Product details
Overview
HZS16-1TD-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power stabilized power supplies, with a nominal zener voltage of 16.3–17.1 V at 5 mA test current, 400 mW maximum power dissipation, and 12.0 Ω typical dynamic resistance. It operates within −55°C to +175°C storage temperature range and is qualified for industrial-grade applications including office equipment and test instrumentation.
For engineers reviewing the HZS16-1TD-E datasheet, HZS16-1TD-E pinout, HZS16-1TD-E application, or HZS16-1TD-E equivalent, this device serves as a compact, high-stability voltage reference in linear regulator feedback paths, overvoltage clamping circuits, and analog signal conditioning where tight zener tolerance and low dynamic impedance are required.
Technical Context
The HZS16-1TD-E employs a silicon planar junction structure optimized for stable reverse breakdown behavior under DC bias conditions. Its zener voltage exhibits a positive temperature coefficient near +0.05 %/°C (≈+8.0 mV/°C) in the 16–17 V range, enabling predictable thermal drift compensation in reference designs.
Rated for 400 mW power dissipation at 25°C ambient, its derating curve shows linear reduction to zero at 150°C, supporting reliable operation in thermally constrained PCB layouts. The device is specified with ≤1 µA reverse leakage at VR = 12.0 V and meets JEITA package standard GRZZ0002ZC-A (MHD).

FAQ
What is the exact zener voltage range specified for HZS16-1TD-E?
The HZS16-1TD-E has a guaranteed zener voltage range of 16.3 V to 17.1 V when tested at IZ = 5 mA and Ta = 25°C, corresponding to Grade "-3" in the HZS16 family per Renesas datasheet REJ03G0184-0500 Rev.5.00. This ±2.5% tolerance supports precision regulation where tighter control than standard 5% Zeners is required. The HZS16-1TD-E maintains this specification across its qualified operating temperature range.
Does HZS16-1TD-E have a defined temperature coefficient, and how does it affect circuit performance?
Yes, the HZS16-1TD-E exhibits a positive zener voltage temperature coefficient of approximately +0.05 %/°C (or +8.0 mV/°C) in the 16–17 V range, as shown in Figure 2 of the datasheet. This means its breakdown voltage increases by ~0.8 V over a 100°C ambient rise. Designers should account for this drift in high-precision references; however, the coefficient is stable and repeatable, enabling predictable compensation in temperature-critical applications. The HZS16-1TD-E data sheet confirms this behavior applies to all HZS16 variants.
What is the maximum reverse leakage current for HZS16-1TD-E, and under what condition is it measured?
The maximum reverse leakage current for HZS16-1TD-E is 1 µA, measured at VR = 12.0 V and Ta = 25°C. This low leakage ensures minimal error contribution in high-impedance reference networks and preserves efficiency in battery-powered or low-quiescent-current designs. The value is confirmed in the Electrical Characteristics table on page 4 of the official Renesas datasheet REJ03G0184-0500, and applies specifically to the HZS16-1TD-E variant.
Can HZS16-1TD-E be used in surface-mount designs, or is it strictly through-hole?
HZS16-1TD-E uses the MHD package - an axial-leaded, through-hole format with 5 mm lead pitch and phenolic paper substrate, explicitly intended for high-speed automatic insertion and wave soldering. It is not a surface-mount device and lacks solder pads or gull-wing leads. For SMT alternatives, Renesas offers other families (e.g., UDZ series), but the HZS16-1TD-E itself requires through-hole mounting per its JEITA GRZZ0002ZC-A mechanical specification.
Is HZS16-1TD-E rated for automotive or safety-critical applications?
No, the HZS16-1TD-E is classified as a "Standard" quality grade device per Renesas documentation, intended for computers, office equipment, communications gear, and industrial test instruments - not for automotive, medical life-support, or aerospace systems. Its datasheet explicitly excludes use in "Specific" applications (e.g., aircraft, nuclear controls, surgical implants) without written consent. The HZS16-1TD-E meets industrial reliability standards but carries no AEC-Q200 qualification or extended-temperature automotive certification.
