Product details
Overview
TDZ4V3J,115 from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation and transient suppression in low-power circuits. It delivers a nominal Zener voltage of 4.3 V (min 4.21 V, max 4.39 V) at 5 mA, with differential resistance ≤600 Ω, total power dissipation up to 500 mW, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TDZ4V3J,115 datasheet, TDZ4V3J,115 pinout, TDZ4V3J,115 application, or TDZ4V3J,115 equivalent, key selection criteria include Zener voltage tolerance, low differential resistance for stable clamping, thermal resistance (Rth(j-a) = 250 K/W), non-repetitive peak reverse power (180 W), and SOD323F footprint compatibility in space-constrained PCB layouts.
Technical Context
This Zener diode operates as a two-terminal voltage reference and overvoltage clamp, leveraging avalanche breakdown at its specified 4.3 V working voltage. Its temperature coefficient is −3.5 mV/K (typical), ensuring predictable drift across −55 °C to +150 °C ambient range.
Designed for surface-mount reliability, it features a cathode-marked SOD323F package with 16 mm² copper pad per JEDEC-standard thermal test condition, enabling effective heat dissipation despite its 0.8 mm × 1.35 mm footprint. Reverse leakage remains ≤3 µA at VR = 1 V, supporting low-quiescent-current biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.21 V to 4.39 V at IZ = 5 mA - tight 4.3 V nominal regulation with ±2% tolerance for stable reference generation |
| Differential Resistance (rdif) | ≤600 Ω at IZ = 5 mA - low impedance ensures minimal voltage shift under load variation |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Reverse Power (PZSM) | 180 W for tp ≤ 100 µs - supports robust ESD/line-transient suppression without failure |
| Reverse Current (IR) | ≤3 µA at VR = 1 V - enables low-leakage bias networks and high-impedance sensing interfaces |
| Junction Temperature (Tj) | −55 °C to +150 °C - validated operating range for under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
SOD323F (SC-90) plastic surface-mounted package: ultra-compact 0.8 mm × 1.35 mm outline with flat leads, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode | Connected to ground or lower-potential rail; forms the reference return path for Zener conduction |
Key Features
| Feature | Design Value |

| AEC-Q101 Qualification | Validated for automotive applications including engine control units and body electronics - no derating required for qualified use cases |
| Small Outline Package (SOD323F) | 0.8 mm × 1.35 mm footprint saves >60% board area vs. SOD123 - ideal for wearables and compact ECUs |
| High Surge Withstand | 180 W non-repetitive peak power (100 µs pulse) - protects downstream ICs from ISO 7637-2 Pulse 1/2a transients |
| Controlled Temperature Coefficient | −3.5 mV/K typical - enables predictable voltage drift compensation in temperature-critical sensor biasing |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Voltage clamping on LIN bus transceiver supply rail during load-dump events. IC Role / Device Role / Timing Role: Zener diode acting as primary overvoltage protection element, shunting surge energy before it reaches the transceiver IC. Use Value: Prevents damage to LIN PHY during 12 V system transients up to 40 V/100 ms, enabled by 180 W peak power rating and AEC-Q101 qualification. |
Use Scenario: Precision biasing of bridge-based pressure sensor outputs in factory automation systems. IC Role / Device Role / Timing Role: Provides stable 4.3 V reference for op-amp input stage, minimizing offset drift across temperature. Use Value: Achieves <±0.5% reference stability from −40 °C to +85 °C due to low rdif and controlled −3.5 mV/K TC. |
| USB-C Port Protection Circuit | Smart Meter Power Supply Monitoring |
Use Scenario: Overvoltage clamp on VBUS line to protect USB PD controller during hot-plug surges. IC Role / Device Role / Timing Role: Fast-acting Zener clamp triggered within nanoseconds of overvoltage onset, limiting VBUS to safe levels. Use Value: Limits VBUS to ≤4.8 V during 100 µs surges, preventing latch-up in PD controllers rated for 5.5 V absolute max. |
Use Scenario: Undervoltage detection threshold in battery-backed real-time clock (RTC) circuitry. IC Role / Device Role / Timing Role: Zener diode used in comparator reference leg to trigger brown-out reset when main supply drops below 4.3 V. Use Value: Enables clean, repeatable 4.3 V trip point with <10 mV hysteresis due to tight VZ tolerance and low leakage (<3 µA). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B4V3,115 | Zener voltage 4.3 V (same tolerance), but higher differential resistance (≤900 Ω) and lower PZSM (100 W) | Limited to lower-energy transients; not AEC-Q101 qualified | Prefer TDZ4V3J,115 where automotive qualification or 180 W surge capability is required |
| MMSZ4V3ET1G | Same SOD-123 package, but wider VZ tolerance (±5%), higher leakage (≤5 µA at 1 V), and no AEC-Q101 certification | Suitable only for consumer-grade, non-safety-critical regulation | Select TDZ4V3J,115 when board space is constrained (SOD323F vs. SOD-123) and automotive compliance is mandatory |
Compared with BZX384-B4V3,115 and MMSZ4V3ET1G, TDZ4V3J,115 offers superior surge robustness (180 W vs. ≤100 W), tighter voltage tolerance (±2% vs. ±5%), and guaranteed automotive qualification - making it the only choice for AEC-compliant designs requiring minimal footprint and high transient immunity.

FAQ
What is the maximum continuous forward current for TDZ4V3J,115?
The maximum continuous forward current is 250 mA, as specified in Table 5 (Limiting Values). This rating applies at Tamb ≤ 25 °C with proper PCB copper area (16 mm² cathode pad); derating is required above 25 °C ambient per Rth(j-a) = 250 K/W.
Does TDZ4V3J,115 support reflow soldering only, or can it be hand-soldered?
Reflow soldering is the only recommended method per Section 11 of the datasheet. Hand-soldering is not advised due to thermal stress risks on the SOD323F package; peak reflow temperature must not exceed 260 °C for ≤10 seconds, consistent with J-STD-020 moisture sensitivity level 1.
How does the −3.5 mV/K temperature coefficient affect regulation accuracy over temperature?
At 4.3 V nominal, a −3.5 mV/K coefficient causes ~−0.35 V drift from −40 °C to +85 °C (125 K ΔT), resulting in ~−8% relative shift. For precision applications, this requires compensation in the reference circuit or selection of higher-VZ parts with positive TC to offset drift.
Is the 180 W non-repetitive peak power rating valid for all pulse durations?
No - the 180 W rating applies only to pulses ≤100 µs (square wave, Tj = 25 °C pre-surge). As shown in Figure 1, allowable PZSM decreases with longer pulses: e.g., 90 W at 300 µs, 45 W at 1 ms. Pulse duration must be verified against Fig 1 for design margin.
