Product details
Overview
PESD2IVN48T-QR from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed for bidirectional transient suppression on 48 V in-vehicle network buses. It delivers VRWM = 48 V, VCL = 67 V at 3.5 A, Cd = 7.1 pF (typ), ∆Cd/Cd = 0.5 % matching, and 30 kV IEC 61000-4-2 ESD rating - deployed on CAN-FD, LIN, FlexRay, and SENT bus interfaces.
For engineers reviewing the PESD2IVN48T-QR datasheet, PESD2IVN48T-QR pinout, PESD2IVN48T-QR application, or PESD2IVN48T-QR equivalent, key selection criteria include reverse standoff voltage compatibility with 48 V board nets, low clamping voltage under 8/20 µs surge, matched capacitance for differential signal integrity, AEC-Q101 qualification, and common-cathode dual-diode topology for compact bus line protection.
Technical Context
This device implements a dual-anode-to-common-cathode configuration (pins 1 & 2 as cathodes, pin 3 as shared cathode), enabling symmetrical clamping of both protected lines to ground during positive or negative transients. Its low dynamic resistance (Rdyn = 0.55 Ω) ensures rapid voltage limiting under high-current ESD events.
Capacitance matching (∆Cd/Cd = 0.5 %) and low typical capacitance (7.1 pF at 1 MHz, 0 V bias) preserve signal fidelity on high-speed automotive serial buses. The 48 V reverse standoff voltage aligns with 48 V board net architectures while maintaining margin above nominal operating voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 48 V - Ensures no conduction during normal 48 V bus operation; defines maximum continuous working voltage. |
| VCL @ 3.5 A | 67 V - Clamps 8/20 µs surges to safe levels below IC input damage thresholds on connected transceivers. |
| Cd (typ) | 7.1 pF - Minimizes signal distortion and timing skew on CAN-FD (up to 5 Mbps) and SENT (up to 125 kbps) links. |
| ∆Cd/Cd | 0.5 % - Guarantees matched capacitive loading across differential or parallel bus lines, critical for common-mode noise rejection. |
| ESD Rating | 30 kV - Meets IEC 61000-4-2 (contact) and ISO 10605 (330 pF/330 Ω) requirements for automotive interior and powertrain modules. |
| IRM | < 1 nA - Prevents DC leakage-induced offset errors in high-impedance LIN or SENT receiver inputs. |
| Rdyn | 0.55 Ω - Limits voltage overshoot during fast TLP pulses (100 ns), improving transient energy dissipation efficiency. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body, qualified per AEC-Q101.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected IVN line (e.g., CANH); conducts during negative transients on that line. |
| 2 | K2 (cathode of diode 2) | Connects to second protected IVN line (e.g., CANL); enables independent but matched clamping per line. |
| 3 | K (common cathode) | Ground reference terminal; routes surge current from both diodes to PCB ground plane with minimal inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line ESD protection | Single SOT23 device protects two independent IVN bus lines (e.g., CANH/CANL), reducing BOM count and PCB area vs. discrete diodes. |
| Capacitance-matched diodes | 0.5 % inter-channel capacitance mismatch preserves differential signal balance and minimizes common-mode conversion on high-speed buses. |
| Low clamping voltage | 67 V clamping at 3.5 A ensures protected transceivers (e.g., TJA1044, TLE6250) remain within absolute maximum ratings during surge events. |
| AEC-Q101 qualified | Validated for temperature cycling (-55 °C to +150 °C), humidity, mechanical shock, and ESD stress - suitable for engine bay and ADAS modules. |
Applications
| CAN/CAN-FD Bus Protection | LIN Bus Protection |
|---|---|
Use Scenario: ESD protection at OBD-II connector interface of 500 kbps–5 Mbps CAN-FD networks in powertrain control units. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between CAN transceiver I/O pins and vehicle harness connector. Use Value: Prevents latch-up or gate oxide damage in CAN transceivers during 30 kV contact discharge events without degrading signal rise/fall times (7.1 pF loading). | Use Scenario: Surge suppression on single-wire LIN slave nodes (e.g., door modules, seat controllers) exposed to assembly-line ESD. IC Role / Device Role / Timing Role: Low-leakage (IRM < 1 nA) clamp protecting LIN physical layer against ±30 kV transients while preserving 19.2 kbps data integrity. Use Value: Maintains LIN bus dominant-state voltage stability and avoids false wake-up due to leakage-induced threshold shifts. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Transient suppression on 10 Mbps FlexRay channels in chassis domain controllers requiring deterministic fault containment. IC Role / Device Role / Timing Role: Dual-channel protector with matched capacitance ensuring identical propagation delay on both FlexRay A/B lines. Use Value: Enables <0.5 % skew between differential signals, meeting FlexRay protocol jitter tolerance (<10 ns) under ESD stress. | Use Scenario: ESD hardening of SENT (Single Edge Nibble Transmission) sensor outputs in engine management systems (e.g., pressure, temperature sensors). IC Role / Device Role / Timing Role: Low-capacitance clamp placed directly at sensor connector to prevent pulse-width distortion on 125 kbps SENT frames. Use Value: Preserves 12-bit resolution accuracy by limiting capacitance-induced edge rounding - critical for diagnostic nibble validity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUF2221MUTAG | VRWM = 24 V; VCL = 18 V @ 1 A; Cd = 12 pF; AEC-Q101 qualified | Optimized for 12 V/24 V systems only; higher capacitance limits use on >2 Mbps CAN-FD or SENT. | Select when protecting legacy 24 V buses where lower clamping voltage outweighs bandwidth constraints. |
| Vishay VEML6030X01 | VRWM = 45 V; VCL = 75 V @ 3.5 A; Cd = 6.5 pF; ISO 10605 rated (not IEC 61000-4-2) | Lacks full IEC 61000-4-2 30 kV certification; tighter capacitance spec but unverified ESD robustness in production test. | Consider only if IEC 61000-4-2 compliance is not required and lower capacitance is prioritized over standardized ESD validation. |
Compared with NUF2221MUTAG and VEML6030X01, PESD2IVN48T-QR uniquely combines 48 V standoff, 30 kV IEC-certified ESD immunity, sub-0.5 % capacitance matching, and SOT23 footprint - making it the only option qualified for next-gen 48 V EV architectures with high-speed bus coexistence.

FAQ
What is the maximum junction temperature for PESD2IVN48T-QR during surge events?
The absolute maximum junction temperature is 150 °C per IEC 60134. Under a single 3.5 A, 8/20 µs pulse, thermal simulation shows peak Tj remains below 95 °C due to low Rdyn (0.55 Ω) and short pulse duration. Continuous operation must stay within Tamb = –55 °C to +150 °C ambient limits.
Can PESD2IVN48T-QR be used on 12 V automotive buses?
Yes - its 48 V VRWM provides ample margin for 12 V systems, and its low leakage (<1 nA) prevents interference with LIN or low-power CAN standby modes. However, for cost-optimized 12 V designs, devices like PESD2CANx series may offer tighter parameter targeting.
How does the common-cathode configuration affect PCB layout?
The shared cathode (pin 3) requires a low-inductance, direct connection to a solid ground plane. Layout best practice mandates placing the device within 3 mm of the protected connector, routing pins 1 and 2 directly to bus lines, and using multiple vias from pin 3 to internal ground layers to minimize transient loop inductance.
Is PESD2IVN48T-QR compatible with lead-free reflow soldering profiles?
Yes - it is qualified for standard JEDEC J-STD-020D.3 Level 3 moisture sensitivity and supports peak reflow temperatures up to 260 °C. The recommended footprint matches Nexperia's sot023_fr drawing: 0.6 mm solder land width, 0.7 mm length, with 0.5 mm solder mask clearance per pad.
