Product details
Overview
HZM5.1NB3TL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits, with a nominal zener voltage of 5.14–5.37 V at 5 mA, dynamic resistance of ≤130 Ω, power dissipation rating of 200 mW, and MPAK surface-mount package optimized for high-density PCB layouts.
For engineers reviewing the HZM5.1NB3TL-E datasheet, HZM5.1NB3TL-E pinout, HZM5.1NB3TL-E application, or HZM5.1NB3TL-E equivalent, key selection criteria include its B3-grade zener voltage tolerance (±2.3% typical), low temperature coefficient (≈+0.025 mV/°C near 5.1 V), NC terminal isolation, and suitability for voltage reference, overvoltage protection, and biasing in industrial sensor interfaces and portable power management systems.
Technical Context
The HZM5.1NB3TL-E operates as a two-terminal shunt regulator, where reverse-biased conduction across the PN junction maintains stable voltage under varying load current. Its epitaxial planar structure ensures tight VZ distribution and low leakage.
It features a non-connected (NC) terminal to enable standardized MPAK footprint compatibility across the HZM-N series while isolating unused internal nodes - critical for layout consistency and automated assembly. Thermal derating follows a linear 200 mW maximum at TA = 25°C, decreasing to zero at 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.14–5.37 V at IZ = 5 mA - defines stable regulation point for 5 V reference designs |
| Dynamic Resistance (rd) | ≤130 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW at TA = 25°C - sets maximum continuous power handling before thermal shutdown |
| Reverse Current (IR) | ≤5 µA at VR = 1.5 V - ensures minimal leakage in standby or low-current bias networks |
| Junction Temperature (Tj) | –55 to +150°C - supports operation in extended industrial environments without external heatsinking |
| Temperature Coefficient (γZ) | ≈+0.025 mV/°C near 5.1 V - enables predictable drift compensation in precision references |

FAQ
What is the exact zener voltage range specified for HZM5.1NB3TL-E at 5 mA test current?
The HZM5.1NB3TL-E has a guaranteed zener voltage range of 5.14 V to 5.37 V when tested at IZ = 5 mA, corresponding to its B3 grade per the Renesas R07DS0358EJ0600 datasheet. This ±2.3% tolerance enables high-accuracy voltage referencing without post-production trimming in the HZM5.1NB3TL-E design.
Does HZM5.1NB3TL-E have a functional third pin, and what is its purpose?
No - Pin 1 of the HZM5.1NB3TL-E is explicitly designated NC (No Connection) in the official datasheet pin arrangement. It is internally unconnected and serves solely to maintain mechanical and layout compatibility across the entire HZM-N series, allowing standardized PCB footprints regardless of zener voltage variant.
What is the maximum allowable power dissipation for HZM5.1NB3TL-E at 70°C ambient temperature?
Per Figure 3 in the HZM5.1NB3TL-E datasheet, power dissipation derates linearly from 200 mW at 25°C to 0 mW at 150°C. At 70°C ambient, the maximum allowable Pd is approximately 133 mW - calculated using the slope of –2.22 mW/°C derived from the 200 mW / 90°C thermal span.
How does the temperature coefficient of HZM5.1NB3TL-E compare to other 5.1 V Zener diodes?
The HZM5.1NB3TL-E exhibits a temperature coefficient of approximately +0.025 mV/°C near its 5.1 V operating point, as shown in Figure 2 of the datasheet. This is significantly more stable than generic 5.1 V Zeners (often ±2–5 mV/°C), making the HZM5.1NB3TL-E especially suitable for precision references where drift must remain below 0.5 mV over 20°C ambient shifts.
Is HZM5.1NB3TL-E RoHS-compliant and halogen-free?
Yes - the HZM5.1NB3TL-E complies with EU RoHS Directive 2011/65/EU and is halogen-free, as confirmed by Renesas' environmental compliance documentation referenced in the datasheet colophon and supported by material declarations for the MPAK package (PLSP0003ZC-A).
