Product details
Overview
1PS88SB48 from Nexperia is a general-purpose quadruple Schottky diode in SOT363 (TSSOP6) package, configured as two independent dual-anode/common-cathode pairs (A1/A2–K1:K2 and A3/A4–K3:K4), with 40 V reverse voltage rating, 120 mA forward current capability, and 380 mV typical forward voltage at 1 mA - used for ultra high-speed switching and voltage clamping in automotive signal conditioning circuits.
For engineers reviewing the 1PS88SB48 datasheet, 1PS88SB48 pinout, 1PS88SB48 application, or 1PS88SB48 equivalent, key selection criteria include its AEC-Q101 qualification, low 5 pF capacitance at 0 V, 1 µA max reverse leakage at 30 V, dual-common-cathode topology, and thermal resistance of 416 K/W on FR4 PCB - critical for compact automotive interface protection designs.
Technical Context
This discrete Schottky diode integrates four junctions in a single 6-pin surface-mount package with two electrically isolated dual-diode sections. Each section shares a common cathode terminal (pins 3 and 6), enabling independent clamping or steering functions without inter-section coupling.
Its AEC-Q101 qualification confirms operation across −65 °C to +150 °C ambient, supported by 200 mA non-repetitive peak forward current and 150 °C maximum junction temperature - making it suitable for under-hood automotive electronics where thermal robustness and transient immunity are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports clamping of transients up to ISO 7637-2 Pulse 1/2a levels in 12 V automotive systems. |
| Forward Voltage (VF) | 380 mV @ 1 mA - enables low-loss signal-level clamping with minimal DC offset in high-impedance sensing paths. |
| Reverse Leakage (IR) | 1 µA @ 30 V - ensures negligible standby current in always-on vehicle modules like CAN wake-up receivers. |
| Diode Capacitance (Cd) | 5 pF @ 0 V, 1 MHz - preserves signal integrity above 100 MHz in high-speed data line protection (e.g., LIN, SENT). |
| Thermal Resistance (Rth(j-a)) | 416 K/W - defines power derating on standard FR4 PCB; limits continuous dissipation to ~290 mW at 25 °C ambient. |
| Junction Temperature (Tj) | 150 °C - allows sustained operation in engine control unit (ECU) proximity without active cooling. |
Pinout & Package
Package: SOT363 (TSSOP6), 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, plastic surface-mount package with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first Schottky diode in pair sharing cathode pin 6 (K1:K2). |
| 2 | Anode (Diode 2) | Second input node tied to same common cathode (pin 6); enables dual-input clamping to single rail. |
| 3 | Common Cathode (Diodes 3 & 4) | Shared output node for second dual-diode section; electrically isolated from pin 6. |
| 4 | Anode (Diode 3) | Input node for third Schottky diode in pair sharing cathode pin 3 (K3:K4). |
| 5 | Anode (Diode 4) | Fourth input node tied to same common cathode (pin 3); supports dual-rail clamping architecture. |
| 6 | Common Cathode (Diodes 1 & 2) | Shared output node for first dual-diode section; enables compact dual-signal protection per cathode net. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including HTGB, HTRB, and temperature cycling - eliminates requalification effort for Tier 1 ECU designs. |
| Low 5 pF capacitance | Minimizes signal distortion on high-frequency lines (e.g., sensor analog outputs, clock distribution), preserving rise/fall times below 1 ns. |
| Dual common-cathode topology | Reduces PCB footprint vs. discrete dual-diode solutions; enables two independent clamping functions with only three nets (two anode groups + two cathodes). |
| 380 mV VF at 1 mA | Enables effective clamping of logic-level signals (e.g., 3.3 V microcontroller I/O) without forward conduction during normal operation. |
Applications
| Automotive LIN Bus Protection | Engine Control Unit (ECU) Signal Clamping |
|---|---|
Use Scenario: Protecting LIN transceiver pins against load dump and inductive switching transients in body control modules. IC Role / Device Role / Timing Role: Discrete voltage clamp placed between LIN bus and transceiver I/O, conducting only during overvoltage events. Use Value: 40 V VR rating absorbs ISO 7637-2 Pulse 1 (−100 V) via external series impedance while 5 pF capacitance avoids signal jitter on 19.2 kbaud bus. |
Use Scenario: Clamping analog sensor inputs (e.g., MAP, TPS) in engine management systems exposed to alternator ripple and relay kickback. IC Role / Device Role / Timing Role: Passive front-end protection element shunting transients to ground or supply rail before signal conditioning amplifiers. Use Value: Dual-common-cathode structure allows simultaneous clamping of two sensor channels to separate rails using one device, reducing BOM count by 50% vs. singles. |
| Infotainment System ESD Suppression | ADAS Camera Interface Protection |
Use Scenario: I/O line protection for USB, UART, or I²C interfaces in head units subjected to human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Low-capacitance shunt path that remains non-conductive during normal signaling but clamps >±8 kV HBM pulses. Use Value: 1 µA IR at 30 V prevents DC loading of pull-up resistors; 380 mV VF ensures clamping threshold stays below logic-high thresholds of 3.3 V MCUs. |
Use Scenario: Protecting high-speed MIPI CSI-2 differential pairs in surround-view camera modules from cable discharge events. IC Role / Device Role / Timing Role: Per-line unidirectional clamp referenced to IOVDD, placed adjacent to connector to minimize stub length. Use Value: 416 K/W Rth(j-a) allows localized heat dissipation during repetitive ESD strikes without thermal runaway, validated per AEC-Q101 HBM testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1PS79SB40,115 | Lower VR = 30 V; identical SOT363 package and pinout; VF = 410 mV @ 1 mA. | Not rated for 40 V transients; unsuitable for 24 V commercial vehicle systems or higher-energy load dump scenarios. | Select only when system max transient voltage is ≤30 V and lower forward drop is not required. |
| RB050M-40TF | Single dual-diode (not quadruple); TO-220FP package; VR = 40 V; VF = 550 mV @ 1 A. | Requires two devices and larger board area to replicate quad functionality; higher VF increases clamping voltage under surge. | Use only if through-hole mounting is mandatory and thermal mass outweighs space constraints. |
Compared with 1PS79SB40,115 and RB050M-40TF, the 1PS88SB48 uniquely delivers AEC-Q101-qualified 40 V clamping in a space-optimized quad configuration with lowest VF and Cd - essential for next-generation compact, high-channel-count automotive ECUs.

FAQ
Is the 1PS88SB48 suitable for bidirectional ESD protection?
No - the 1PS88SB48 is a unidirectional Schottky diode array with anodes and common cathodes. It provides clamping only from signal line to cathode reference (e.g., ground or supply). For bidirectional protection, external series resistors and complementary diodes or dedicated TVS arrays are required.
What is the maximum allowable soldering temperature profile for SOT363 packaging?
The 1PS88SB48 follows JEDEC J-STD-020D.2 for moisture sensitivity level 1. Peak reflow temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. Wave soldering requires preheating to 100–150 °C and contact time <5 s at 260 °C max.
Can pins 3 and 6 be connected together to create a single 4-anode common-cathode configuration?
No - pins 3 (K3:K4) and 6 (K1:K2) are electrically isolated internal cathodes. Connecting them externally violates the device's internal construction and may cause uneven current sharing, thermal imbalance, or premature failure under surge conditions.
How does the 1 µA reverse leakage at 30 V impact battery-drain-critical always-on circuits?
At 1 µA per diode section (two sections total), worst-case leakage is 2 µA - well within typical automotive "keep-alive" current budgets (<100 µA). This enables use in door module wake-up receivers and CAN transceivers without compromising sleep-mode battery life over 10+ years.
