Product details
Overview
TDZ27J,115 from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation and reference functions in space-constrained PCBs. It delivers a nominal Zener voltage of 27 V at 2 mA, with differential resistance ≤250 Ω, total power dissipation up to 500 mW at 25 °C ambient, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TDZ27J,115 datasheet, TDZ27J,115 pinout, TDZ27J,115 application, or TDZ27J,115 equivalent, key selection criteria include Zener voltage tolerance (±0.5 V), low reverse leakage (<0.05 µA at VR = 22 V), thermal resistance (25 K/W junction-to-solder-point), and non-repetitive peak reverse current capability (1 A).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its 27 V nominal Zener voltage is specified at IZ = 2 mA, with temperature coefficient of +21.4 mV/K and typical reverse current <0.05 µA at 22 V.
The device uses a planar epitaxial silicon structure optimized for low noise and tight voltage tolerance. Thermal performance is defined with FR4 PCB mounting (16 mm² cathode pad), enabling reliable operation up to 150 °C junction temperature and supporting automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 26.5 V to 27.5 V at IZ = 2 mA - ensures ±0.5 V regulation window for stable reference design |
| Differential Resistance (rdif) | ≤250 Ω at IZ = 2 mA - minimizes output voltage shift under load variation |
| Reverse Current (IR) | <0.05 µA at VR = 22 V - enables ultra-low standby power in battery-backed circuits |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 25 °C - supports continuous regulation in compact SMT layouts without forced cooling |
| Thermal Resistance (Rth(j-sp)) | 25 K/W junction-to-solder-point - allows direct thermal coupling to PCB copper for effective heat extraction |
| Non-repetitive Peak Reverse Current (IZSM) | 1 A at tp = 100 µs - provides transient overvoltage clamping capability in surge-prone interfaces |
| AEC-Q101 Qualified | Validated for automotive discrete semiconductor stress testing - meets requirements for engine control, body electronics, and ADAS subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B27,115 | Same 27 V nominal Zener voltage, but SOD323 package (not SOD323F); higher rdif (300 Ω vs. 250 Ω); no AEC-Q101 qualification | Targeted at industrial/commercial rather than automotive use; less robust thermal pad layout | Select when automotive qualification is unnecessary and legacy SOD323 footprint compatibility is required |
| MMSZ5260B-TP | 27 V Zener, SOD-123 package; higher Ptot (500 mW same), but rdif = 350 Ω and IR = 0.1 µA at 22 V | Higher leakage and larger footprint reduce suitability for low-power, high-density designs | Choose only if SOD-123 is mandated by existing board layout and tighter leakage is not critical |
Compared with BZX384-B27,115 and MMSZ5260B-TP, TDZ27J,115 offers superior thermal coupling (25 K/W vs. ≥30 K/W), lower leakage (0.05 µA vs. ≥0.1 µA), and automotive qualification-making it the preferred choice for safety-critical, thermally constrained, or long-life embedded systems.

FAQ
What is the maximum continuous reverse power dissipation for TDZ27J,115 at 85 °C ambient?
At 85 °C ambient, derated power dissipation is calculated using Rth(j-a) = 250 K/W: Ptot = (Tj(max) − Tamb) / Rth(j-a) = (150 − 85) / 250 = 260 mW. This value ensures safe continuous operation without exceeding 150 °C junction temperature.
How does the 27 V Zener voltage tolerance affect feedback accuracy in a 12 V DC-DC converter?
With ±0.5 V tolerance at 27 V, the reference uncertainty is ±1.85%. When used in a resistive divider to monitor 12 V output (e.g., 27 V reference → 12 V via 2:1 ratio), this translates to ±0.22 V absolute output voltage error-within typical 12 V supply spec of ±5%.
Can TDZ27J,115 be used as a standalone overvoltage protector for a 24 V CAN bus interface?
No. TDZ27J,115 is a Zener diode-not a transient voltage suppressor. While it clamps near 27 V, its 1 A non-repetitive surge rating and 500 mW steady-state limit make it unsuitable for repeated CAN bus ESD events. A dedicated TVS like PESD5V0S1BA is required for compliant CAN protection.
Is the SOD323F package compatible with standard reflow profiles for lead-free soldering?
Yes. Nexperia specifies reflow soldering only, with peak temperature ≤260 °C and time above 217 °C limited to 60 seconds. The SOD323F outline matches IPC-7351B SOIC-2 footprint rules, and the 0.65 mm lead pitch supports standard stencil aperture design for 100% solder joint yield.
