Product details
Overview
FMMT413TC from Zetex Semiconductors is an NPN silicon planar bipolar transistor engineered for controlled avalanche-mode operation, with V(BR)CES = 150 V, IUSB = 25 A (pulsed), and SOT-23 package inductance of 2.5 nH - deployed in high-speed laser diode driver circuits requiring sub-25 ns current pulses.
For engineers reviewing the FMMT413TC datasheet, FMMT413TC pinout, FMMT413TC application, or FMMT413TC equivalent, key selection criteria include avalanche energy handling (CCE = 4.7 nF, VC = 130 V), tight BVCBO tolerance (150 V min), and low-inductance SOT-23 lead geometry critical for edge fidelity in pulse generators.
Technical Context
The FMMT413TC operates in avalanche breakdown under controlled pulsed conditions, where collector-emitter voltage exceeds BVCEO (50 V) but remains below BVCES (150 V) during transient conduction. Its design relies on precise doping profiles and minimized parasitic inductance to sustain 25 A peak avalanche current without second-breakdown failure.
It delivers fast switching edges due to ultra-low LCE (2.5 nH), fT = 150 MHz, and minimal output capacitance (COBO = 2 pF at 10 V), enabling reliable operation in repetitive-pulse circuits up to 10 kHz with CCE = 4.7 nF and dI/dt > 5 mA/ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)CES | 150 V - Maximum collector-emitter sustaining voltage in avalanche mode with base open |
| IUSB | 25 A - Peak unclamped avalanche current at VC = 130 V, CCE = 4.7 nF, loop inductance ≈12 nH |
| LCE | 2.5 nH - Measured collector-emitter inductance in standard SOT-23 leads, critical for edge speed |
| fT | 150 MHz - Transition frequency at IC = 10 mA, VCE = 5 V, supports high-speed switching |
| VCE(sat) | 150 mV - Low saturation voltage at IC = 10 mA, IB = 1 mA, minimizing conduction loss |
| COBO | 2 pF - Output capacitance at VCB = 10 V, reduces Miller effect in fast-switching nodes |
Pinout & Package
SOT-23 plastic surface-mount package with gull-wing leads; standardized 3-pin outline per JEDEC TO-236AB, footprint compatible with automated placement and reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal during avalanche conduction | Low-impedance path for 25 A pulse return; connected to ground plane with minimal trace inductance |
| 2 (Base) | Control gate for avalanche initiation timing | Driven with fast-rising edge (≥5 mA/ns) to trigger reproducible breakdown onset |
| 3 (Collector) | High-voltage switched node | Connected to charged capacitor (CCE) and laser diode anode; withstands 130 V transient |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated operation | Guaranteed 25 A unclamped avalanche current with defined test circuit (CCE = 4.7 nF, VC = 130 V) |
| Ultra-low package inductance | 2.5 nH collector-emitter inductance enables <25 ns current rise time in optimized layouts |
| Tight BVCBO distribution | 150 V minimum collector-base breakdown ensures consistent avalanche triggering across production lots |
| High fT and low COBO | 150 MHz fT and 2 pF COBO support stable high-frequency bias control and minimal ringing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar avalanche-mode switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN2012Z | Higher BVCEO (60 V), lower IUSB (18 A), SOT-89 package (higher thermal mass) | Preferred for lower-repetition-rate, higher-duty-cycle avalanche use with heatsinking | Select when continuous power dissipation >150 mW is required and board space allows larger footprint |
| BC847B | No avalanche rating; max IC = 100 mA continuous; not rated for unclamped inductive or capacitive discharge | Only suitable for linear amplification or saturated switching below 50 V and 100 mA | Reject for any avalanche, pulse-generator, or laser-driver application - lacks specified IUSB and BVCBO margin |
Compared with ZXTN2012Z, FMMT413TC offers superior edge speed and pulse fidelity due to lower LCE and tighter BVCBO control, while BC847B is functionally incompatible for avalanche tasks and must be excluded from such designs.

FAQ
What is the maximum allowable avalanche energy for FMMT413TC?
The FMMT413TC does not specify a single energy rating (Joules), but its safe avalanche operation is defined by test conditions: 25 A peak current at VC = 130 V with CCE = 4.7 nF and loop inductance ≈12 nH. Energy per pulse is approximately 8.3 mJ under those conditions, and repetition rate must stay ≤10 kHz to limit junction temperature rise.
Can FMMT413TC be used in linear amplifier configurations?
No - the FMMT413TC is process-optimized and characterized exclusively for avalanche-mode switching. Its hFE (min 50) and VCE(sat) are specified only at IC = 10 mA, and it lacks linearity, gain flatness, or SOA curves needed for analog amplification. Use only in pulsed avalanche or saturated-switch applications.
Is the SOT-23 footprint of FMMT413TC compatible with JEDEC MO-215?
Yes - the FMMT413TC uses the standard SOT-23 (TO-236AB) package per JEDEC MO-215, with pin 1 (Emitter), pin 2 (Base), pin 3 (Collector) in top-view orientation. Dimensions match: length 2.67–3.05 mm, width 1.20–1.40 mm, height ≤1.10 mm, and 0.95 mm lead pitch.
Does FMMT413TC require external snubbing or clamping components?
No external clamping is required when operated within its defined avalanche test circuit (CCE, loop inductance, VC). However, a series base resistor (typically 10–47 Ω) is mandatory to limit dI/dt into the base and ensure controlled avalanche initiation; omitting it risks erratic triggering or device failure.
