive circuits is recommended.
