The short answer is that the ordained, elected, authoritative office of Deacon per I Timothy 3 is for men only.
Ecclesiastical authoritative office, in accordance with Scripture and the priority in Creation, is for men only. It is contrary to Scripture for women to exercise ecclesiastical authority over men or to be ordained for such authority.
It is the responsibility and authority of Deacons to oversee mercy ministry in the church in such a way as to involve women and men in mercy (diaconal) ministry. Those so involved are not ordained, elected and do not exercise authority.
In accordance with Scripture, it is necessary that women and men be involved in diaconal ministry. The office of "Deacon" is not confused with "diaconal" (mercy, servant) ministry. For example a paralegal does "legal" work but is not to be confused with an attorney. Even though the paralegal is necessary, knowledgeable, and capable she or he is not licensed, professional standards accountable, or Bar pass certified as is the attorney and is not "set apart" to "pass the bar" and practice law in court.
There is a nonauthoritative "office" of servant widow for women per I Timothy 5. It requires a widow, aged 60, a reputation for serving well, etc. This office is not ordained, or authoritative. It may, be supported (paid) by the church, and vows may be taken for it. It might be termed "deaconess" (my opinion would add if great care is taken to differentiate it from the authoritative office of Deacon.
It is not clear to me whether Scripture permits the office of "servant widow" is to be elected, I need to study that further.
