Product details
Overview
BAS32L,135 from Nexperia is a single high-speed switching diode fabricated in planar technology and housed in a hermetically sealed glass SOD80C surface-mount package. 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 polarity protection circuits.
For engineers reviewing the BAS32L,135 datasheet, BAS32L,135 pinout, BAS32L,135 application, or BAS32L,135 equivalent, key selection criteria include verified 4 ns trr performance under IF = 10 mA → IR = 10 mA switching conditions, cathode-marked SOD80C footprint compatibility, and thermal resistance Rth(j-a) = 350 K/W on FR4 PCBs.
Technical Context
The BAS32L,135 employs a planar-diffused silicon junction optimized for rapid carrier recombination, achieving sub-4 ns reverse recovery by minimizing minority-carrier storage time. Its structure supports repetitive 450 mA peak forward current with low 1000 mV forward drop at 100 mA.
Designed for operation up to Tj = 200 °C, it maintains IR ≤5 μA at VR = 75 V and Tj = 25 °C, while diode capacitance remains ≤2 pF at VR = 0 V and f = 1 MHz - critical for RF detector and high-frequency clamp applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| trr | 4 ns maximum - enables >100 MHz switching in pulse shaping and sample-and-hold circuits |
| VRRM | 100 V - supports 48 V industrial bus transient suppression without derating |
| IFRM | 450 mA - sustains pulsed currents in synchronous rectifier auxiliary paths |
| VF @ 100 mA | 1000 mV - limits conduction loss to <100 mW in 5 V logic-level clamping |
| Cd @ 0 V | 2 pF - minimizes signal distortion in 2.4 GHz ISM-band RF detector front-ends |
| Rth(j-a) | 350 K/W - requires no heatsink on standard FR4 with 200 mA DC bias |
| IR @ 75 V | 5 μA max - ensures leakage-induced offset <1 μV in precision op-amp input protection |
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; marking band denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to load return or ground reference; polarity-sensitive for reverse protection |
| 2 | Anode | Connected to input supply rail; carries forward current during conduction phase |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤4 ns verified under IF/IR = 10 mA transition - reduces dead-time losses in 500 kHz SMPS |
| Low forward voltage | VF = 1000 mV at 100 mA - cuts power dissipation by 30% vs. BAS21 in 3.3 V rail clamps |
| Hermetic glass sealing | Prevents moisture ingress and parameter drift over 15-year field life in outdoor telecom enclosures |
| Small SMD footprint | SOD80C outline fits 2.3 mm × 4.3 mm reflow land pattern - saves 40% board area vs. DO-35 |
Applications
| USB Power Delivery Polarity Protection | DC-DC Converter Snubber Diode |
|---|---|

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 |
|---|---|---|---|
| BAS21,113 | trr = 50 ns; VRRM = 250 V; VF = 1250 mV @ 100 mA | Higher voltage rating but 12× slower recovery - unsuitable for >1 MHz switching | Select only when VRRM > 100 V is mandatory and speed is secondary |
| 1N4148W-7-F | trr = 4 ns; VRRM = 100 V; VF = 1000 mV @ 10 mA (not rated at 100 mA) | Same speed but derated forward current - limited to 150 mA continuous in FR4 layout | Prefer for low-current signal routing; avoid in power-path applications above 200 mA |
Compared with BAS21,113 and 1N4148W-7-F, the BAS32L,135 uniquely balances 4 ns trr, 450 mA IFRM, and 1000 mV VF at 100 mA - making it the only option qualified for both high-frequency switching and moderate-power clamping in space-constrained designs.

FAQ
What is the maximum continuous forward current for BAS32L,135 on a standard FR4 PCB?
The maximum continuous forward current is 200 mA under ambient conditions per Table 1, based on thermal derating from Ptot = 500 mW and Rth(j-a) = 350 K/W. At Tamb = 25 °C, this allows sustained 200 mA conduction without exceeding Tj = 100 °C.
Does BAS32L,135 meet lead-free reflow requirements?
Yes - the SOD80C package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 10 seconds. The glass body and tin-plated terminations ensure reliable wetting and intermetallic formation during standard Pb-free profiles.
How is cathode identification implemented on the BAS32L,135 package?
A distinct black marking band is applied adjacent to Pin 1 (cathode) on the glass body, visible under 10× magnification. This aligns with the graphic symbol in Figure 2 and matches the "k" terminal designation in the pinning diagram - confirming unambiguous polarity orientation during automated placement.
Can BAS32L,135 be used in automotive applications?
No - the device is not AEC-Q101 qualified and lacks automotive-specific stress testing or qualification documentation. Nexperia explicitly states non-automotive status in Section 13.3 of the datasheet; use in vehicle systems voids warranty and introduces unmitigated reliability risk.
