Product details
Overview
BAS416-QZ from Nexperia is a low-leakage, medium-speed switching diode in SOD323 package, featuring 3 pA typical reverse leakage at 75 V, 0.8 µs typical reverse recovery time, and 85 V repetitive peak reverse voltage. It is AEC-Q101 qualified for automotive signal routing and precision biasing where minimal leakage and fast turn-off are critical.
For engineers reviewing the BAS416-QZ datasheet, BAS416-QZ pinout, BAS416-QZ application, or BAS416-QZ equivalent, key selection criteria include reverse leakage performance at elevated temperature, SOD323 thermal resistance (450 K/W), junction temperature limit (150 °C), and compatibility with reflow/wave soldering footprints per Fig. 8–9.
Technical Context
This epitaxial silicon switching diode operates as a unidirectional current path with cathode-anode polarity defined by its SOD323 pinning. Its low IR (0.003 nA typ. @ 75 V, 25 °C) enables high-impedance node protection in sensor front-ends and sample-hold circuits.
The 0.8 µs trr and 1.1 V VF @ 50 mA support medium-speed digital logic clamping and flyback suppression in 12 V/24 V automotive control modules, while its 500 mA IFRM rating allows pulsed current handling in power management sequencing paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse leakage current | 0.003 nA typ. @ VR = 75 V, Tj = 25 °C - enables stable biasing in high-Z analog nodes |
| Reverse recovery time | 0.8 µs typ. - supports switching frequencies up to ~500 kHz in clamp and snubber circuits |
| Repetitive peak reverse voltage | 85 V - suitable for 12 V/24 V automotive bus transient suppression (ISO 7637-2 Level 5) |
| Forward voltage | 1.1 V max. @ IF = 50 mA - minimizes conduction loss in low-power signal routing |
| Junction-to-ambient thermal resistance | 450 K/W - defines derating curve for continuous IF vs. Tamb (Fig. 1: 200 mA @ 25 °C ambient) |
| Peak forward surge current | 4 A @ tp = 1 µs - withstands ESD-induced transients without degradation |
| Diode capacitance | 2 pF @ VR = 0 V, f = 1 MHz - preserves signal integrity in RF detector and timing circuits |
Pinout & Package
The BAS416-QZ is housed in a surface-mount SOD323 plastic package measuring 1.7 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch and standard FR4-compatible footprint (Fig. 7–9).

|---|---|
| AEC-Q101 qualification | Validated for automotive underhood applications including engine control units and body electronics |
| Low leakage at high temperature | 3 nA typ. @ VR = 75 V, Tj = 150 °C - maintains signal fidelity in hot-cavity environments |
| Controlled reverse recovery | trr = 0.8 µs typ. with <3 µs max. - reduces switching noise in mixed-signal PCB layouts |
| SOD323 thermal performance | Ptot = 250 mW @ Tamb ≤ 25 °C on FR4 - enables compact placement near heat-sensitive ICs |
Applications
| Automotive Sensor Biasing | ESD Protection Diode |
|---|---|
Use Scenario: Providing stable DC bias to piezoresistive pressure sensors in engine manifolds. IC Role / Device Role / Timing Role: Low-leakage voltage reference clamp preventing sensor offset drift. Use Value: 0.003 nA leakage ensures <1 µV error contribution at 1 MΩ sensor impedance. |
Use Scenario: Protecting CAN transceiver I/O pins against ISO 10605 ESD events. IC Role / Device Role / Timing Role: Fast-turnoff shunt path diverting transient current away from sensitive inputs. Use Value: 0.8 µs trr limits clamping duration, reducing risk of latch-up in adjacent logic. |
| Sample-and-Hold Input Clamp | Power Sequencing Diode |
Use Scenario: Preventing op-amp input overvoltage during ADC sampling in battery management systems. IC Role / Device Role / Timing Role: Precision voltage limiter with minimal parasitic capacitance. Use Value: 2 pF capacitance avoids phase shift in >1 MHz sampling clock paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSVRBAS416WT1G | Same SOD323 package, 5 pA IR typ. @ 75 V - 67% higher leakage than BAS416-QZ | Acceptable for non-critical biasing but not recommended for <100 nA leakage budgets | Select when cost sensitivity outweighs ultra-low-leakage requirement |
| Vishay VS-2EDH02HM3/85A | SOD-123 package, 100 V VRRM, 1.5 V VF @ 50 mA - larger footprint, higher forward drop | Preferred for higher-voltage industrial rails but unsuitable for space-constrained automotive PCBs | Choose only if 100 V rating and board area margin are primary constraints |
Compared with NSVRBAS416WT1G and VS-2EDH02HM3/85A, the BAS416-QZ delivers the lowest verified leakage (0.003 nA) in the smallest standardized SMD package, making it optimal for automotive sensor interfaces where leakage-induced offset and board real estate are co-constrained.

FAQ
What is the maximum continuous forward current for BAS416-QZ at 85 °C ambient?
Per Figure 1 in the datasheet, the maximum permissible continuous forward current is approximately 120 mA at Tamb = 85 °C when mounted on an FR4 PCB with single-sided copper. This derating accounts for the device's 450 K/W Rth(j-a) and 150 °C Tj limit, ensuring safe operation without exceeding junction temperature.
Is BAS416-QZ suitable for bidirectional ESD protection?
No - BAS416-QZ is a unidirectional diode with defined anode and cathode terminals (Pin 2 = A, Pin 1 = K). For bidirectional ESD protection, a dual-diode array such as the PESD5V0S1BA (SOD323) would be required. BAS416-QZ functions only as a cathode-to-rail or anode-to-rail clamp depending on orientation.
Does the 3 pA leakage specification apply at elevated temperature?
Yes - the datasheet specifies 3 nA typical reverse current at VR = 75 V and Tj = 150 °C (Figure 4), which is 1000× higher than the 0.003 nA value at 25 °C. Designers must use the 3 nA figure for worst-case leakage analysis in underhood applications.
Can BAS416-QZ replace BAS16 in existing designs?
Only with validation - while both are SOD323 switching diodes, BAS416-QZ offers 100× lower leakage (0.003 nA vs. 0.3 nA typ.) and faster trr (0.8 µs vs. 4 ns), but its higher VF (1.1 V vs. 0.89 V) may affect low-voltage logic interface margins. Layout and thermal verification are required before substitution.
