Product details
Overview
HZM16NB2TR-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 16.35–17.09 V at 5 mA, with dynamic resistance of 40 Ω, power dissipation up to 200 mW, and operates within –55°C to +150°C storage temperature range. It is commonly used in voltage reference generation for sensor signal conditioning and power supply feedback loops.
For engineers reviewing the HZM16NB2TR-E datasheet, HZM16NB2TR-E pinout, HZM16NB2TR-E application, or HZM16NB2TR-E equivalent, key selection criteria include zener voltage tolerance (±2.3% at 16.72 V nominal), low dynamic impedance, MPAK surface-mount package compatibility, thermal stability across industrial temperature ranges, and compliance with JEITA package code PLSP0003ZC-A.
Technical Context
This Zener diode employs a silicon epitaxial planar structure optimized for stable reverse-breakdown behavior under DC and pulsed conditions (Pw = 40 ms). Its junction temperature rating of 150°C supports operation in thermally constrained PCB layouts without derating below 25°C ambient.
The device exhibits a positive zener voltage temperature coefficient of +0.04 mV/°C near 16 V (per Fig.2), enabling predictable drift compensation in reference designs. It is rated for 2 μA maximum reverse leakage at VR = 12 V and requires no external biasing circuitry-functioning as a two-terminal shunt regulator.
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 minimal output voltage variation under load current changes |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous DC power handling before thermal shutdown risk |
| Reverse Current (IR) | 2 μA max at VR = 12 V - guarantees low quiescent current in standby or high-impedance sensing nodes |
| Junction Temperature (Tj) | 150°C maximum - enables reliable operation in enclosed industrial enclosures without forced cooling |
| Package | MPAK (JEITA PLSP0003ZC-A) - 3-pin SMT package with 1.0 mm × 1.3 mm footprint for high-density layout |
| Zener Grade | B2 - tighter tolerance band vs. B/B1/B3 grades, supporting higher-accuracy reference applications |
Pinout & Package
MPAK package (JEITA code PLSP0003ZC-A) is a compact 3-pin surface-mount plastic package measuring 1.0 mm × 1.3 mm × 0.55 mm (L × W × H), optimized for automated placement and reflow soldering on dense PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Electrically isolated terminal - must remain unconnected; no internal bond wire or junction |
| 2 | Anode | Forward-biased terminal during conduction; connected to lower-potential side in shunt regulator configuration |
| 3 | Cathode | Zener breakdown terminal - connected to regulated output node and current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B2 zener voltage tolerance | ±2.3% at 16.72 V nominal - enables tighter regulation than standard-grade Zeners in feedback paths |
| Low dynamic impedance | 40 Ω max - minimizes output ripple and improves line/load regulation in precision references |
| MPAK surface-mount package | 0.55 mm height, 1.0 mm × 1.3 mm footprint - supports miniaturized designs and high-volume pick-and-place assembly |
| High junction temperature rating | 150°C - allows uninterrupted operation in sealed enclosures or near heat-generating components |
| Pulse-tested characterization | Verified at Pw = 40 ms - ensures stable breakdown behavior under transient overvoltage conditions |

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 |
|---|---|---|---|
| MMSZ4687T1G (ON Semiconductor) | Zener voltage 16 V ±5%, rd = 40 Ω, SOD-123 package (2.7 mm × 1.6 mm) | Larger footprint and looser tolerance - suitable for non-critical clamping but not precision references | Select when board space permits larger package and ±5% regulation is acceptable |
| BZX84-C16 (Nexperia) | Zener voltage 16 V ±5%, rd = 50 Ω, SOT-23 package (3.0 mm × 1.4 mm) | Higher dynamic resistance and wider tolerance - less effective in low-noise reference paths | Prefer for cost-sensitive consumer applications where size and accuracy are secondary |
Compared with MMSZ4687T1G and BZX84-C16, HZM16NB2TR-E offers tighter B2-grade voltage tolerance (±2.3%), identical dynamic resistance, and a significantly smaller MPAK footprint-making it optimal for space-constrained, high-accuracy industrial reference designs where thermal stability and low drift are prioritized.

FAQ
What is the exact zener voltage range for HZM16NB2TR-E at 5 mA test current?
The HZM16NB2TR-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 corresponds to the B2 grade specification per Renesas datasheet R07DS0358EJ0600, and reflects a ±2.3% tolerance centered at 16.72 V. The device maintains this range across its qualified operating temperature span without recalibration.
Is pin 1 of HZM16NB2TR-E electrically connected internally?
No - pin 1 of HZM16NB2TR-E is designated NC (No Connect) and contains no internal bond wire or semiconductor junction. It must remain unconnected on the PCB to avoid unintended coupling or mechanical stress. The functional terminals are pin 2 (anode) and pin 3 (cathode), as confirmed in the "Pin Arrangement" diagram on page 1 of the official datasheet.
What is the maximum allowable power dissipation for HZM16NB2TR-E at 85°C ambient temperature?
Per Figure 3 in the HZM16NB2TR-E datasheet, the maximum allowable power dissipation at Ta = 85°C is approximately 140 mW. This is derived from the linear derating curve starting at 200 mW at 25°C and decreasing at ~2.2 mW/°C beyond 25°C. Exceeding this limit risks junction temperature exceeding 150°C, potentially causing irreversible degradation.
Does HZM16NB2TR-E meet RoHS and lead-free requirements?
Yes - HZM16NB2TR-E complies with EU RoHS Directive 2011/65/EU and is manufactured as a lead-free device. Renesas confirms halogen-free and green material content in the MPAK package per their environmental compliance documentation, and the part carries the "EU RoHS Compliant" marking on official distribution records.
Can HZM16NB2TR-E be used as a direct replacement for HZM16NB1TR-E in an existing design?
Yes - HZM16NB2TR-E and HZM16NB1TR-E share identical package, pinout, absolute maximum ratings, and thermal characteristics; only the zener voltage tolerance differs (B2: 16.35–17.09 V vs. B1: 16.94–17.70 V). Substituting HZM16NB2TR-E provides tighter regulation without layout or schematic changes, provided the design accommodates the lower nominal VZ of 16.72 V instead of 17.32 V.
