Product details
Overview
SZBZX84C13LT1G from onsemi is a 13 V ±5% Zener diode in SOT-23 package, rated for 250 mW power dissipation on FR-5 board, with 30 Ω dynamic impedance at 5 mA test current and 0.1 μA reverse leakage at 10.5 V. It provides precision voltage regulation in space-constrained portable electronics and high-density PCBs.
For engineers reviewing the SZBZX84C13LT1G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), thermal coefficient (+7.0 mV/°C), ESD rating (>16 kV HBM), and automotive-grade AEC-Q101 qualification.
Technical Context
This device operates as a two-terminal voltage reference diode with cathode-anode polarity, designed for stable reverse-biased breakdown regulation. Its 13 V nominal Zener voltage is specified at 5 mA test current (IZT), with guaranteed minimum/maximum values of 12.4 V and 14.1 V respectively.
The SOT-23 package features Pin 1 (Anode), Pin 2 (No Connection), and Pin 3 (Cathode), enabling unidirectional clamping and low-capacitance operation (120 pF at 0 V, 1 MHz). It meets AEC-Q101 for automotive use and supports Pb-free reflow soldering up to 260°C for 10 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13 V nominal, 12.4–14.1 V range at 5 mA - defines regulated output voltage under design load |
| Power Dissipation | 250 mW on FR-5 board - sets maximum continuous power handling without derating |
| Zener Impedance (ZZT) | 30 Ω max at 5 mA - determines regulation stiffness and output voltage variation under load changes |
| Reverse Leakage (IR) | 0.1 μA max at 10.5 V - ensures minimal quiescent current in standby or low-power modes |
| Temperature Coefficient | +7.0 mV/°C at 5 mA - quantifies voltage drift over operating temperature range (−65°C to +150°C) |
| Capacitance | 120 pF at 0 V, 1 MHz - impacts high-frequency noise filtering and signal integrity in RF-adjacent circuits |
| ESD Rating | Class 3 (>16 kV) per HBM - enables robust handling in manual assembly and end-user environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84C13LT1G | Standard industrial-grade variant; same 13 V rating, ±5% tolerance, but lacks AEC-Q101 qualification and automotive PPAP support | Not suitable for automotive production; acceptable for commercial portable devices and prototyping | Select when cost sensitivity outweighs automotive compliance requirements |
| SZBZX84C13LT3G | Identical electrical specs and AEC-Q101 qualification, but supplied in 10,000-piece tape-and-reel vs. 3,000-piece for SZBZX84C13LT1G | Same functional performance; optimized for high-volume automated placement | Select for large-scale manufacturing where reel size aligns with SMT line efficiency |
Compared with BZX84C13LT1G and SZBZX84C13LT3G, the SZBZX84C13LT1G uniquely balances automotive qualification with small-batch flexibility-its 3,000-unit reel supports both validation builds and Tier 2 supplier ramp, while retaining identical Zener characteristics and thermal behavior.

FAQ
What is the Zener voltage tolerance of SZBZX84C13LT1G?
The SZBZX84C13LT1G has a nominal Zener voltage of 13 V with a tolerance of ±5%, meaning the actual breakdown voltage falls between 12.4 V and 14.1 V when tested at 5 mA (IZT). This tolerance is confirmed in the Electrical Characteristics table on page 3 of the official onsemi datasheet, and applies across the full operating temperature range of −65°C to +150°C.
Is SZBZX84C13LT1G suitable for automotive applications?
Yes, SZBZX84C13LT1G is AEC-Q101 qualified and PPAP capable, making it suitable for automotive applications including body control modules, ADAS sensor interfaces, and infotainment power supplies. The "SZ" prefix explicitly denotes automotive-grade process control and site-specific qualification, distinguishing it from standard BZX84C13LT1G variants.
What is the thermal resistance of SZBZX84C13LT1G on FR-5 board?
The thermal resistance junction-to-ambient (RJA) for SZBZX84C13LT1G is 500°C/W when mounted on an FR-5 board, as specified in the Maximum Ratings table. This value corresponds to a 250 mW power dissipation limit at 25°C ambient, derating by 2.0 mW/°C above that temperature - critical for thermal margin analysis in enclosed automotive enclosures.
Does SZBZX84C13LT1G have a no-connect pin, and how should it be handled on PCB?
Yes, SZBZX84C13LT1G has Pin 2 designated as "No Connection" per the marking diagram and mechanical outline (Style 8). This terminal is internally unconnected and must remain electrically floating on the PCB - no copper trace, pad, or solder mask opening is required. Incorrect routing to ground or VCC would compromise device function and reliability.
What is the maximum reverse leakage current for SZBZX84C13LT1G?
The maximum reverse leakage current (IR) for SZBZX84C13LT1G is 0.1 μA at a reverse voltage (VR) of 10.5 V, as specified in the Electrical Characteristics table. This low leakage supports ultra-low-power operation in battery-backed systems and ensures minimal current draw in always-on monitoring circuits.
