Product details
Overview
BAS32L,115 from Nexperia is a single high-speed switching diode in a hermetically sealed glass SOD80C surface-mount package, designed for fast signal routing and polarity protection. It delivers trr ≤4 ns reverse recovery time, VRRM = 100 V, IFRM = 450 mA, and VF = 1000 mV at IF = 100 mA - enabling use in compact DC-DC converter flyback snubbers and USB port reverse-polarity circuits.
For engineers reviewing the BAS32L,115 datasheet, BAS32L,115 pinout, BAS32L,115 application, or BAS32L,115 equivalent, key selection criteria include verified 4 ns trr performance under RL = 100 Ω test conditions, cathode-marked SOD80C footprint compatibility, and thermal resistance Rth(j-a) = 350 K/W on FR4 PCBs.
Technical Context
The BAS32L,115 employs planar silicon technology to achieve sub-5 ns reverse recovery with low junction capacitance (Cd = 2 pF at VR = 0 V, f = 1 MHz). Its structure supports repetitive 450 mA peak forward current and withstands 100 V repetitive reverse voltage without degradation.
Tested per IEC 60134 absolute maximum ratings, it operates across −65 °C to +200 °C ambient and junction temperatures, with forward recovery voltage limited to 2.5 V and reverse leakage held to ≤5 μA at VR = 75 V and Tj = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| trr | 4 ns - enables >100 MHz switching in clamping and sampling circuits |
| VRRM | 100 V - supports 48 V industrial bus transient suppression |
| IFRM | 450 mA - sustains pulsed current in synchronous rectifier auxiliary paths |
| VF @ 100 mA | 1000 mV - limits conduction loss to <100 mW in 5 V logic-level clamp designs |
| Cd @ 0 V | 2 pF - minimizes capacitive loading on RF detector inputs |
| Rth(j-a) | 350 K/W - requires no heatsink on standard FR4 with 200 mA DC operation |
Pinout & Package
Hermetically sealed glass SOD80C package (3.7 mm × 1.6 mm × 0.3 mm), with axial leads formed into gull-wing SMD terminals. Cathode identified by black band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to ground or lower-potential node in reverse polarity protection |
| 2 | Anode | Connected to input power rail; conducts when forward-biased above ~0.7 V |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | 4 ns trr ensures minimal dead-time distortion in 50–100 MHz clock distribution networks |
| Low forward voltage | 1000 mV at 100 mA reduces power dissipation in battery-powered load-switching paths |
| Small SMD footprint | SOD80C outline fits 2.3 mm × 4.3 mm reflow land pattern, saving board space vs. DO-35 |
| Hermetic glass seal | Prevents moisture ingress and parameter drift in humid industrial environments |
Applications
| USB Power Input Protection | DC-DC Converter Snubber |
|---|---|
Use Scenario: Preventing damage from reversed USB cable insertion in portable chargers and hubs. IC Role / Device Role / Timing Role: Unidirectional current gate placed between VBUS and system input, blocking reverse current flow. Use Value: 100 V VRRM withstands hot-swap transients; 4 ns trr avoids latch-up during rapid polarity reversal. |
Use Scenario: Suppressing voltage spikes across MOSFETs in 300 kHz buck converters. IC Role / Device Role / Timing Role: Fast-recovery clamp diode in RCD snubber network across primary switch. Use Value: 2 pF capacitance prevents resonance with snubber resistor; 450 mA IFRM handles peak energy dump pulses. |
| RF Detector Clamping | Logic-Level Signal Steering |
Use Scenario: Protecting ADC inputs of 2.4 GHz WiFi front-end RSSI detectors from overvoltage. IC Role / Device Role / Timing Role: Low-capacitance clamp limiting RF envelope voltage to ±0.7 V. Use Value: 2 pF Cd avoids detuning 50 Ω matching networks; 4 ns trr preserves pulse fidelity up to 200 MHz. |
Use Scenario: Isolating multiple microcontroller GPIOs sharing a common interrupt line. IC Role / Device Role / Timing Role: OR-ing diode enabling wired-AND logic without contention. Use Value: 1000 mV VF ensures clean TTL/CMOS threshold crossing; SOD80C size allows dense 0.5 mm pitch routing. |
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 |
|---|---|---|---|
| BAS116,115 | trr = 4 ns (same), but VF = 1250 mV @ 100 mA; Cd = 2.5 pF | Higher forward drop increases conduction loss in low-voltage (<3.3 V) rails | Select when higher VRRM (100 V) and identical speed are required, but VF tolerance >1.2 V is acceptable |
| 1N4148W,115 | trr = 4 ns (same), VRRM = 100 V, but IFRM = 300 mA and Rth(j-a) = 400 K/W | Lower surge rating limits use in high-dI/dt snubbers; higher thermal resistance demands derating above 150 mA | Choose only for cost-sensitive, non-derated 200 mA applications where thermal margin is available |
Compared with BAS116,115 and 1N4148W,115, the BAS32L,115 uniquely balances 450 mA IFRM, 1000 mV VF, and 350 K/W thermal resistance - making it optimal for thermally constrained, medium-current switching nodes requiring consistent sub-5 ns timing.

FAQ
What is the maximum continuous forward current for BAS32L,115?
The maximum continuous forward current (IF) is 200 mA at Tamb = 25 °C, derating linearly to zero at +200 °C ambient per the published derating curve. This rating assumes mounting on FR4 PCB with single-sided copper and standard footprint, not forced-air or heatsink cooling.
Does BAS32L,115 meet automotive AEC-Q200 requirements?
No - the BAS32L,115 is not AEC-Q200 qualified. The datasheet explicitly states it is a non-automotive qualified product, with no qualification testing performed per automotive stress or reliability standards. Use in automotive applications is at the customer's sole risk.
How is cathode identification implemented on the SOD80C package?
The cathode is marked by a distinct black band located at terminal 1 end of the glass body. This aligns with the pinning diagram in the datasheet and matches the graphic symbol showing 'k' at pin 1. No laser marking or alphanumeric code is used - only the physical band.
Can BAS32L,115 be used in place of 1N4148 in high-frequency circuits?
Yes - with identical 4 ns trr and 100 V VRRM, the BAS32L,115 offers superior IFRM (450 mA vs. 300 mA) and lower thermal resistance (350 K/W vs. 400 K/W), making it a direct functional upgrade in most 1N4148 applications above 200 mA or in thermally tight layouts.
