Product details
Overview
BAS516-QYL from Nexperia is a high-speed switching diode in SOD523 (SC-79) package, rated for 100 V reverse voltage, 4 ns reverse recovery time, and qualified to AEC-Q101 for automotive use. It serves as a fast-switching signal path component in power supply snubbers, ESD protection circuits, and logic-level clamping networks.
For engineers reviewing the BAS516-QYL datasheet, BAS516-QYL pinout, BAS516-QYL application, or BAS516-QYL equivalent, key selection criteria include trr ≤ 4 ns, VR = 100 V, IR ≤ 0.5 µA at 80 V, Cd = 1 pF at 0 V, and thermal resistance Rth(j-sp) = 120 K/W - all critical for high-frequency switching integrity and thermal reliability in space-constrained automotive modules.
Technical Context
The BAS516-QYL employs a planar epitaxial silicon structure optimized for minimal minority-carrier storage, enabling sub-4 ns reverse recovery under IF = IR = 10 mA with RL = 100 Ω. Its low 1 pF capacitance at 0 V reverse bias supports >1 GHz small-signal switching stability.
Designed for AEC-Q101 compliance, it sustains junction temperatures up to 150 °C and operates across −65 °C to +150 °C ambient, with Ptot = 500 mW at Tsp ≤ 90 °C and IFSM = 4 A for 1 µs pulses - making it suitable for transient suppression in 12 V/48 V automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR / VRRM | 100 V - supports full derating margin for 48 V automotive bus transients and ISO 7637-2 pulse 1/2a suppression. |
| trr | 4 ns - enables clean commutation in >50 MHz PWM circuits without shoot-through risk in half-bridge gate drivers. |
| IR @ 80 V | 0.5 µA - ensures negligible leakage current in battery-monitoring voltage dividers over temperature. |
| Cd @ 0 V | 1 pF - maintains signal integrity in RF detector and high-speed data line clamping applications. |
| Rth(j-sp) | 120 K/W - allows direct thermal coupling to PCB copper pour for passive cooling in compact ADAS sensor modules. |
| IF(max) | 250 mA continuous - sufficient for LED indicator driving and low-power logic-level translation in infotainment control ICs. |
Pinout & Package
Package: SOD523 (SC-79), ultra-small surface-mount plastic package measuring 1.2 mm × 0.8 mm × 0.6 mm with flat lead profile optimized for automated placement and reflow soldering on dense automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K (cathode) | Connected to higher-potential node during forward conduction; solder tab provides primary thermal path to PCB. |
| 2 | A (anode) | Connected to lower-potential node; terminal geometry minimizes parasitic inductance in high-dI/dt paths. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns ensures minimal dead-time distortion in synchronous rectifiers and flyback snubbers. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and HAST - no additional qualification required for Tier-1 BOMs. |
| Low leakage current | IR ≤ 0.5 µA at 80 V enables stable biasing in precision analog front-ends without drift. |
| Ultra-small footprint | SOD523 package saves >60% board area vs. SOD323 - critical for camera module and radar SoM miniaturization. |
Applications
| Automotive Body Control Module (BCM) | USB-C ESD Protection Circuit |
|---|---|
Use Scenario: Clamping inductive kickback from door lock actuators and mirror position motors. IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode placed across relay coils and brushed DC motor windings. Use Value: Prevents >100 V transients from damaging MCU GPIOs and CAN transceivers while maintaining <4 ns turn-off to avoid cross-conduction. |
Use Scenario: Low-capacitance signal-line clamping on USB 2.0 D+/D− lines before Type-C connector. IC Role / Device Role / Timing Role: Bidirectional ESD clamp with cathode tied to VBUS and anode to signal line. Use Value: 1 pF capacitance preserves signal rise/fall times; 100 V rating withstands hot-plug surges without degradation. |
| Infotainment Power Sequencing | ADAS Camera Bias Supply |
Use Scenario: Reverse-polarity protection and sequencing isolation between 5 V microcontroller rail and 3.3 V display driver rail. IC Role / Device Role / Timing Role: Low-leakage series blocking diode ensuring controlled power-up order and preventing backfeed. Use Value: 0.5 µA IR at 80 V eliminates standby current accumulation across multi-rail systems over 15-year vehicle lifetime. |
Use Scenario: Bias voltage stabilization for CMOS image sensor analog supply in rear-view camera modules. IC Role / Device Role / Timing Role: Low-noise decoupling diode in LDO input path to suppress ripple-induced pixel noise. Use Value: 4 ns trr prevents switching noise injection into sensitive analog supply; 120 K/W Rth(j-sp) enables direct thermal anchoring to ground plane. |
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 NSR0230P2T5G | trr = 5 ns; VF = 0.5 V @ 100 mA; SOD-523 package; AEC-Q101 qualified | Higher forward voltage increases conduction loss in high-duty-cycle snubbers | Prefer BAS516-QYL where trr < 4.5 ns is mandatory for >30 MHz switching frequencies |
| Vishay VS-2EDH02HM3/85A | trr = 3.5 ns; VR = 200 V; SOD-323 package; not AEC-Q101 qualified | Larger SOD-323 footprint incompatible with ultra-dense layouts; lacks automotive qualification | Select only for non-automotive industrial designs requiring >100 V VR margin and tighter trr tolerance |
Compared with NSR0230P2T5G and VS-2EDH02HM3/85A, the BAS516-QYL uniquely balances AEC-Q101 compliance, 4 ns trr, 1 pF capacitance, and SOD523 size - making it the optimal choice for space- and reliability-critical automotive signal-path switching where both speed and qualification are non-negotiable.

FAQ
Is BAS516-QYL pin-compatible with BAS516?
Yes - BAS516-QYL shares identical SOD523 pinout (anode on pin 2, cathode on pin 1), same marking code "6", and identical mechanical dimensions per Figure 7 of the datasheet. The "-QYL" suffix denotes tape-and-reel packaging with AEC-Q101 certification; electrical and thermal specs are fully aligned with the base BAS516-Q part.
What is the maximum allowable soldering temperature for BAS516-QYL?
The BAS516-QYL is rated for standard lead-free reflow per J-STD-020, with peak temperature of 260 °C for ≤ 30 seconds. Reflow profile must maintain ramp rates ≤ 3 °C/s and ensure Tsp ≤ 90 °C at the cathode solder point to preserve 500 mW power dissipation capability and avoid delamination.
Can BAS516-QYL be used in bidirectional ESD protection?
No - BAS516-QYL is a unidirectional diode. For bidirectional ESD clamping, two devices must be connected in series opposition (anode-to-anode or cathode-to-cathode). Its 100 V VR rating and 1 pF capacitance make it suitable for such configurations in USB 2.0 or CAN FD lines when paired with matching polarity.
Does BAS516-QYL require derating above 25 °C ambient?
Yes - total power dissipation must be linearly derated above Tamb = 25 °C using Rth(j-sp) = 120 K/W. At Tamb = 85 °C, maximum allowed Ptot drops to 260 mW. Derating follows Ptot(Tamb) = 500 mW × (1 − (Tamb − 25)/125), verified by thermal simulation per Figure 2 and Table 6 in the datasheet.
