Product details
Overview
1PS76SB40,135 from Nexperia is a general-purpose Schottky diode in SOD323 (SC-76) package, designed for ultra-high-speed switching and voltage clamping. It delivers 40 V reverse voltage rating, 120 mA forward current capability, 380 mV forward voltage at 1 mA, 5 pF capacitance at 0 V, and 1 µA reverse leakage at 30 V - enabling compact, low-loss signal path protection in space-constrained DC-DC and interface circuits.
For engineers reviewing the 1PS76SB40,135 datasheet, 1PS76SB40,135 pinout, 1PS76SB40,135 application, or 1PS76SB40,135 equivalent, key selection criteria include its low VF/low Cd trade-off, SOD323 footprint compatibility, thermal resistance of 450 K/W on FR4, and non-automotive qualification status per revision v.12 (Jan 2023).
Technical Context
This Schottky diode leverages a metal-semiconductor junction to achieve fast recovery (no minority carrier storage), enabling operation beyond 100 MHz in clamping and sampling applications. Its 40 V VR rating supports use in 24 V and 36 V industrial bus interfaces without derating at 25 °C.
The device exhibits temperature-dependent VF (0.38 V @ 25 °C → ~0.6 V @ 125 °C) and IR (1 µA @ 25 °C → ~10 µA @ 125 °C), requiring thermal-aware layout in high-ambient environments. Junction-to-ambient thermal resistance of 450 K/W assumes single-sided copper FR4 mounting with standard SOD323 footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 40 V - maximum blocking voltage before breakdown; suitable for 24 V rail clamping with 67% margin. |
| IF (Forward Current) | 120 mA continuous - supports logic-level signal routing and low-power bias networks. |
| VF (Forward Voltage) | 380 mV @ 1 mA - minimizes conduction loss in low-current sensing and level-shifting paths. |
| Cd (Capacitance) | 5 pF @ 0 V, 1 MHz - enables <1 ns rise-time preservation in RF detector and high-speed data line clamping. |
| IR (Reverse Leakage) | 1 µA @ 30 V, 25 °C - ensures stable DC bias integrity in precision reference and sample-hold circuits. |
| Rth(j-a) | 450 K/W - defines thermal rise under 120 mA DC: ~54 °C rise above ambient on standard FR4 PCB. |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to lower-potential node; marking bar aligns with this pin for visual polarity verification during placement. |
| 2 | Anode (A) | Connected to higher-potential node; current flows from Pin 2 to Pin 1 when forward-biased. |
Key Features
| Feature | Design Value |
|---|---|
| High switching speed | No minority carrier storage → sub-nanosecond recovery; preserves signal edge integrity in >100 MHz pulse applications. |
| Low leakage current | 1 µA @ 30 V enables stable DC bias in high-impedance feedback networks and sensor conditioning stages. |
| Low capacitance | 5 pF allows integration into 50 Ω RF paths without significant impedance mismatch or bandwidth degradation. |
| High breakdown voltage | 40 V VR rating supports use in 24 V industrial I/O protection without series resistors or voltage dividers. |
Applications
| USB 2.0 ESD Protection | DC-DC Converter Output Clamp |
|---|---|
|
Use Scenario: Bidirectional transient suppression on USB D+/D− lines prior to PHY input. IC Role / Device Role: Low-capacitance shunt clamp limiting voltage spikes to <3.6 V while preserving 480 Mbps signal integrity. Use Value: 5 pF capacitance avoids signal rise-time degradation; 380 mV VF ensures minimal DC offset in idle state. |
Use Scenario: Snubberless flyback output rectification in isolated 5 V/12 V auxiliary supplies. IC Role / Device Role: Freewheeling diode conducting peak currents up to 120 mA with minimal conduction loss. Use Value: 380 mV VF reduces power dissipation vs. silicon diodes; 40 V VR covers reflected transients in 12 V designs. |
| Logic-Level Signal Clamping | Microcontroller GPIO Protection |
|
Use Scenario: Input clamping for 3.3 V microcontroller pins interfacing with 5 V peripherals. IC Role / Device Role: Forward-biased clamp limiting input voltage to VDD + 0.38 V during overvoltage events. Use Value: Low VF prevents latch-up trigger; 1 µA leakage avoids loading high-Z analog inputs. |
Use Scenario: I/O pin protection against ESD and inductive kickback in industrial control modules. IC Role / Device Role: Reverse-biased barrier absorbing ±8 kV HBM transients while maintaining low standby current. Use Value: 40 V VR withstands common-mode surges; SOD323 footprint fits tight spacing around MCU packages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS40-04,115 | Same SOD323 package; 40 V VR, but VF = 440 mV @ 1 mA - 60 mV higher forward drop. | Higher VF increases conduction loss in low-current bias paths; otherwise identical clamping function. | Select when legacy design uses BAS40-04 footprint and minor VF increase is acceptable. |
| 1PS79SB40,115 | Same electrical specs (40 V/120 mA/380 mV/5 pF); differs only in marking code (S5 vs S4) and revision history. | No functional difference; qualified to same non-automotive spec per v.11 release (Aug 2022). | Drop-in replacement where 1PS79SB40 is already approved in BOM; identical thermal and electrical behavior. |
Compared with BAS40-04,115, 1PS76SB40,135 offers lower VF for reduced power loss; versus 1PS79SB40,115, it shares identical performance but reflects updated revision control and packaging traceability per Jan 2023 release.

FAQ
Is 1PS76SB40,135 qualified for automotive applications?
No. Per revision v.12 (January 2023), this part is explicitly designated as non-automotive qualified. Nexperia states that automotive alternatives must be selected from their -Q qualified product line, such as 1PS76SB40-Q. Use in automotive systems voids warranty and requires independent qualification by the customer.
What is the maximum pulsed forward current rating?
The non-repetitive peak forward current (IFSM) is 200 mA for tp ≤ 10 ms at Tj(init) = 25 °C. This rating applies to short-duration transients like ESD or inductive kickback, not sustained operation. Continuous IF remains limited to 120 mA per absolute maximum ratings.
How does thermal resistance change with PCB copper area?
Rth(j-a) = 450 K/W is measured on FR4 with single-sided copper and standard SOD323 footprint. Increasing copper area (e.g., thermal pads or internal planes) can reduce Rth(j-a) by 20–40%, but no official characterization is provided beyond the stated test condition.
Can 1PS76SB40,135 replace BAS40 in existing designs?
Yes, with verification. Both share SOD323 package, 40 V VR, and 120 mA IF, but 1PS76SB40 has lower VF (380 mV vs 440 mV for BAS40-04). Layout and solder profile are identical; confirm system-level timing and leakage margins remain within spec after substitution.
