Product details

Overview

SMBG6.0HE3/5B from Vishay General Semiconductor is a uni-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping inductive switching transients and ESD events on power and signal lines. It features 6.0 V stand-off voltage (V_WM), 6.67–7.37 V breakdown voltage (V_BR) at 10 mA, 600 W peak pulse power (10/1000 µs), 58.3 A peak pulse current (I_PPM), and 10.3 V maximum clamping voltage (V_C) - deployed in automotive sensor protection and industrial I/O interfaces.

For engineers reviewing the SMBG6.0HE3/5B datasheet, SMBG6.0HE3/5B pinout, SMBG6.0HE3/5B application, or SMBG6.0HE3/5B equivalent, key selection criteria include AEC-Q101 qualification, 150 °C max junction temperature, RoHS-compliant matte tin plating, MSL Level 1 reflow compatibility (260 °C peak), and unidirectional polarity with cathode band marking.

Technical Context

This device operates as a voltage-clamping protector in series with sensitive downstream circuitry, conducting only when reverse voltage exceeds V_BR to divert surge energy away from ICs or MOSFETs. Its glass-passivated junction ensures stable leakage (<800 µA at V_WM) and fast response time (<1 ns), critical for protecting CAN, LIN, and sensor supply rails against ISO 7637-2 pulses.

The SMBG6.0HE3/5B is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits 20 °C/W junction-to-lead thermal resistance, enabling reliable operation under repeated transient stress when mounted on 5.0 mm × 5.0 mm copper pads per terminal. Its DO-215AA footprint supports automated placement and meets UL 94 V-0 flammability requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system supply margin for 5 V rail protection.
V_BR @ I_T=10 mA	6.67–7.37 V - Verified breakdown threshold defining turn-on precision; tight 10% tolerance enables predictable overvoltage trip point.
V_C @ I_PPM	10.3 V - Clamped voltage during 58.3 A surge; ensures protected ICs remain below absolute maximum ratings (e.g., 12 V tolerant inputs).
P_PPM	600 W - Peak pulse power handling (10/1000 µs waveform); sufficient for automotive load-dump and inductive kick suppression.
I_PPM	58.3 A - Maximum surge current it can safely shunt without degradation; validated per Fig. 1 derating curves up to T_A = 125 °C.
T_J max	150 °C - Maximum junction temperature; supports under-hood automotive environments and high-ambient industrial control cabinets.
MSL Level	Level 1 (J-STD-020) - No floor life limitation; compatible with standard SMT reflow profiles up to 260 °C peak.

Pinout & Package

DO-215AA (SMBG) surface-mount package: low-profile, gull-wing leads, 0.235–0.255 inch (5.97–6.48 mm) body length, 0.130–0.155 inch (3.30–3.94 mm) body width, cathode band marked on one end.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward conduction path (for uni-directional operation)	Connected to ground or low-side return; completes surge current path during reverse-biased clamping event.
Cathode (banded end)	Reverse-biased clamping node	Connected to protected line (e.g., 5 V supply or CAN_H); conducts when line voltage exceeds V_BR relative to anode.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control, ADAS, and body electronics.
Glass passivated junction	Stable V_BR tolerance and low leakage (<800 µA) across -55 °C to +150 °C; eliminates parameter drift in harsh environments.
600 W peak pulse power (10/1000 µs)	Handles ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump) without failure - no external heat sinking needed.
Matte tin plated leads	Complies with J-STD-002 and JESD 22-B102 solderability standards; HE3 suffix meets JESD 201 Class 2 whisker resistance for long-term reliability.
UL 94 V-0 molding compound	Self-extinguishing encapsulation prevents flame propagation in enclosed enclosures - mandated for industrial safety certifications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ6.0A-E3/5B	Same DO-215AB (SMB) package but lower 600 W rating; identical V_WM/V_BR/V_C, but not AEC-Q101 qualified.	Commercial-grade only; unsuitable for automotive OEM designs requiring qualification evidence.	Select SMBJ6.0A-E3/5B only for cost-sensitive consumer or industrial applications where AEC-Q101 is not mandated.
1.5SMC6.0A	DO-214AB (SMC) package - larger footprint (7.11 × 6.22 mm), higher 1500 W P_PPM, same electrical specs but different thermal profile.	Used where board space allows larger package and higher surge margin is needed (e.g., AC input stages).	Choose 1.5SMC6.0A when PCB layout permits larger pad area and system-level surge testing requires >600 W headroom.

Compared with SMBJ6.0A-E3/5B and 1.5SMC6.0A, SMBG6.0HE3/5B uniquely combines AEC-Q101 qualification, DO-215AA compactness (vs. SMC), and automotive-grade whisker resistance - making it the only option meeting Tier-1 automotive gate requirements without footprint or qualification compromise.

FAQ

What is the polarity configuration of SMBG6.0HE3/5B?

SMBG6.0HE3/5B is a uni-directional transient voltage suppressor diode. Its cathode is marked with a band on the package body, and it conducts only when the cathode is biased positively relative to the anode - making it suitable for protecting positive supply rails or signal lines referenced to ground. This polarity differs from bi-directional variants (e.g., SMBG6.0CA) that suppress surges in both directions without polarity sensitivity.

Does SMBG6.0HE3/5B meet automotive qualification standards?

Yes, SMBG6.0HE3/5B is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88456, Revision 12-Nov-12). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD - validating its suitability for under-hood and chassis-mounted automotive electronics such as engine control units and ADAS sensor modules.

What is the maximum clamping voltage of SMBG6.0HE3/5B at rated surge current?

The maximum clamping voltage (V_C) of SMBG6.0HE3/5B is 10.3 V at its rated peak pulse current (I_PPM) of 58.3 A, measured using the standardized 10/1000 µs double-exponential waveform. This value ensures protected circuits - such as 12 V-tolerant microcontrollers or CAN transceivers - remain within safe operating limits during worst-case transient events.

How does the HE3 suffix affect the SMBG6.0HE3/5B specification?

The HE3 suffix on SMBG6.0HE3/5B indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - distinguishing it from the commercial-grade E3 variant. The HE3 version uses enhanced matte tin plating and undergoes additional automotive reliability screening, making SMBG6.0HE3/5B appropriate for mission-critical automotive applications where long-term interconnect integrity is mandatory.

Can SMBG6.0HE3/5B be used in place of SMBG6.0A-E3/5B?

No - SMBG6.0HE3/5B and SMBG6.0A-E3/5B are not interchangeable without design review. While both share identical electrical parameters and DO-215AA packaging, SMBG6.0HE3/5B is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance, whereas SMBG6.0A-E3/5B is commercial-grade only. Substituting SMBG6.0A-E3/5B in an automotive design would invalidate qualification compliance and risk field failure under extended thermal cycling.
