Product details
Overview
TDZ8V2J,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 8.2 V at 5 mA, with differential resistance of 80 Ω, temperature coefficient of +3.2 mV/K, and total power dissipation up to 500 mW at 25 °C ambient - used in automotive ECU voltage reference and sensor biasing networks.
For engineers reviewing the TDZ8V2J,115 datasheet, TDZ8V2J,115 pinout, TDZ8V2J,115 application, or TDZ8V2J,115 equivalent, key selection criteria include Zener voltage tolerance (±2.5% at 8.2 V), low thermal resistance (25 K/W junction-to-solder-point), AEC-Q101 qualification, and SC-90 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its positive temperature coefficient (+3.2 mV/K) enables predictable drift compensation in multi-diode reference strings, and its 80 Ω differential resistance ensures minimal output impedance over 1–10 mA operating range.
The device is qualified per AEC-Q101 for automotive use, with junction temperature rated to 150 °C and storage temperature spanning −65 °C to +150 °C. Thermal performance relies on FR4 PCB mounting with 16 mm² cathode pad, achieving Rth(j-a) = 250 K/W in free air and Rth(j-sp) = 25 K/W to solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.04 V to 8.36 V at IZ = 5 mA - defines tight 2.5% tolerance band for stable reference generation |
| Differential Resistance (rdif) | 80 Ω max at IZ = 5 mA - ensures low dynamic impedance for minimal regulation error under load variation |
| Temperature Coefficient (SZ) | +3.2 mV/K at IZ = 5 mA - enables predictable, linear voltage drift for temperature-compensated designs |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 25 °C - supports continuous operation in compact, unheatsinked automotive modules |
| Reverse Current (IR) | 0.70 µA max at VR = 6.56 V - guarantees low leakage in battery-backed or ultra-low-power standby circuits |
| Non-repetitive Peak Reverse Power | 40 W at tp = 100 µs - provides surge immunity against ESD and load-dump transients in 12 V systems |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - allows safe forward conduction during polarity-reversal protection scenarios |
Pinout & Package
SOD323F (SC-90) is a 2-pin surface-mount plastic package measuring 2.7 × 1.6 × 0.95 mm, with gull-wing leads and cathode marked by a bar on the top surface. Mounting requires reflow only, using the recommended 0.6 mm wide solder land per terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; marking bar identifies this terminal; carries reverse current during Zener operation |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path; serves as reference return in shunt regulator topology |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114 |
| Low differential resistance | 80 Ω max ensures <1% output deviation across 1–10 mA load current swing in reference supply rails |
| Small-outline SMD package | SOD323F footprint occupies <1.5 mm² board area - enables placement near noise-sensitive analog ICs without routing parasitics |
| Controlled temperature coefficient | +3.2 mV/K allows predictable tracking with silicon sensors or complementary NTC networks in closed-loop biasing |
| High surge robustness | Withstands 40 W non-repetitive reverse pulses - protects downstream LDOs and microcontrollers from ISO 7637-2 pulse 1/2a transients |
Applications
| Automotive Sensor Biasing | Microcontroller Reset Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B8V2,115 | Same Zener voltage (8.2 V), but higher differential resistance (120 Ω) and no AEC-Q101 qualification | Limited to commercial-grade consumer electronics; not approved for automotive underhood use | Select when cost sensitivity outweighs automotive qualification and tighter regulation stability |
| MMSZ4689T1G | 8.2 V nominal, but wider tolerance (±5%), higher leakage (1 µA), and SOD-123 package (larger footprint) | Requires larger PCB area; less suitable for space-constrained automotive modules | Choose if existing SOD-123 layout reuse is prioritized over thermal performance and AEC compliance |
Compared with TDZ8V2J,115, BZX384-B8V2,115 trades automotive reliability for lower cost, while MMSZ4689T1G sacrifices precision and board area efficiency for broader distributor availability - TDZ8V2J,115 uniquely balances AEC-Q101 validation, SC-90 miniaturization, and 2.5% VZ tolerance in one package.

FAQ
What is the maximum continuous reverse current for TDZ8V2J,115 at 25 °C ambient?
The device supports a maximum continuous reverse current of 61 mA, calculated from Ptot = 500 mW and VZ = 8.2 V (500 mW ÷ 8.2 V ≈ 61 mA). This value assumes no additional thermal derating and full 16 mm² copper pad implementation per datasheet mounting condition [2].
Does TDZ8V2J,115 require heatsinking in standard PCB layouts?
No heatsink is required: with Rth(j-a) = 250 K/W and Ptot = 500 mW, junction temperature rise is ~125 K above ambient - acceptable within the 150 °C Tj limit when mounted on FR4 with specified 16 mm² cathode pad. Derating begins above 25 °C ambient per Figure 1 in the datasheet.
Can TDZ8V2J,115 be used in series for higher-voltage references?
Yes - its +3.2 mV/K temperature coefficient and tight 2.5% VZ tolerance enable predictable series stacking. Two devices yield ~16.4 V with matched drift; parallel connection is not recommended due to mismatched knee characteristics and current-sharing instability.
Is the SOD323F package compatible with standard reflow profiles for lead-free assembly?
Yes - Nexperia specifies reflow soldering only, with peak temperature up to 260 °C for ≤10 seconds, matching IPC/JEDEC J-STD-020D. The package withstands thermal shock from −65 °C to +150 °C per AEC-Q101 stress testing, confirming robustness in automotive reflow cycles.
