Product details
Overview
HZU5BLL-JTLF-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage stabilization in low-power analog and digital supply rail regulation. It delivers a nominal Zener voltage of 5.1 V (B grade, min 5.14 V / max 5.37 V at IZ = 5 mA), with dynamic resistance of 130 Ω, reverse current ≤5 µA at VR = 1.5 V, and power dissipation up to 200 mW in an ultra-small URP surface-mount package.
For engineers reviewing the HZU5BLL-JTLF-E datasheet, HZU5BLL-JTLF-E pinout, HZU5BLL-JTLF-E application, or HZU5BLL-JTLF-E equivalent, key selection criteria include its tight 5.1 V Zener tolerance, low dynamic impedance for stable reference performance, thermal stability across –55°C to +150°C operating range, and compatibility with automated SMT assembly due to tape-and-reel packaging (3,000 pcs/reel).
Technical Context
This device operates as a two-terminal shunt regulator, maintaining a stable output voltage by conducting reverse current when the applied voltage exceeds its specified Zener breakdown threshold. Its silicon planar construction ensures consistent junction characteristics and predictable temperature coefficient behavior.
The HZU5BLL-JTLF-E is rated for 200 mW power dissipation at Ta = 25°C, with derating above 25°C per Fig.3 in the datasheet, and supports junction temperatures up to 150°C. It exhibits a negative temperature coefficient near 5.1 V - typical γZ ≈ –0.02 %/°C - confirmed in Fig.2 of the datasheet.
Key Specifications

FAQ
What is the exact Zener voltage range for HZU5BLL-JTLF-E at 5 mA test current?
The HZU5BLL-JTLF-E has a guaranteed Zener voltage range of 5.14 V to 5.37 V when tested at IZ = 5 mA and Ta = 25°C, corresponding to the "B" grade specification in the Renesas HZU Series datasheet R07DS0423EJ1000. This 2.5% tolerance band ensures predictable regulation behavior in precision 5 V reference designs.
Is HZU5BLL-JTLF-E compatible with lead-free reflow soldering processes?
Yes, HZU5BLL-JTLF-E is qualified for lead-free reflow soldering per J-STD-020. Its URP package withstands peak temperatures up to 260°C for 10 seconds, matching standard Pb-free profile requirements. The device is RoHS-compliant and marked accordingly on the tape reel label per Renesas documentation.
Does HZU5BLL-JTLF-E have a specified temperature coefficient, and what is its typical value?
Yes - the HZU5BLL-JTLF-E exhibits a negative temperature coefficient near 5.1 V, with typical γZ ≈ –0.02 %/°C as shown in Fig.2 of the datasheet. This means its Zener voltage decreases by approximately 1.02 mV/°C over the operating range, a characteristic critical for temperature-compensated reference designs.
What is the maximum reverse leakage current for HZU5BLL-JTLF-E at 1.5 V applied voltage?
The maximum reverse leakage current (IR) for HZU5BLL-JTLF-E is 5 µA when VR = 1.5 V and Ta = 25°C, as specified in the Electrical Characteristics table on page 2 of the datasheet. This low leakage supports ultra-low-power applications such as battery-backed real-time clocks and sensor wake-up circuits.
Can HZU5BLL-JTLF-E be used as a substitute for the older HZU5.1B part?
Yes - HZU5BLL-JTLF-E is the current production marking variant of the HZU5.1B Zener diode, sharing identical electrical specifications, URP package, pinout, and thermal ratings. The "JTLF-E" suffix denotes tape-and-reel packaging per Renesas' ordering convention and does not indicate functional or parametric deviation from HZU5.1B.
