Product details
Overview
HZM16NB3TL-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 16.35–17.09 V at 5 mA test current, 40 mW dynamic resistance, and 200 mW power dissipation in the MPAK (SC-59A) package.
For engineers reviewing the HZM16NB3TL-E datasheet, HZM16NB3TL-E pinout, HZM16NB3TL-E application, or HZM16NB3TL-E equivalent, this device serves as a stable, surface-mount voltage reference in power supply feedback loops, sensor biasing networks, and overvoltage protection clamps where tight tolerance and low temperature coefficient are required.
Technical Context
The HZM16NB3TL-E operates as a two-terminal shunt regulator, maintaining a stable reverse-biased breakdown voltage across its cathode–anode terminals under controlled test conditions (IZ = 5 mA, pulse width = 40 ms). Its zener voltage exhibits a positive temperature coefficient of +0.04 to +0.05 mV/°C near 16 V, minimizing drift in ambient-temperature-varying environments.
Designed for high-density SMT assembly, it uses a three-terminal MPAK package with Pin 1 (NC), Pin 2 (Anode), and Pin 3 (Cathode), enabling compact layout while isolating unused terminal functionality. Absolute maximum ratings include 150°C junction temperature and –55°C to +150°C storage range, supporting industrial-grade operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16.35–17.09 V at IZ = 5 mA - defines precise regulation point for feedback or reference use |
| Dynamic Resistance (rd) | 40 Ω max at IZ = 5 mA - ensures low output impedance and minimal voltage shift under load variation |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets thermal limit for continuous DC or pulsed operation in PCB-constrained designs |
| Reverse Current (IR) | 2 µA max at VR = 12.0 V - guarantees low leakage before breakdown, critical for standby power integrity |
| Temperature Coefficient (γZ) | +0.04 to +0.05 mV/°C - enables predictable, low-drift behavior in 0–70°C operating range |
| Junction Temperature (Tj) | 150°C max - supports reliable operation in thermally demanding industrial enclosures |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A, equivalent to SC-59A), 3-terminal surface-mount plastic package with 1.0 mm × 1.3 mm footprint, 0.55 mm nominal height, and 0.011 g mass.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16LT1G | Zener voltage 15.4–16.6 V (±5%), 300 mW Pd, SOT-23 package, 2-pin configuration | Lacks NC pin; requires different PCB pad layout and offers wider voltage tolerance | Choose for higher power handling and standard SOT-23 compatibility where pin count reduction is acceptable |
| MMSZ5245B-TP | Zener voltage 15.5–16.5 V (±5%), 500 mW Pd, SOD-123 package, 2-pin, 30 Ω rd | Higher power rating but looser tolerance and no NC terminal - less suitable for precision reference use | Prefer for cost-sensitive overvoltage protection where absolute voltage accuracy is secondary to surge robustness |
Compared with BZX84-C16LT1G and MMSZ5245B-TP, the HZM16NB3TL-E delivers tighter ±2.3% voltage tolerance and a dedicated NC pin for layout flexibility, making it preferable for precision analog references despite its lower 200 mW rating and MPAK-specific footprint.

FAQ
What is the exact zener voltage range for HZM16NB3TL-E at 5 mA test current?
The HZM16NB3TL-E has a guaranteed zener voltage range of 16.35 V to 17.09 V when tested at IZ = 5 mA, per Renesas datasheet R07DS0358EJ0600 Rev.6.00. This B3-grade specification reflects ±2.3% tolerance around the nominal 16.7 V center point, ensuring predictable regulation in precision analog circuits.
Does HZM16NB3TL-E require connection to Pin 1 (NC)?
No - Pin 1 of the HZM16NB3TL-E is designated No Connect (NC) and must remain electrically unconnected in the circuit. It is internally isolated and serves no functional purpose; routing or soldering to this terminal may compromise device reliability or violate Renesas' recommended layout practices.
What is the maximum allowable reverse current before breakdown for HZM16NB3TL-E?
The HZM16NB3TL-E specifies a maximum reverse current (IR) of 2 µA at VR = 12.0 V, measured at Ta = 25°C. This low leakage ensures minimal power loss and signal interference in standby or high-impedance bias networks prior to reaching the zener knee voltage.
Can HZM16NB3TL-E be used in place of a standard 16 V Zener diode like 1N4745A?
No - the HZM16NB3TL-E is not a drop-in replacement for through-hole devices such as the 1N4745A. It uses a 3-pin MPAK package with an NC terminal, differs in thermal derating (200 mW vs. 1 W), and is optimized for surface-mount precision rather than general-purpose regulation. Board redesign and validation are required.
What is the temperature coefficient behavior of HZM16NB3TL-E near its operating voltage?
The HZM16NB3TL-E exhibits a positive temperature coefficient of +0.04 to +0.05 mV/°C at approximately 16.7 V, as shown in Figure 2 of the datasheet. This results in predictable, low-magnitude voltage increase with rising ambient temperature - beneficial for applications requiring monotonic drift compensation without active circuitry.
