Product details
Overview
HZM16NB3TR-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits. It delivers a nominal zener voltage of 16.35 V to 17.09 V at 5 mA test current, with dynamic resistance of 40 Ω max, power dissipation of 200 mW, and operates within –55°C to +150°C storage temperature range. It is used in voltage reference supplies for sensor signal conditioning and ADC biasing.
For engineers reviewing the HZM16NB3TR-E datasheet, HZM16NB3TR-E pinout, HZM16NB3TR-E application, or HZM16NB3TR-E equivalent, key selection considerations include its B3-grade zener voltage tolerance (±2.3% typical), MPAK surface-mount package compatibility with high-density PCB layouts, thermal stability up to 150°C junction temperature, and suitability for low-current (<5 mA) stabilization tasks where tight regulation and minimal temperature drift are required.
Technical Context
The HZM16NB3TR-E employs a silicon epitaxial planar structure optimized for stable reverse-breakdown behavior under DC and pulsed conditions (40 ms pulse width). Its zener voltage exhibits a positive temperature coefficient of approximately +0.04 mV/°C near 16 V, enabling predictable drift compensation in reference designs.
It functions exclusively in reverse-biased mode with defined anode (Pin 2) and cathode (Pin 3) terminals; Pin 1 is NC. The device is rated for 2 mA minimum reverse current to maintain regulation and supports operation up to 150°C junction temperature without derating beyond ambient-dependent power limits per Fig. 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16.35 V to 17.09 V at IZ = 5 mA - defines stable regulation window for reference design margin |
| Dynamic Resistance (rd) | ≤40 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous DC power before thermal derating applies |
| Reverse Current (IR) | ≤2 μA at VR = 12.0 V - ensures low leakage in standby or high-impedance bias networks |
| Junction Temperature (Tj) | 150°C maximum - enables use in thermally constrained industrial or automotive under-hood environments |
| Temperature Coefficient (γZ) | +0.04 mV/°C - quantifies voltage drift per degree, critical for temperature-compensated references |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A), surface-mount, 3-terminal plastic package with 1.0 mm × 1.3 mm footprint and 0.55 mm terminal pitch. Mass: 0.011 g (typ).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must remain floating - no routing or soldering required |
| 2 | Anode | Connected to lower-potential node in reverse-bias configuration; defines current entry path during regulation |
| 3 | Cathode | Connected to higher-potential node; output reference voltage appears at this terminal relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| B3-grade voltage tolerance | ±2.3% zener voltage spread (16.35–17.09 V) - enables tighter system-level reference accuracy without trimming |
| Low dynamic resistance | 40 Ω max at 5 mA - minimizes output voltage variation under changing load current |
| MPAK surface-mount package | 0.011 g mass, 1.0 mm × 1.3 mm footprint - supports automated placement and high board density in space-constrained modules |
| High junction temperature rating | 150°C max - allows operation in sealed enclosures or near heat-generating components without external heatsinking |
| Pulse-tested characterization | Specified with 40 ms pulse width - ensures parameter validity under transient regulation conditions common in power-up sequencing |

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%), 350 mW Pd, SOT-23 package, rd ≤40 Ω | Higher power rating but wider voltage tolerance; requires layout change due to different footprint | Select when higher surge power handling is needed and ±5% VZ tolerance is acceptable. |
| MMSZ5245B-TP | Zener voltage 15.3–16.7 V (±5%), 500 mW Pd, SOD-123 package, rd ≤35 Ω | Higher power and lower rd, but larger package (2.7 mm × 1.6 mm) and non-NC pin configuration | Choose for cost-sensitive designs needing higher reliability margin and where board space permits larger footprint. |
Compared with BZX84-C16LT1G and MMSZ5245B-TP, the HZM16NB3TR-E offers tighter B3-grade voltage tolerance (±2.3%) and a compact MPAK footprint ideal for ultra-dense layouts, though at lower absolute power rating - making it optimal for precision, space-constrained, low-current reference roles rather than general-purpose shunt regulation.

FAQ
What is the exact zener voltage range specified for HZM16NB3TR-E?
The HZM16NB3TR-E has a guaranteed zener voltage range of 16.35 V to 17.09 V when tested at IZ = 5 mA and Ta = 25°C. This B3-grade specification reflects ±2.3% tolerance around the nominal 16.7 V point, confirmed in the R07DS0358EJ0600 datasheet Table on page 3. The HZM16NB3TR-E maintains this range across its qualified operating temperature span without recalibration.
Does HZM16NB3TR-E have a built-in capacitor or ESD protection?
No, the HZM16NB3TR-E is a basic silicon epitaxial planar Zener diode with no integrated capacitor or ESD protection structure. Its construction consists solely of the PN junction optimized for stable reverse breakdown. External TVS or RC filtering must be added if transient suppression or ESD immunity is required in the target application using HZM16NB3TR-E.
Can HZM16NB3TR-E be used in series or parallel configurations?
The HZM16NB3TR-E is not characterized or recommended for parallel operation due to mismatched dynamic resistance and thermal runaway risk. Series connection is electrically permissible but requires individual current limiting; however, voltage additivity is not guaranteed due to process variation. For multi-voltage references, discrete HZM16NB3TR-E units should be used independently per channel rather than cascaded.
What is the meaning of "TR" in the part number HZM16NB3TR-E?
The "TR" suffix in HZM16NB3TR-E indicates tape-and-reel packaging with 3,000 pieces per reel, per Renesas' ordering convention defined in the datasheet's "Ordering Information" section. The "-E" denotes compliance with JEDEC standard lead-free and RoHS requirements. This packaging format ensures compatibility with automated SMT assembly lines for the HZM16NB3TR-E.
Is Pin 1 of HZM16NB3TR-E internally connected or usable as a heatsink pad?
Pin 1 of the HZM16NB3TR-E is explicitly designated as "NC" (No Connect) in the datasheet's Pin Arrangement diagram and must remain unconnected in the PCB layout. It is not internally bonded and provides no electrical or thermal function. Routing or soldering to Pin 1 may compromise mechanical integrity or cause unintended shorts; the HZM16NB3TR-E relies on thermal conduction through Pins 2 and 3 only.
