Product details

Overview

ST13005 from STMicroelectronics is a high-voltage fast-switching NPN power transistor in TO-220 package, rated for 700 V V_CES, 4 A continuous collector current, and 75 W total dissipation at T_c ≤ 25 °C. It features low dynamic parameter spread, cellular emitter structure, and wide RBSOA-designed for electronic ballasts and switch-mode power supplies.

For engineers reviewing the ST13005 datasheet, ST13005 pinout, ST13005 application, or ST13005 equivalent, key selection criteria include V_CEO = 400 V, t_s = 1.5 μs (resistive load), h_FE group pre-selection (A–F), and R_thj-case = 1.7 °C/W thermal resistance.

Technical Context

This device employs high-voltage multi-epitaxial planar technology with planar edge termination to achieve robust switching performance under high-voltage stress. Its cellular emitter design enhances switching speed while preserving ruggedness across the reverse-biased safe operating area (RBSOA).

It supports both resistive and inductive load switching, with documented storage time (t_s) of 1.5 μs and fall time (t_f) of 0.2 μs under specified test conditions (I_C = 2 A, V_CC = 125 V, I_B1 = –I_B2 = 0.4 A, t_p = 30 μs).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	700 V - maximum collector-emitter voltage with base open, enabling use in high-voltage flyback and resonant converters
I_C (cont.)	4 A - continuous DC collector current rating at T_c = 25 °C, defining steady-state power handling capability
P_TOT	75 W - total power dissipation limit at case temperature ≤ 25 °C, requiring heatsink sizing per R_thj-case = 1.7 °C/W
t_s / t_f	1.5 μs / 0.2 μs - measured storage and fall times on resistive load, directly impacting switching loss and frequency capability
h_FE (Group D)	21–32 - pre-selected DC current gain range at I_C = 1 A, V_CE = 5 V, reducing design margin uncertainty across production lots
V_CE(sat)	0.6 V @ I_C = 2 A, I_B = 0.5 A - low saturation voltage minimizes conduction loss in hard-switched topologies

Pinout & Package

ST13005 is housed in a TO-220 type A package with isolated mounting tab (collector-connected), standard 3-pin vertical configuration, and ECOPACK® environmental compliance.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Emitter terminal	Low-impedance current return path; connected to ground or low-side reference in common-emitter switching configurations
2 (Base)	Control input	Receives drive current to bias transistor into saturation or cutoff; requires external current-limiting resistor for reliable turn-on/turn-off
3 (Collector)	High-voltage output node	Connected to primary winding or high-side rail; electrically tied to metal tab for thermal conduction and mechanical mounting

Key Features

Feature	Design Value
Cellular emitter structure	Enables simultaneous high-speed switching and wide RBSOA by distributing current density and suppressing localized thermal runaway
Planar edge termination	Improves voltage blocking uniformity and reduces leakage at high V_CE, supporting stable operation up to 700 V
Pre-selected h_FE groups (A–F)	Minimizes lot-to-lot variation in current gain, simplifying drive circuit design and reducing need for gain compensation
R_thj-case = 1.7 °C/W	Allows efficient heat transfer to heatsink, enabling 75 W dissipation with modest thermal interface resistance and finned aluminum mounting

Applications

Electronic Ballast

SMPS Primary Switch

Use Scenario: High-frequency AC lamp ignition and regulation in fluorescent lighting systems.

IC Role / Device Role / Timing Role: NPN power switch in half-bridge or Royer oscillator topology, operating at 20–60 kHz.

Use Value: Fast t_s/t_f and wide RBSOA ensure reliable zero-voltage switching transitions and withstand lamp arc re-ignition surges.

Use Scenario: Primary-side switching element in offline flyback or forward converters delivering 20–100 W.

IC Role / Device Role / Timing Role: Hard-switched main power transistor driven by UC384x or similar controller.

Use Value: 700 V V_CES rating accommodates reflected transients and line surges without snubber overdesign.

DC-DC Converter

Inductive Load Driver

Use Scenario: Isolated DC-DC conversion in industrial control power supplies.

IC Role / Device Role / Timing Role: High-side switch in push-pull or full-bridge configuration driving transformer primary.

Use Value: Low V_CE(sat) (0.6 V) and controlled h_FE reduce conduction loss and simplify gate/base drive staging.

Use Scenario: Solenoid, relay, or motor coil driver in automation equipment.

IC Role / Device Role / Timing Role: Saturated switch controlling inductive energy release via freewheeling diode.

Use Value: Documented inductive-load t_s (Figure 9) and RBSOA support repetitive 8 A peak current pulses without secondary breakdown.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage NPN power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ST13003	V_CES = 400 V, I_C = 1.5 A, P_TOT = 25 W - lower voltage/current rating and thermal capability	Suitable only for <20 W SMPS or low-voltage ballasts; cannot replace ST13005 in 700 V designs	Select when cost sensitivity outweighs voltage headroom needs and system derating is acceptable
MJE13005	Same V_CES = 700 V, I_C = 4 A, but h_FE ungrouped (8–40), R_thj-case = 2.0 °C/W - wider gain spread and higher thermal resistance	Requires additional drive margining and larger heatsink; less consistent across production batches	Choose only if ST13005 supply is constrained and design allows for gain variability and thermal overhead

Compared with ST13003 and MJE13005, ST13005 delivers tighter h_FE control, lower thermal resistance, and guaranteed 700 V blocking-making it optimal for high-reliability, high-density fluorescent ballasts and universal-input SMPS where parameter consistency and thermal efficiency are critical.

FAQ

Is ST13005 RoHS-compliant and lead-free?

Yes, ST13005 is manufactured in ECOPACK®-compliant TO-220 packages meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The device uses lead-free terminations and halogen-free molding compounds, with full compliance documentation available through ST's quality portal.

What is the recommended base drive current for reliable saturation?

For full saturation at I_C = 4 A, ST specifies I_B = 1 A (h_FE min ≈ 4). However, typical design uses I_B = 0.5–0.8 A with Group D/F devices. A 47 Ω series resistor from a 12 V driver yields ~0.25 A base current-sufficient for I_C ≤ 2 A operation.

Can ST13005 be used in avalanche mode?

No-ST13005 is not rated or characterized for repetitive avalanche operation. Its safe operating area excludes second breakdown under unclamped inductive switching. External clamping (e.g., RCD snubber or TVS) is mandatory for inductive loads to prevent destructive failure.

How does h_FE grouping affect circuit design?

Each ST13005 unit is pre-tested and marked (A/C/D/E/F) to indicate its h_FE range at I_C = 1 A. Designers can select a group matching their drive capability: Group A (15–32) suits low-base-current drivers; Group F (31–40) enables minimal base drive but requires tighter thermal control due to higher gain-related instability risk.
