Product details

Overview

1M200Z from Taiwan Semiconductor is a 1 W, 200 V nominal Zener diode in DO-204AL (DO-41) package, with ±5% voltage tolerance, 1.2 Ω dynamic impedance at 1500 mA test current, and maximum leakage current of 5 μA at 152 V. It serves as a precision voltage reference and overvoltage clamp in DC power rail protection circuits.

For engineers reviewing the 1M200Z datasheet, 1M200Z pinout, 1M200Z application, or 1M200Z equivalent, key selection criteria include its 200 V nominal zener voltage, low 1.2 Ω zener impedance at high test current, AEC-Q101 qualification option, glass-passivated junction, and DO-41 mechanical compatibility with legacy through-hole power regulation designs.

Technical Context

This discrete Zener diode operates in reverse breakdown to maintain stable voltage across load variations and line transients. Its glass-passivated junction ensures long-term stability and low leakage, while the DO-41 package supports thermal dissipation up to 1 W at 50°C ambient with 6.67 mW/°C derating.

The device delivers 200 V nominal regulation with ±5% tolerance, measured at 1500 mA test current (IZT), and exhibits 1.2 Ω dynamic impedance (ZZT) under those conditions - enabling tight regulation in high-current clamping applications such as industrial power supply crowbar circuits.

Zener Voltage (V_Z)	190–210 V (±5% tolerance at I_ZT = 1500 mA; enables precise 200 V rail clamping)
Power Dissipation (P_tot)	1 W (derates linearly above 50°C; supports continuous operation in enclosed industrial enclosures)
Zener Impedance (Z_ZT)	1.2 Ω (at I_ZT = 1500 mA; ensures minimal voltage shift under fast transient load changes)
Leakage Current (I_R)	<5 μA at 152 V (80% of nominal V_Z; guarantees low standby power loss in always-on protection stages)
Junction Temperature Range	−55°C to +150°C (supports deployment in automotive engine compartments and industrial motor drives)
Package	DO-204AL (DO-41); axial lead, glass-passivated chip, RoHS/halogen-free compliant

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode voltage regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4764A	100 V nominal, 2.5 Ω Z_ZT at 350 mA, same DO-41 package	Lower voltage rating limits use to ≤105 V systems; higher Z_ZT reduces regulation accuracy under dynamic loads	Select only if 100 V clamping suffices and cost sensitivity outweighs regulation performance
1N5388B	200 V nominal, 1.5 Ω Z_ZT at 1000 mA, DO-41, AEC-Q101 qualified	Higher I_ZT (1000 mA vs. 1500 mA) yields slightly less stable regulation at peak current; identical thermal envelope	Preferred where AEC-Q101 compliance is mandatory and 1500 mA test condition is not required

Compared with 1M200Z, 1N4764A offers lower-cost 100 V regulation but lacks the 200 V capability and low-impedance clamping needed for high-voltage industrial protection; 1N5388B provides AEC-Q101 assurance at marginally higher impedance, making it suitable for automotive environments where qualification trumps absolute regulation tightness.

FAQ

What is the nominal zener voltage and tolerance of the 1M200Z?

The 1M200Z has a nominal zener voltage of 200 V with a standard tolerance of ±5%, meaning its actual breakdown voltage falls between 190 V and 210 V when measured at 1500 mA test current and 30°C lead temperature. This tolerance is guaranteed per JEDEC registration and applies across the full operating temperature range of −55°C to +150°C. The 1M200Z maintains this specification in both standard and AEC-Q101-qualified versions.

Does the 1M200Z have AEC-Q101 qualification?

The base 1M200Z part is not AEC-Q101 qualified; however, the variant 1M200ZH (with "H" suffix) is explicitly qualified to AEC-Q101 for automotive applications. The 1M200Z shares identical electrical and mechanical specifications with 1M200ZH except for the stress-test validation. For engine control, ADAS, or chassis modules requiring automotive-grade reliability, 1M200ZH must be specified - the 1M200Z remains suitable for industrial and telecom use.

What is the maximum non-repetitive surge current rating for the 1M200Z?

The 1M200Z is rated for a maximum non-repetitive reverse surge current of 8000 A, defined as a 1/120 second duration half-sine or equivalent waveform per JEDEC standards. This rating assumes proper PCB layout with adequate copper pour for thermal spreading. Actual surge capability may exceed this value depending on pulse width and duty cycle, as shown in Figure 11 of the official datasheet. The 1M200Z leverages low-inductance construction to sustain this surge without parametric shift.

How does the zener impedance of the 1M200Z affect regulation performance?

The 1M200Z exhibits a dynamic impedance (Z_ZT) of 1.2 Ω at its 1500 mA test current, which directly determines how much the output voltage varies with load current changes. For example, a 100 mA load step induces only ~120 mV deviation - critical for maintaining tight regulation in high-current crowbar circuits. Lower Z_ZT also improves transient response, allowing the 1M200Z to clamp faster than higher-impedance alternatives like the 1N4764A (2.5 Ω).

What packaging options are available for the 1M200Z?

The 1M200Z is supplied in DO-204AL (DO-41) package with two standard packing formats: 5,000 units per tape-and-reel (ordering code 1M200Z) and 3,000 units per ammo box (ordering code 1M200Z A0G). Both variants use pure tin-plated leads compliant with J-STD-002 solderability requirements and meet JESD 201 Class 2 whisker resistance. No surface-mount or alternate package variants exist for the 1M200Z.
